| addTreeDataListener | | public void addTreeDataListener(TreeDataListener l)(Code) | | Add a listener to the tree that's notified each time a change to the data model occurs
Parameters:
l - the listener to add |
| getChild | | public Object getChild(Object parent, int index)(Code) | | Returns the child of parent at index index in the parent's child array.
Parameters:
parent - a node in the tree, obtained from this data source the child of parent at index index |
| getChildCount | | public int getChildCount(Object parent)(Code) | | Returns the number of children of parent.
Parameters:
parent - a node in the tree, obtained from this data source the number of children of the node parent |
| getPath | | public int[] getPath(Object parent, Object lastNode)(Code) | | Returns an integer array to represent the path from parent(exclusive) to lastNode(inclusive).
notice:
The path has to be in "parent" to "lastNode" order
Ex: {1,0,2}
1. Go to the parent's child at index(1);
2. Go to the index(1)'s child at index(0);
3. Go to the index(0)'s child at idnex(2) -- the lastNode;
If parent is the same as lastNode, return null or empty array.
Parameters:
parent - the origin of Path
Parameters:
lastNode - the destination of Path an integer array to represent the path from parent to lastNode. |
| getRoot | | public Object getRoot()(Code) | | Returns the root of the tree.
the root of Tree. |
| isLeaf | | public boolean isLeaf(Object node)(Code) | | Returns true if node is a leaf.
Parameters:
node - a node in the tree, obtained from this data source true if node is a leafs |
| removeTreeDataListener | | public void removeTreeDataListener(TreeDataListener l)(Code) | | Remove a listener to the tree that's notified each time a change to the data model occurs
Parameters:
