Functions

clearMap()

void QDomNamedNodeMapPrivate::clearMap

(

)

Remove all children from the map.

Definition at line 3134 of file qdom.cpp.

{
    // Dereference all of our children if we took references
    if (!appendToParent) {
        QHash<QString, QDomNodePrivate *>::const_iterator it = map.constBegin();
        for (; it != map.constEnd(); ++it)
            if (!(*it)->ref.deref())
                delete *it;
    }
    map.clear();
}

clone()

QDomNamedNodeMapPrivate * QDomNamedNodeMapPrivate::clone

(

QDomNodePrivate *

parent

)

Creates a copy of the map. It is a deep copy that means that all children are cloned.

setAppendToParent()

void QDomNamedNodeMapPrivate::setAppendToParent ( bool  b )

inline

If true, then the node will redirect insert/remove calls to its parent by calling QDomNodePrivate::appendChild or removeChild. In addition the map wont increase or decrease the reference count of the nodes it contains.

By default this value is false and the map will handle reference counting by itself.
