Constructor Detail

WordTokenizer

public WordTokenizer(Reader input,
             String[] separatorTokens,
             boolean returnSeparators,
             boolean aCaseSensitive)

full constructor.

Parameters:

input - - a reader that reads the string to be parsed

separatorTokens - - array of separator strings

returnSeparators - - true when nextToken() should return separators, false otherwise

aCaseSensitive - - true when separators are caseSensitive (faster), false otherwise (slower)
