Class NoCachingCacheProcessor

java.lang.Object
  calhoun.analysis.crf.solver.CacheProcessorBasic
      calhoun.analysis.crf.solver.NoCachingCacheProcessor

All Implemented Interfaces:

CacheProcessor

public class NoCachingCacheProcessor
extends CacheProcessorBasic

a dummy cache processor that fulfills the interface but doesn't cache. It always retrieves values by calling the FeatureManager evlaute functions. Does not work with NodeBoundary features.

Method Detail

isAllPaths

public boolean isAllPaths()

true if all paths (valid and invalid) are to be evaluated during the viterbi search. Defaults to false.

Returns:

true if all paths are to be examined

setAllPaths

public void setAllPaths(boolean allPaths)

sets whether all paths (valid and invalid) are to be evaluated during the viterbi search. Defaults to false.

Parameters:

allPaths - allPath true if all paths are to be examined

setTrainingData

public void setTrainingData(ModelManager fm,
                            java.util.List<? extends TrainingSequence<?>> data)

Specified by:

setTrainingData in interface CacheProcessor

Overrides:

setTrainingData in class CacheProcessorBasic

getInvalidTransitions

public boolean[] getInvalidTransitions()

getFeatureSums

public double[] getFeatureSums()

Specified by:

getFeatureSums in interface CacheProcessor

Overrides:
