List<Integer>	expandAll()	Expands all tree nodes.
List<Integer>	expandToLevel(int level)	Expands all tree nodes to a certain level.
List<Integer>	expandToLevel(int parentIndex, int level)	Expands the tree node at the given index to a certain level.

GlazedListTreeRowModel

public GlazedListTreeRowModel(GlazedListTreeData<T> treeData)

Method Detail

isCollapsed

public boolean isCollapsed(int index)

Note: The check only works for visible elements, therefore a check for an element that is below an collapsed element does not work.

Parameters:

index - The index of the tree element to check.

Returns:

true if the children of the tree node at the given index are visible, false if not.

collapse

public List<Integer> collapse(int index)

Collapse the tree node at the given visible index.

Parameters:

index - The index of the node in the collection that should be collapsed.

Returns:

Returns an empty list because the list transformation for expand/collapse is handled by GlazedLists TreeList.

collapseAll

public List<Integer> collapseAll()

Will check the whole TreeList for its nodes and collapses them if they are expanded. After executing this method, all nodes in the TreeList will be collapsed.

Returns:

Returns an empty list because the list transformation for expand/collapse is handled by GlazedLists TreeList.

expand

public List<Integer> expand(int index)

Expand the tree node at the given visible index.

Parameters:

index - The index of the node in the collection that should be expanded.

Returns:

Returns an empty list because the list transformation for expand/collapse is handled by GlazedLists TreeList.

expandToLevel

public List<Integer> expandToLevel(int parentIndex,
                                   int level)

Description copied from interface: ITreeRowModel

Expands the tree node at the given index to a certain level.

Parameters:

parentIndex - The index of the node in the collection that should be expanded.

level - The level to which the tree node should be expanded.

Returns:

The indexes of all children that are showed after the expand operation is performed.

internalExpandToLevel

protected void internalExpandToLevel(int parentIndex,
                                     int level)

Performs the expand operations iteratively without notifying the listeners while processing.

Parameters:

parentIndex - The index of the node in the collection that should be expanded.

level - The level to which the tree nodes should be expanded.

expandAll

public List<Integer> expandAll()

Expands all tree nodes.

Returns:

Returns an empty list because the list transformation for expand/collapse is handled by GlazedLists TreeList.

internalExpandAll

protected void internalExpandAll()

Performs the expand operations iteratively without notifying the listeners while processing.

expandToLevel

public List<Integer> expandToLevel(int level)

Expands all tree nodes to a certain level.

Parameters:

level - The level to which the tree nodes should be expanded.

Returns:

Returns an empty list because the list transformation for expand/collapse is handled by GlazedLists TreeList.

internalExpandToLevel

protected void internalExpandToLevel(int level)

Performs the expand operations iteratively without notifying the listeners while processing.

Parameters:

level - The level to which the tree nodes should be expanded.

getTreeData

public GlazedListTreeData<T> getTreeData()

Returns the ITreeData that is backed by this tree row model.

Overrides:

getTreeData in class AbstractTreeRowModel<T>

Returns:

The ITreeData that is backed by this tree row model.
