Method Summary

Formula	formula()
Histogram	getHistogram()
void	logResults(int numSamples) If a log file has been specified, prints the results so far to that file.
void	printResults(java.io.PrintStream s) Prints the results of this query to the given stream.
void	printVarianceResults(java.io.PrintStream s) Prints across-run statistics.
void	setPosterior(ve.Factor posterior) Throws an UnsupportedOperationException.
void	updateStats(PartialWorld world, double weight) Updates the within-run statistics for this query to reflect the given world sampled with the given weight.

FormulaQuery

public FormulaQuery(Formula formula)

Method Detail

formula

public Formula formula()

printResults

public void printResults(java.io.PrintStream s)

Description copied from interface: Query

Prints the results of this query to the given stream.

Specified by:

printResults in interface Query

Overrides:

printResults in class ArgSpecQuery

logResults

public void logResults(int numSamples)

Description copied from class: AbstractQuery

If a log file has been specified, prints the results so far to that file.

This default implementation does nothing.

Specified by:

logResults in interface Query

Overrides:

logResults in class ArgSpecQuery

Parameters:

numSamples - the number of samples taken by the inference engine so far (can be set to zero for non-sampling inference engines)

updateStats

public void updateStats(PartialWorld world,
                        double weight)

Description copied from interface: Query

Updates the within-run statistics for this query to reflect the given world sampled with the given weight. The world must be complete enough to define values for all the variables returned by getVariables.

The effects of calling both updateStats and setPosterior in the same run are not defined.

Specified by:

updateStats in interface Query

Overrides:

updateStats in class ArgSpecQuery

setPosterior

public void setPosterior(ve.Factor posterior)

Description copied from class: AbstractQuery

Throws an UnsupportedOperationException.

Specified by:

setPosterior in interface Query

Overrides:

setPosterior in class ArgSpecQuery

Parameters:

posterior - factor whose set of variables is the same as the collection returned by getVariables, and whose entries sum to 1

zeroOut

public void zeroOut()

Description copied from interface: Query

Ends the current run, records across-run statistics for it, and clears the within-run statistics.

Specified by:

zeroOut in interface Query

Overrides:

zeroOut in class ArgSpecQuery

printVarianceResults

public void printVarianceResults(java.io.PrintStream s)

Description copied from interface: Query

Prints across-run statistics.

Specified by:

printVarianceResults in interface Query

Overrides:

printVarianceResults in class ArgSpecQuery

getHistogram

public Histogram getHistogram()

Overrides:

getHistogram in class ArgSpecQuery
