Method Detail

initialize

public static void initialize(PropertiesMap propertiesMap)
                       throws ClassNotFoundException

Initializes the DataFactory with the given PropertiesMap. The classes that will be used within ABL4J (implementations of IConstituent, ISentence, IWord, ITree and ITreeBank) are loaded here. These classes can be set by modifying the Properties AblProperties.CONSTITUENT_CLASS, AblProperties.SENTENCE_CLASS, AblProperties.WORD_CLASS, AblProperties.TREE_CLASS and AblProperties.TREEBANK_CLASS . The ABL4J-Implementation (found in org.schwiebert.abl4j.data) will be used by default.

Parameters:

propertiesMap - the properties map

Throws:

ClassNotFoundException - if one of the data classes cannot be loaded

getMapping

public static IWordMapping getMapping()

getWord

public static IWord getWord(Object data)

This procedure associates to each unique space and newline delimited input string, a word, a unique number for internal representation and stores this in the Word class.

newConstituent

public static IConstituent newConstituent()

newConstituent

public static IConstituent newConstituent(ISentence sentence,
                                          int begin,
                                          int end)

newTree

public static ITree newTree()

newSentence

public static ISentence newSentence()

newWord

public static IWord newWord(int index)

Creates a new word which will be registered within a WordMapping.

Parameters:

index -

Returns:

newTreeBank

public static ITreeBank newTreeBank()

setMapping
