C++ (Cpp) TSymbol::getAsVariable示例

示例#1

文件： ParseContextBase.cpp 项目： dumganhar/bgfx

// Return a writable version of the variable 'name'.
//
// Return nullptr if 'name' is not found.  This should mean
// something is seriously wrong (e.g., compiler asking self for
// built-in that doesn't exist).
TVariable* TParseContextBase::getEditableVariable(const char* name)
{
    bool builtIn;
    TSymbol* symbol = symbolTable.find(name, &builtIn);

    assert(symbol != nullptr);
    if (symbol == nullptr)
        return nullptr;

    if (builtIn)
        makeEditable(symbol);

    return symbol->getAsVariable();
