Detailed Description
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.

Constructor & Destructor Documentation
| QScriptString::QScriptString | ( | ) |
Constructs an invalid QScriptString.
| QScriptString::QScriptString | ( | const QScriptString & | other | ) |
Constructs a new QScriptString that is a copy of other.
| QScriptString::~QScriptString | ( | ) |
Destroys this QScriptString.
Method Documentation
| bool QScriptString::isValid | ( | ) | const |
Returns true if this QScriptString is valid, otherwise returns false.
| QScriptString::operator QString | ( | ) | const |
Returns the string that this QScriptString represents, or a null string if this QScriptString is not valid.

- toString()
| bool QScriptString::operator!= | ( | const QScriptString & | other | ) | const |
Returns true if this QScriptString is not equal to other, otherwise returns false.
| QScriptString & QScriptString::operator= | ( | const QScriptString & | other | ) |
Assigns the other value to this QScriptString.
| bool QScriptString::operator== | ( | const QScriptString & | other | ) | const |
Returns true if this QScriptString is equal to other, otherwise returns false.
| quint32 QScriptString::toArrayIndex | ( | bool * | ok = nullptr | ) | const |
Attempts to convert this QScriptString to a CsScript array index, and returns the result. If a conversion error occurs ok is set to false otherwise ok is set to true.
