Method Detail

setIgnoreStopWords

public void setIgnoreStopWords(boolean ignoreStopWords)

If set to TRUE, stopwords like 'of, on' are ignored during creation and retrieval operations.

Parameters:

ignoreStopWords - the ignoreStopWords to set

add

public void add(List<Token> tokens,
                Set<org.semanticweb.owlapi.model.OWLEntity> entities,
                List<Token> originalTokens)

Adds all given entities to the end of the path resulting from the given tokens.

Parameters:

tokens - tokens to locate insertion point for entities

entities - entities to add

add

public void add(List<Token> tokens,
                Set<org.semanticweb.owlapi.model.OWLEntity> entities)

add

public void add(List<Token> tokens,
                org.semanticweb.owlapi.model.OWLEntity entity)
