Class FoldLargeNodes

  +--ca.quine.jcommons.freemind.maputil.FoldLargeNodes

All Implemented Interfaces:

INodeApplicator

public class FoldLargeNodes

extends Object

implements INodeApplicator

Fold (close) nodes with more than the given number of child nodes. If a node is already folded, then we "trim" the tree (that is, we do not descend on the node's children). A parent node with (say) three children, where all of them are folded, has a count of three regardless of how many children the folded nodes have. This implementation is not used by MapUtils for MapUtils.closeLargeNodes(Map, int). It is provided as an example of how "trimming" a tree can be useful (that is, returning INodeApplicator.SEARCH_TRIM from the apply method).
