Method Detail

getLookupAlgorithm

public LookupAlgorithm getLookupAlgorithm(DictionaryEngine dictEngine)
                                   throws org.apache.uima.analysis_engine.annotator.AnnotatorInitializationException

Description copied from interface: LookupInitializer

Gets the LookupAlgorithm to be used to perform the lookup operations. Properties specified from the descriptor will be passed in to customize the behavior of the algorithm.

Specified by:

getLookupAlgorithm in interface LookupInitializer

Parameters:

dictEngine - DictionaryEngine that will execute lookup operations.

Returns:

LookupAlgorithm that will be used for lookup operations.

Throws:

org.apache.uima.analysis_engine.annotator.AnnotatorInitializationException

getLookupTokenIterator

public java.util.Iterator getLookupTokenIterator(org.apache.uima.jcas.JCas jcas)
                                          throws org.apache.uima.analysis_engine.annotator.AnnotatorInitializationException

Description copied from interface: LookupInitializer

Gets an iteration of tokens that represent the finest grain used for a lookup operation. These tokens may be as simple as a single word or perhaps an entire phrase.

Specified by:

getLookupTokenIterator in interface LookupInitializer

Parameters:

jcas - Use the JCas to pull out pre-existing feature structures to build the LookupToken objects. Add attributes to the LookupToken objects as you see fit.

Returns:

Iterator over LookupToken objects.

Throws:

org.apache.uima.analysis_engine.annotator.AnnotatorInitializationException

getLookupWindowIterator

public java.util.Iterator getLookupWindowIterator(org.apache.uima.jcas.JCas jcas)
                                           throws org.apache.uima.analysis_engine.annotator.AnnotatorInitializationException

Description copied from interface: LookupInitializer

Gets an iteration of windows. A window is used to scope which LookupToken objects are passed to the LookupAlgorithm.

Specified by:

getLookupWindowIterator in interface LookupInitializer

Parameters:

jcas - Use the JCas to pull out pre-existing feature structures to build LookupAnnotation objects.

Returns:

Iterator over org.apache.uima.jcas.tcas.Annotation objects, each representing a window.

Throws:

org.apache.uima.analysis_engine.annotator.AnnotatorInitializationException

getContextMap

public java.util.Map getContextMap(org.apache.uima.jcas.JCas jcas,
                                   int windowBegin,
                                   int windowEnd)

Description copied from interface: LookupInitializer

Gets context for the specified window.

Specified by:

getContextMap in interface LookupInitializer

Returns:
