Method Detail

parse

public static java.lang.String parse(java.lang.String str,
                                     java.util.Map syms,
                                     boolean partialOk)
                              throws ParseException

Returns:

a String with the variables replaced by their values.

Throws:

ParseException - if there was a problem parsing the String, or if a variable could not be found in the SymbolTable.
