de.susebox.jtopas.spi .StandardKeywordHandler

StandardKeywordHandler

public class StandardKeywordHandler implements KeywordHandler(Code)

Simple implementation of the KeywordHandler interface. This class works only with the de.susebox.jtopas.TokenizerProperties interface methods and is aware of changes in these properties. It does not cache any information and is therefore a more or less slow way to handle keywords.

This class is a bridge between arbitrary de.susebox.jtopas.Tokenizer implementations using the SPI interface KeywordHandler and any de.susebox.jtopas.TokenizerProperties implementation that does not implement the KeywordHandler interface itself.

Constructor Summary
public	StandardKeywordHandler(TokenizerProperties props) The constructor takes the de.susebox.jtopas.TokenizerProperties that provide the keywords.

Method Summary
public boolean	hasKeywords() This method can be used by a de.susebox.jtopas.Tokenizer implementation for a fast detection if keyword matching must be performed at all.
public TokenizerProperty	isKeyword(DataProvider dataProvider) This method checks if the character range given through the DataProvider comprises a keyword.

Constructor Detail

StandardKeywordHandler
public StandardKeywordHandler(TokenizerProperties props)(Code)
	The constructor takes the de.susebox.jtopas.TokenizerProperties that provide the keywords. Parameters: props - the de.susebox.jtopas.TokenizerProperties to take the keywords from

Method Detail

hasKeywords
public boolean hasKeywords()(Code)
	This method can be used by a de.susebox.jtopas.Tokenizer implementation for a fast detection if keyword matching must be performed at all. If the method returns `false` time-consuming preparations can be skipped. `true` if there actually are pattern that can be testedfor a match, `false` otherwise.

isKeyword
public TokenizerProperty isKeyword(DataProvider dataProvider) throws NullPointerException(Code)
	This method checks if the character range given through the DataProvider comprises a keyword. Parameters: dataProvider - the source to get the data from, that are checked a de.susebox.jtopas.TokenizerProperty if a keyword could be found, `null` otherwise throws: TokenizerException - failure while reading more data throws: NullPointerException - if no DataProvider is given
