static int	UNKNOWN

Constructor Summary

Primitive(int type, String name)
Constructs the primitive of the type and name

Method Summary

static Primitive	convertFrom(GeometricObject o, int index) Constructs a primitive from a give object with index in the name.
boolean	equals(Object p) The two primitives are the same if their name and type are the same.
int	hashCode() The hashcode of a primitive is a hash code of it's name.
String	name() Name of the primitive (like "l2" in "line l2")
void	print() Print the description of the primitive (like "line l2") on a separate line
String	toString() String description of the primitive (like "line l2") - includes both type and name

Primitive

public Primitive(int type,
                 String name)

Constructs the primitive of the type and name

Method Detail

convertFrom

public static Primitive convertFrom(GeometricObject o,
                                    int index)

Constructs a primitive from a give object with index in the name. Example: if index is 4 and the object is a line the primitive will be "line l4".

toString

public String toString()

String description of the primitive (like "line l2") - includes both type and name

Overrides:

toString in class Object

print

public void print()

Print the description of the primitive (like "line l2") on a separate line

equals

public boolean equals(Object p)

The two primitives are the same if their name and type are the same. For use in hashtable representing the constraint graph

Overrides:

equals in class Object

hashCode

public int hashCode()

The hashcode of a primitive is a hash code of it's name. For use in hashtable representing the constraint graph

Overrides:

hashCode in class Object

name

public String name()

Name of the primitive (like "l2" in "line l2")

type

public int type()

Type of the primitive (like "line" in "line l2")
