DefaultExpandable

public DefaultExpandable(List<Row> children)

Method Detail

getChildren

public List<?> getChildren()

Description copied from interface: Expandable

Gets the list of children.

Returns:

the list of children

setChildren

public void setChildren(List<?> children)

Sets the children for this Expandable. Unless the Expandable is not added to a TreeTableModel yet, otherwise do not use this method but use AbstractExpandable.addChild(Object) instead. Nor should you use getChildren().add(...) because both setChildren and getChildren().add will not notify the TreeTableModel about the change.

Parameters:

children - the new children

preorderEnumeration

public Enumeration preorderEnumeration()

Creates and returns an enumeration that traverses the subtree rooted at this node in preorder. The first node returned by the enumeration's nextElement() method is this node.

Modifying the tree by inserting, removing, or moving a node invalidates any enumerations created before the modification.

Returns:

an enumeration for traversing the tree in preorder

See Also:

postorderEnumeration()

postorderEnumeration

public Enumeration postorderEnumeration()

Creates and returns an enumeration that traverses the subtree rooted at this node in postorder. The first node returned by the enumeration's nextElement() method is the leftmost leaf. This is the same as a depth-first traversal.

Modifying the tree by inserting, removing, or moving a node invalidates any enumerations created before the modification.

Returns:

an enumeration for traversing the tree in postorder

See Also:

depthFirstEnumeration(), preorderEnumeration()

breadthFirstEnumeration

public Enumeration breadthFirstEnumeration()

Creates and returns an enumeration that traverses the subtree rooted at this node in breadth-first order. The first node returned by the enumeration's nextElement() method is this node.

Modifying the tree by inserting, removing, or moving a node invalidates any enumerations created before the modification.

Returns:

an enumeration for traversing the tree in breadth-first order

See Also:

depthFirstEnumeration()

depthFirstEnumeration

public Enumeration depthFirstEnumeration()

Creates and returns an enumeration that traverses the subtree rooted at this node in depth-first order. The first node returned by the enumeration's nextElement() method is the leftmost leaf. This is the same as a postorder traversal.

Modifying the tree by inserting, removing, or moving a node invalidates any enumerations created before the modification.

Returns:

an enumeration for traversing the tree in depth-first order

breadthFirstEnumeration(), postorderEnumeration()
