The QScriptString class acts as a handle to "interned" strings 在 QScriptEngine .
QScriptString can be used to achieve faster (repeated) property getting/setting, and comparison of property names, of script 对象。
To get a QScriptString representation of a string, pass the string to QScriptEngine.toStringHandle (). The typical usage pattern is to register one or more pre-defined strings when setting up your script environment, then subsequently use the relevant QScriptString as argument to e.g. QScriptValue.property ().
Call the toString () function to obtain the string that a QScriptString represents.
Call the toArrayIndex () function to convert a QScriptString to an array index. This is useful when 使用 QScriptClass to implement array-like objects.
Constructs an invalid QScriptString .
构造新 QScriptString that is a copy of other .

Attempts to convert this QScriptString 到 QtScript array index, and returns the 结果。
