PGtokenizer	back to summary
public PGtokenizer(String string, char delim) Create a tokeniser. We could have used StringTokenizer to do this, however, we needed to handle nesting of '(' ')' '[' ']' '<' and '>' as these are used by the geometric data types. Parameters string:String containing tokens delim:char single character to split the tokens Annotations @SuppressWarnings:method.invocation
