This class represents pixel data packed such that the N samples which make up a single pixel are stored in a single data array element, and each data data array element holds samples for only one pixel. This class supports TYPE_BYTE , TYPE_USHORT , TYPE_INT data types. All data array elements reside in the first bank of a DataBuffer. Accessor methods are provided so that the image data can be manipulated directly. Scanline stride is the number of data array elements between a given sample and the corresponding sample in the same column of the next scanline. Bit masks are the masks required to extract the samples representing the bands of the pixel. Bit offsets are the offsets in bits into the data array element of the samples representing the bands of the pixel.

The following code illustrates extracting the bits of the sample representing band b for pixel x,y from DataBuffer data:

      int sample = data.getElem(y * scanlineStride + x);
      sample = (sample & bitMasks[b]) >>> bitOffsets[b];
 
Constructs a SinglePixelPackedSampleModel with bitMasks.length bands. Each sample is stored in a data array element in the position of its corresponding bit mask. Each bit mask must be contiguous and masks must not overlap.
Parameters
dataTypeThe data type for storing samples.

hThe height (in pixels) of the region of the image data described.
bitMasksThe bit masks for all bands.
Throws
IllegalArgumentExceptionif dataType is not either DataBuffer.TYPE_BYTE, DataBuffer.TYPE_USHORT, or DataBuffer.TYPE_INT
Constructs a SinglePixelPackedSampleModel with bitMasks.length bands and a scanline stride equal to scanlineStride data array elements. Each sample is stored in a data array element in the position of its corresponding bit mask. Each bit mask must be contiguous and masks must not overlap.

Return
a SinglePixelPackedSampleModel with the specified width and height.
Throws
IllegalArgumentExceptionif w or h is not greater than 0
Creates a DataBuffer that corresponds to this SinglePixelPackedSampleModel. The DataBuffer's data type and size will be consistent with this SinglePixelPackedSampleModel. The DataBuffer will have a single bank.
This creates a new SinglePixelPackedSampleModel with a subset of the bands of this SinglePixelPackedSampleModel. The new SinglePixelPackedSampleModel can be used with any DataBuffer that the existing SinglePixelPackedSampleModel can be used with. The new SinglePixelPackedSampleModel/DataBuffer combination will represent an image with a subset of the bands of the original SinglePixelPackedSampleModel/DataBuffer combination.
Throws
RasterFormatExceptionif the length of the bands argument is greater than the number of bands in the sample model.
Returns the bit masks for all bands.
Return
the bit masks for all bands.
Returns the bit offsets into the data array element representing a pixel for all bands.

Returns the runtime class of an object. That Class object is the object that is locked by static synchronized methods of the represented class.
Return
The java.lang.Class object that represents the runtime class of the object. The result is of type {@code Class} where X is the erasure of the static type of the expression on which getClass is called.
Returns the pixel data for the specified rectangle of pixels in a primitive array of type TransferType. For image data supported by the Java 2D API, this will be one of DataBuffer.TYPE_BYTE, DataBuffer.TYPE_USHORT, DataBuffer.TYPE_INT, DataBuffer.TYPE_SHORT, DataBuffer.TYPE_FLOAT, or DataBuffer.TYPE_DOUBLE. Data may be returned in a packed format, thus increasing efficiency for data transfers. Generally, obj should be passed in as null, so that the Object will be created automatically and will be of the right primitive data type.

The following code illustrates transferring data for a rectangular region of pixels from DataBuffer db1, whose storage layout is described by SampleModel sm1, to DataBuffer db2, whose storage layout is described by SampleModel sm2. The transfer will generally be more efficient than using getPixels/setPixels.

 	     SampleModel sm1, sm2;
	     DataBuffer db1, db2;
 	     sm2.setDataElements(x, y, w, h, sm1.getDataElements(x, y, w,
                           h, null, db1), db2);
 
Using getDataElements/setDataElements to transfer between two DataBuffer/SampleModel pairs is legitimate if the SampleModels have the same number of bands, corresponding bands have the same number of bits per sample, and the TransferTypes are the same.

If obj is non-null, it should be a primitive array of type TransferType. Otherwise, a ClassCastException is thrown. An ArrayIndexOutOfBoundsException may be thrown if the coordinates are not in bounds, or if obj is non-null and is not large enough to hold the pixel data.

Parameters
xThe minimum X coordinate of the pixel rectangle.
yThe minimum Y coordinate of the pixel rectangle.
wThe width of the pixel rectangle.
hThe height of the pixel rectangle.
objIf non-null, a primitive array in which to return the pixel data.
dataThe DataBuffer containing the image data.
Return
the data elements for the specified region of pixels.
Throws
NullPointerExceptionif data is null.
ArrayIndexOutOfBoundsExceptionif the coordinates are not in bounds, or if obj is too small to hold the output.
Returns data for a single pixel in a primitive array of type TransferType. For a SinglePixelPackedSampleModel, the array will have one element, and the type will be the same as the storage data type. Generally, obj should be passed in as null, so that the Object will be created automatically and will be of the right primitive data type.

