DefaultSymbolFactory

public DefaultSymbolFactory()

Deprecated. as of CUP v11a replaced by the new java_cup.runtime.ComplexSymbolFactory

DefaultSymbolFactory for CUP. Users are strongly encoraged to use ComplexSymbolFactory instead, since it offers more detailed information about Symbols in source code. Yet since migrating has always been a critical process, You have the chance of still using the oldstyle Symbols.
