C++ (Cpp) retrieveExpressionInfo示例

示例#1

文件： StackVisitor.cpp 项目： houzhenggang/webkit

void StackVisitor::Frame::computeLineAndColumn(unsigned& line, unsigned& column)
{
    CodeBlock* codeBlock = this->codeBlock();
    if (!codeBlock) {
        line = 0;
        column = 0;
        return;
    }

    int divot = 0;
    int unusedStartOffset = 0;
    int unusedEndOffset = 0;
    unsigned divotLine = 0;
    unsigned divotColumn = 0;
    retrieveExpressionInfo(divot, unusedStartOffset, unusedEndOffset, divotLine, divotColumn);

    line = divotLine + codeBlock->ownerExecutable()->lineNo();
    column = divotColumn + (divotLine ? 1 : codeBlock->firstLineColumnOffset());
}
