boolean	isLeaf(E node) Returns whether the specified node is leaf (doesn't have any children) or not.

Method Detail

getRoot

E getRoot()

Returns asynchronous tree root node. This request uses the EDT and should be processed quickly.

Returns:

root node

getChildren

java.util.List<E> getChildren(E node)

Returns child nodes for the specified asynchronous tree node.

Parameters:

node - parent node

Returns:

child nodes list

getChildrenComparator

java.util.Comparator<E> getChildrenComparator(E node)

Returns child nodes comparator for the specified asynchronous tree node. No sorting applied to children in case null is returned.

Parameters:

node - parent node

Returns:

child nodes comparator

getChildrenFilter

com.alee.utils.compare.Filter<E> getChildrenFilter(E node)

Returns child nodes filter for the specified asynchronous tree node. No filtering applied to children in case null is returned.

Parameters:

node - parent node

Returns:

child nodes filter

isLeaf

boolean isLeaf(E node)

Returns whether the specified node is leaf (doesn't have any children) or not. If you are not sure if the node is leaf or not - simply return false, that will allow the tree to expand this node on request.

Parameters:

node - node

Returns:

true if the specified node is leaf, false otherwise
