NAME

JSON::JOM::Plugins::TreeUtils - add tree methods

DESCRIPTION

This JOM plugin adds the following method to JOM objects and arrays:

• hasDescendent($x) - returns true if $x is a descendent of the current node.

• hasChild($x) - returns true if $x is a direct child of the current node. This should be faster than looping through values.

• getDescendentsByType($type) - list of descendent nodes where typeof is $type. $type may be '*'. Returns results in depth-first order.

• getChildrenByType($type) - list of child nodes where typeof is $type. $type may be '*'.

It adds the following method to all JOM nodes:

• hasAncestor($x) - returns true if $x is an ancestor of the current node.
