Pod::Abstract::Tree(3pm) User Contributed Perl Documentation Pod::Abstract::Tree(3pm)
NAME
Pod::Abstract::Tree - Manage a level of Pod document tree Nodes.
DESCRIPTION
Pod::Abstract::Tree keeps track of a set of Pod::Abstract::Node elements, and allows manipulation of that list of elements. Elements are
stored in an ordered set - a single node can appear once only in a single document tree, so inserting a node at a point will also remove it
from it's previous location.
This is an internal class to Pod::Abstract::Node, and should not generally be used externally.
METHODS
detach
$tree->detach($node);
Unparent the $node from $tree. All other elements will be shifted to fill the empty spot.
push
Add an element to the end of the node list.
pop
Remove an element from the end of the node list.
insert_before
$tree->insert_before($target,$node);
Insert $node before $target. Both must be children of $tree
insert_after
$tree->insert_after($target,$node);
Insert $node after $target. Both must be children of $tree
unshift
Remove the first node from the node list and return it.
Unshift takes linear time - it has to relocate every other element in id_map so that they stay in line.
children
Returns the in-order node list.
index_relative
my $node = $tree->index_relative($target, $offset);
This method will return a node at an offset of $offset (which may be negative) from this tree structure. If there is no such node, undef
will be returned. For example, an offset of 1 will give the following element of $node.
