Method Detail

addNode

ITreeNode addNode()

addNode

ITreeNode addNode(int index)

addNode

ITreeNode addNode(ITreeNodeDescriptor descriptor)

addNode

ITreeNode addNode(int index,
                ITreeNodeDescriptor descriptor)

removeNode

void removeNode(ITreeNode node)

removeNode

void removeNode(int index)

removeAllNodes

void removeAllNodes()

getChildren

java.util.List<ITreeNode> getChildren()

getParentContainer

ITreeContainer getParentContainer()

setAllChildrenExpanded

void setAllChildrenExpanded(boolean expanded)

setAllChildrenExpanded

void setAllChildrenExpanded(java.lang.Integer pivotLevel,
                          boolean expanded)

Sets all children expanded or collapsed until a pivot level is reached

Parameters:

pivotLevel - The pivot level to use, assuming this node has level 0, the children level 1 and so on If expanded is true, all nodes of this level and below will be expanded If expanded is false, all node of this level and above will be collapsed If expanded is null, the expansion is unbound

expanded - If true, nodes will be expanded, I false nodes will be collapsed

Throws:

java.lang.IllegalArgumentException - if the level is not greater or equal 0

setAllChildrenChecked

void setAllChildrenChecked(boolean checked)

setAllChildrenBelowExpandedAboveCollapsed

void setAllChildrenBelowExpandedAboveCollapsed(int pivotLevel)

Expands all nodes of the given level and below and collapses all nodes above

Parameters:

pivotLevel - The pivot level, assuming this node has level 0, the children level 1 and so on

accept

boolean accept(ITreeNodeVisitor visitor)

Visits the nodes of the container by a visitor

Parameters:

visitor - The visitor to visit the nodes, must not be null

Returns:

false if the visiting should be stopped

getLevel

int getLevel()

Gets the level of the node, where 0 is the root level

Returns:

The level of the node
