Detailed DescriptionThe 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. Member Function DocumentationQScriptString::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. bool QScriptString::isValid () constReturns true if this QScriptString is valid; otherwise returns false. quint32 QScriptString::toArrayIndex ( bool * ok = 0 ) constAttempts to convert this QScriptString to a QtScript 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. QString QScriptString::toString () constReturns the string that this QScriptString represents, or a null string if this QScriptString is not valid. See also isValid(). QScriptString::operator QString () constReturns the string that this QScriptString represents, or a null string if this QScriptString is not valid. See also toString(). bool QScriptString::operator!= ( const QScriptString & other ) constReturns 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 ) constReturns true if this QScriptString is equal to other; otherwise returns false.
