Operand * SymbolTable::getLocalSymbol ( T_STRING &  key) const

It is like "getSymbol()" but lookup is made **only** on local scope.

Here is the caller graph for this function:

Operand * SymbolTable::getSymbol ( T_STRING &  key) const

Return the symbol asosiated to the key. Key should be the Operand Name. Generaly, Operands are Constans, Variables, Functions ... The search is made in local scope first, then on the parent (global) scope and so on. For local lookup only see "getLocalSymbol()" If the symbol is not founded, return NULL

bool SymbolTable::populateSymbol ( Operand *  o)

Make this symbol to 'upgrade' it's scope to the next (parent) Table. It method is used to "export" a step's variable.
