Detailed Description

In order to minimize copying, highly optimized applications can use QConstString to provide a QString-compatible object from existing Unicode data. The Unicode data must exist for the entire lifetime of the QConstString object.

Member Function Documentation

QConstString::QConstString ( QChar * unicode, uint length )

Creates a QConstString that uses the first length Unicode characters in the array unicode. Any attempt to modify copies of the string will cause it to create a copy of the data, thus it remains forever unmodified.

QConstString::~QConstString ()

Destroys the QConstString, creating a copy of the data if other strings are still using it.

const QString& QConstString::string () const

Returns a constant string referencing the data passed during construction.
