The QScriptString class acts as a handle to "interned" strings in a QScriptEngine.
QScriptString can be used to achieve faster (repeated) property getting/setting, and comparison of property names, of script objects.
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 using QScriptClass to implement array-like objects.
Constructs an invalid QScriptString.
Constructs a new QScriptString that is a copy of other.
Destroys this QScriptString.
Returns true if this QScriptString is valid; otherwise returns false.
Attempts to convert this QScriptString to a Qt Script array index, and returns the result.
If a conversion error occurs, *ok is set to false; otherwise *ok is set to true.
This function was introduced in Qt 4.6.
Returns the string that this QScriptString represents, or a null string if this QScriptString is not valid.
See also isValid().
Returns the string that this QScriptString represents, or a null string if this QScriptString is not valid.
See also toString().
Returns true if this QScriptString is not equal to other; otherwise returns false.
Assigns the other value to this QScriptString.
Returns true if this QScriptString is equal to other; otherwise returns false.
