UniConfChangeTree * UniConfTree< UniConfChangeTree >::parent | ( | ) | const [inline, inherited] |
Returns a pointer to the parent node, or NULL if there is none.

References UniHashTreeBase::xparent.
void UniConfTree< UniConfChangeTree >::setparent | ( | UniConfChangeTree * | parent | ) | [inline, inherited] |
Reparents this node.
Definition at line 44 of file uniconftree.h.
UniConfChangeTree * UniConfTree< UniConfChangeTree >::root | ( | ) | const [inline, inherited] |
Returns a pointer to the root node of the tree.

UniConfKey UniConfTree< UniConfChangeTree >::fullkey | ( | const UniConfChangeTree * | ancestor = NULL | ) | const [inline, inherited] |
Returns full path of this node relative to an ancestor.
If ancestor is NULL, returns the root.

UniConfChangeTree * UniConfTree< UniConfChangeTree >::find | ( | const UniConfKey & | key | ) | const [inline, inherited] |
Finds the sub-node with the specified key.
If key.isempty(), returns this node.

UniConfChangeTree * UniConfTree< UniConfChangeTree >::findchild | ( | const UniConfKey & | key | ) | const [inline, inherited] |
Finds the direct child node with the specified key.
If key.numsegments() == 1, then performs the same task as find(key), but a little faster. Otherwise returns NULL.

void UniConfTree< UniConfChangeTree >::remove | ( | const UniConfKey & | key | ) | [inline, inherited] |
Removes the node for the specified key from the tree and deletes it along with any of its children.
If the key is UniConfKey::EMPTY, deletes this object.

bool UniConfTree< UniConfChangeTree >::compare | ( | const UniConfChangeTree * | other, |
