Method Detail

getChildrenComparator

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

Description copied from interface: AsyncTreeDataProvider

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

Specified by:

getChildrenComparator in interface AsyncTreeDataProvider<E extends AsyncUniqueNode>

Parameters:

node - parent node

Returns:

child nodes comparator

setChildrenComparator

public void setChildrenComparator(java.util.Comparator<E> comparator)

Sets children comparator for all nodes.

Parameters:

comparator - children comparator for all nodes

getChildrenFilter

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

Description copied from interface: AsyncTreeDataProvider

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

Specified by:

getChildrenFilter in interface AsyncTreeDataProvider<E extends AsyncUniqueNode>

Parameters:

node - parent node

Returns:

child nodes filter

setChildrenFilter

public void setChildrenFilter(com.alee.utils.compare.Filter<E> filter)

Sets children filter for all nodes.

Parameters:

filter - children filter for all nodes

isLeaf

public boolean isLeaf(E node)

Returns false by default to allow children load requests. It is recommended to override this behavior if you can easily determine whether node is leaf or not.

Specified by:

isLeaf in interface AsyncTreeDataProvider<E extends AsyncUniqueNode>

Parameters:

node - node

Returns:

false
