\brief The QScriptString class acts as a handle to "interned" strings in a QScriptEngine.
66
QScriptString can be used to achieve faster (repeated)
67
property getting/setting, and comparison of property names, of
70
To get a QScriptString representation of a string, pass the string
71
to QScriptEngine::toStringHandle(). The typical usage pattern is to
72
register one or more pre-defined strings when setting up your script
73
environment, then subsequently use the relevant QScriptString as
74
argument to e.g. QScriptValue::property().
76
Call the toString() function to obtain the string that a
77
QScriptString represents.
