How does qHash(QStringRef&) work?

[A Former User]

I'm curious as to how this method works. Is it just an overload that calls QStringRef::toString() (thereby making a copy of the referenced substring since this is how I'm using QStringRef) and passes that to qHash(QString&)? Or is it cleverer than that?

I'd like to use this function, so I'd like to know if it does any copying.

Thanks.

@uint qHash(const QStringRef &key)
{
return hash(key.unicode(), key.size());
}@

QStringRef::unicode()
Returns a Unicode representation of the string reference. Since the data stems directly from the referenced string, it is not null-terminated unless the string reference includes the string's null terminator.
