Field Detail

SEPARATOR

public static final java.lang.String SEPARATOR
Separator char to be used in node path generation.

Method Detail

getNode

public TreeNode getNode()

nodeId - The id of the node to set

getPathInformation

public java.lang.String[] getPathInformation(java.lang.String nodeId)
Gets an array of String containing the ID's of all of the TreeNodes in the path to the specified node. The path information will be an array of String objects representing node ID's. The array will starting with the ID of the root node and end with the ID of the specified node.

public boolean isLastChild(java.lang.String nodeId)
Indicates whether or not the specified TreeNode is the last child in the List of children. If the node id provided corresponds to the root node, this returns true.

Parameters:
nodeId - The ID of the node to check
Returns:
boolean

setTreeState

public void setTreeState(TreeState state)

getTreeState

public TreeState getTreeState()