The following code illustrates transferring data for one pixel from DataBuffer db1, whose storage layout is described by SinglePixelPackedSampleModel sppsm1, to DataBuffer db2, whose storage layout is described by SinglePixelPackedSampleModel sppsm2. The transfer will generally be more efficient than using getPixel/setPixel.

 	     SinglePixelPackedSampleModel sppsm1, sppsm2;
	     DataBufferInt db1, db2;
 	     sppsm2.setDataElements(x, y, sppsm1.getDataElements(x, y, null,
                              db1), db2);
 
Using getDataElements/setDataElements to transfer between two DataBuffer/SampleModel pairs is legitimate if the SampleModels have the same number of bands, corresponding bands have the same number of bits per sample, and the TransferTypes are the same.

Wakes up a single thread that is waiting on this object's monitor. If any threads are waiting on this object, one of them is chosen to be awakened. The choice is arbitrary and occurs at the discretion of the implementation. A thread waits on an object's monitor by calling one of the wait methods.

The awakened thread will not be able to proceed until the current thread relinquishes the lock on this object. The awakened thread will compete in the usual manner with any other threads that might be actively competing to synchronize on this object; for example, the awakened thread enjoys no reliable privilege or disadvantage in being the next thread to lock this object.

This method should only be called by a thread that is the owner of this object's monitor. A thread becomes the owner of the object's monitor in one of three ways:

  • By executing a synchronized instance method of that object.
  • By executing the body of a synchronized statement that synchronizes on the object.
  • For objects of type Class, by executing a synchronized static method of that class.

Only one thread at a time can own an object's monitor.

Throws
IllegalMonitorStateExceptionif the current thread is not the owner of this object's monitor.
Wakes up all threads that are waiting on this object's monitor. A thread waits on an object's monitor by calling one of the wait methods.

The awakened threads will not be able to proceed until the current thread relinquishes the lock on this object. The awakened threads will compete in the usual manner with any other threads that might be actively competing to synchronize on this object; for example, the awakened threads enjoy no reliable privilege or disadvantage in being the next thread to lock this object.

This method should only be called by a thread that is the owner of this object's monitor. See the notify method for a description of the ways in which a thread can become the owner of a monitor.

Throws
IllegalMonitorStateExceptionif the current thread is not the owner of this object's monitor.
Sets the data for a rectangle of pixels in the specified DataBuffer from a primitive array of type TransferType. For image data supported by the Java 2D API, this will be one of DataBuffer.TYPE_BYTE, DataBuffer.TYPE_USHORT, DataBuffer.TYPE_INT, DataBuffer.TYPE_SHORT, DataBuffer.TYPE_FLOAT, or DataBuffer.TYPE_DOUBLE. Data in the array may be in a packed format, thus increasing efficiency for data transfers.

The following code illustrates transferring data for a rectangular region of pixels from DataBuffer db1, whose storage layout is described by SampleModel sm1, to DataBuffer db2, whose storage layout is described by SampleModel sm2. The transfer will generally be more efficient than using getPixels/setPixels.

 	     SampleModel sm1, sm2;
	     DataBuffer db1, db2;
 	     sm2.setDataElements(x, y, w, h, sm1.getDataElements(x, y, w, h,
                           null, db1), db2);
 
Using getDataElements/setDataElements to transfer between two DataBuffer/SampleModel pairs is legitimate if the SampleModels have the same number of bands, corresponding bands have the same number of bits per sample, and the TransferTypes are the same.

obj must be a primitive array of type TransferType. Otherwise, a ClassCastException is thrown. An ArrayIndexOutOfBoundsException may be thrown if the coordinates are not in bounds, or if obj is not large enough to hold the pixel data.

Parameters
xThe minimum X coordinate of the pixel rectangle.
yThe minimum Y coordinate of the pixel rectangle.
wThe width of the pixel rectangle.
hThe height of the pixel rectangle.
objA primitive array containing pixel data.
dataThe DataBuffer containing the image data.
Throws
NullPointerExceptionif data is null.
ArrayIndexOutOfBoundsExceptionif the coordinates are not in bounds, or if obj is too small to hold the input.
Sets the data for a single pixel in the specified DataBuffer from a primitive array of type TransferType. For a SinglePixelPackedSampleModel, only the first element of the array will hold valid data, and the type of the array must be the same as the storage data type of the SinglePixelPackedSampleModel.

The following code illustrates transferring data for one pixel from DataBuffer db1, whose storage layout is described by SinglePixelPackedSampleModel sppsm1, to DataBuffer db2, whose storage layout is described by SinglePixelPackedSampleModel sppsm2. The transfer will generally be more efficient than using getPixel/setPixel.

 	     SinglePixelPackedSampleModel sppsm1, sppsm2;
	     DataBufferInt db1, db2;
 	     sppsm2.setDataElements(x, y, sppsm1.getDataElements(x, y, null,
                              db1), db2);
 
Using getDataElements/setDataElements to transfer between two DataBuffer/SampleModel pairs is legitimate if the SampleModels have the same number of bands, corresponding bands have the same number of bits per sample, and the TransferTypes are the same.

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 
Return
a string representation of the object.
Causes current thread to wait until another thread invokes the method or the method for this object. In other words, this method behaves exactly as if it simply performs the call wait(0).

