public java.lang.String addSymbol(char[] buffer,
                                  int offset,
                                  int length)

offset - The offset into the buffer of the new symbol.
length - The length of the new symbol in the buffer.

containsSymbol

public boolean containsSymbol(java.lang.String symbol)
Returns true if the symbol table already contains the specified symbol.

Overrides:
containsSymbol in class SymbolTable
Parameters:
symbol - The symbol to look for.

containsSymbol

public boolean containsSymbol(char[] buffer,
