示例1: getOwnPropertySlot
bool GlobalObject::getOwnPropertySlot(JSC::ExecState* exec,
const JSC::Identifier& propertyName,
JSC::PropertySlot& slot)
{
QScriptEnginePrivate *engine = scriptEngineFromExec(exec);
if (propertyName == exec->propertyNames().arguments && engine->currentFrame->argumentCount() > 0) {
JSC::JSValue args = engine->scriptValueToJSCValue(engine->contextForFrame(engine->currentFrame)->argumentsObject());
slot.setValue(args);
return true;
}
if (customGlobalObject)
return customGlobalObject->getOwnPropertySlot(exec, propertyName, slot);
return JSC::JSGlobalObject::getOwnPropertySlot(exec, propertyName, slot);
}示例2: pushContext
/*!
Enters a new execution context and returns the associated
QScriptContext object.
Once you are done with the context, you should call popContext() to
restore the old context.
By default, the `this' object of the new context is the Global Object.
The context's \l{QScriptContext::callee()}{callee}() will be invalid.
Unlike pushContext(), the default scope chain is reset to include
only the global object and the QScriptContext's activation object.
\sa QScriptEngine::popContext()