The current thread must own this object's monitor. The thread releases ownership of this monitor and waits until another thread notifies threads waiting on this object's monitor to wake up either through a call to the notify method or the notifyAll method. The thread then waits until it can re-obtain ownership of the monitor and resumes execution.

As in the one argument version, interrupts and spurious wakeups are possible, and this method should always be used in a loop:

     synchronized (obj) {
         while (<condition does not hold>)
             obj.wait();
         ... // Perform action appropriate to condition
     }
 
This method should only be called by a thread that is the owner of this object's monitor. See the notify method for a description of the ways in which a thread can become the owner of a monitor.
Throws
IllegalMonitorStateExceptionif the current thread is not the owner of the object's monitor.
InterruptedExceptionif another thread interrupted the current thread before or while the current thread was waiting for a notification. The interrupted status of the current thread is cleared when this exception is thrown.
Causes current thread to wait until either another thread invokes the method or the method for this object, or a specified amount of time has elapsed.

The current thread must own this object's monitor.

This method causes the current thread (call it T) to place itself in the wait set for this object and then to relinquish any and all synchronization claims on this object. Thread T becomes disabled for thread scheduling purposes and lies dormant until one of four things happens:

  • Some other thread invokes the notify method for this object and thread T happens to be arbitrarily chosen as the thread to be awakened.
  • Some other thread invokes the notifyAll method for this object.
  • Some other thread interrupts thread T.
  • The specified amount of real time has elapsed, more or less. If timeout is zero, however, then real time is not taken into consideration and the thread simply waits until notified.
The thread T is then removed from the wait set for this object and re-enabled for thread scheduling. It then competes in the usual manner with other threads for the right to synchronize on the object; once it has gained control of the object, all its synchronization claims on the object are restored to the status quo ante - that is, to the situation as of the time that the wait method was invoked. Thread T then returns from the invocation of the wait method. Thus, on return from the wait method, the synchronization state of the object and of thread T is exactly as it was when the wait method was invoked.

A thread can also wake up without being notified, interrupted, or timing out, a so-called spurious wakeup. While this will rarely occur in practice, applications must guard against it by testing for the condition that should have caused the thread to be awakened, and continuing to wait if the condition is not satisfied. In other words, waits should always occur in loops, like this one:

     synchronized (obj) {
         while (<condition does not hold>)
             obj.wait(timeout);
         ... // Perform action appropriate to condition
     }
 
(For more information on this topic, see Section 3.2.3 in Doug Lea's "Concurrent Programming in Java (Second Edition)" (Addison-Wesley, 2000), or Item 50 in Joshua Bloch's "Effective Java Programming Language Guide" (Addison-Wesley, 2001).

If the current thread is interrupted by another thread while it is waiting, then an InterruptedException is thrown. This exception is not thrown until the lock status of this object has been restored as described above.

Note that the wait method, as it places the current thread into the wait set for this object, unlocks only this object; any other objects on which the current thread may be synchronized remain locked while the thread waits.

This method should only be called by a thread that is the owner of this object's monitor. See the notify method for a description of the ways in which a thread can become the owner of a monitor.

Parameters
timeoutthe maximum time to wait in milliseconds.
Throws
IllegalArgumentExceptionif the value of timeout is negative.
IllegalMonitorStateExceptionif the current thread is not the owner of the object's monitor.
InterruptedExceptionif another thread interrupted the current thread before or while the current thread was waiting for a notification. The interrupted status of the current thread is cleared when this exception is thrown.
Causes current thread to wait until another thread invokes the method or the method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.

This method is similar to the wait method of one argument, but it allows finer control over the amount of time to wait for a notification before giving up. The amount of real time, measured in nanoseconds, is given by:

 1000000*timeout+nanos

In all other respects, this method does the same thing as the method of one argument. In particular, wait(0, 0) means the same thing as wait(0).

The current thread must own this object's monitor. The thread releases ownership of this monitor and waits until either of the following two conditions has occurred:

  • Another thread notifies threads waiting on this object's monitor to wake up either through a call to the notify method or the notifyAll method.
  • The timeout period, specified by timeout milliseconds plus nanos nanoseconds arguments, has elapsed.

The thread then waits until it can re-obtain ownership of the monitor and resumes execution.

As in the one argument version, interrupts and spurious wakeups are possible, and this method should always be used in a loop:

     synchronized (obj) {
         while (<condition does not hold>)
             obj.wait(timeout, nanos);
         ... // Perform action appropriate to condition
     }
 
This method should only be called by a thread that is the owner of this object's monitor. See the notify method for a description of the ways in which a thread can become the owner of a monitor.
Parameters
timeoutthe maximum time to wait in milliseconds.
nanosadditional time, in nanoseconds range 0-999999.
Throws
IllegalArgumentExceptionif the value of timeout is negative or the value of nanos is not in the range 0-999999.
IllegalMonitorStateExceptionif the current thread is not the owner of this object's monitor.
InterruptedExceptionif another thread interrupted the current thread before or while the current thread was waiting for a notification. The interrupted status of the current thread is cleared when this exception is thrown.
