Constructor Detail

TreeNodeAdaptor

public TreeNodeAdaptor(NodeInterface node,
                       java.lang.String name)

Constructor of TreeNodeAdaptor

Parameters:

node - a NodeInteface which is used to create the adapted node

name - the name of the TreeNodeAdaptor

TreeNodeAdaptor

public TreeNodeAdaptor(NodeInterface node)

Constructor of TreeNodeAdaptor

Parameters:

node - a NodeInteface which is used to create the adapted node

Method Detail

getNodeChildCount

public int getNodeChildCount()

getNodeChildCount() returns the number of children the curent node has.

Specified by:

getNodeChildCount in interface SimpleNodeInterface

Overrides:

getNodeChildCount in class Node

Returns:

the number of children or 0 if no children

createChildArray

public void createChildArray()

createChildArray creates an arrary of the node's children. The array is created once and used by getNodeChildren and getNodeChild.

getNodeChild

public SimpleNodeInterface getNodeChild(int i)

getNodeChild returns the child at the specified index.

Specified by:

getNodeChild in interface SimpleNodeInterface

Overrides:

getNodeChild in class Node

Parameters:

i - the 0-based index of the child to get

Returns:

the child node object (as type SimpleNodeInterface) at the specified index.

See Also:

Node.getNodeChildren(int, int), Node.setNodeChildren(com.sas.collection.StaticOrderedCollectionInterface)

getNodeChildren

public SimpleNodeInterface[] getNodeChildren(int startIndex,
                                             int count)

getNodeChildren returns the array of requested children of a node.

Specified by:

getNodeChildren in interface SimpleNodeInterface

Overrides:

getNodeChildren in class Node

Parameters:

startIndex - 0-based index which identifies the start of the range

count - the amount of children to get

Returns:

an array of child node objects (as type SimpleNodeInterface) for the specified range
