Constructor Detail

TreeNode

public TreeNode()

Constructor.

TreeNode

public TreeNode(int size)

Constructor.

Parameters:

size - The initial size of the array containing the children.

Method Detail

getChildCount

public int getChildCount()

Description copied from interface: IASNode

Get the number of children

Specified by:

getChildCount in interface IASNode

Overrides:

getChildCount in class NodeBase

Returns:

the number of children

getChild

public IASNode getChild(int i)

Description copied from interface: IASNode

Get a particular child of this node

Specified by:

getChild in interface IASNode

Overrides:

getChild in class NodeBase

Parameters:

i - the child's index

Returns:

the specified child

replaceChild

protected void replaceChild(NodeBase child,
                NodeBase target)

Description copied from class: NodeBase

Replaces the child with the given target. The child will be removed from the tree, and its parentage will be updated

Overrides:

replaceChild in class NodeBase

Parameters:

child - the NodeBase to replace

target - the NodeBase to replace the replaced

swapChildren

protected void swapChildren(NodeBase child,
                NodeBase target)

Description copied from class: NodeBase

Changes the position of two children in our tree. Neither child can be null and both must have the same parent

Overrides:

swapChildren in class NodeBase

Parameters:

child - the child to replace target

target - the child to replace child

normalize

public void normalize(boolean fillInOffsets)

Description copied from class: NodeBase

Normalize the tree. Move custom children into the real child list and fill in missing offsets so that offset lookup will work. Used during parsing.

Overrides:

normalize in class NodeBase

getInitialChildCount

protected int getInitialChildCount()

Take a guess as to an efficient initial child count. We can override this in nodes that have a fixed number of children.

Returns:

initial size to use when creating children

addChild

public void addChild(NodeBase child)

Add the node as a child. Used during parsing.

Parameters:

child - child node to add

addChild

public void addChild(NodeBase child,
            int position)

addChildPostNormalize

protected void addChildPostNormalize(NodeBase child)

Add the node as a child after normalization has occurred. Used after parsing.

Parameters:

child - child node to add

addChildInOrder

protected void addChildInOrder(NodeBase newChild,
                   boolean fillInOffsets)

Add the node as a child, making sure it's in offset order with the other children. This adds children from back to front, so it's most efficient to add the children in order. Used during parsing.

Parameters:

newChild - child node to add

fillInOffsets - true if we should fill in offsets as we go

addTemporaryChild

protected void addTemporaryChild(NodeBase child)

Adds a node to the list of children WITHOUT changing their real parent.

Parameters:

child - new child node

removeChild

protected void removeChild(NodeBase child)

Remove the node as a child. Used during parsing.

Parameters:

child - child node to remove

removeTemporaryChild

protected void removeTemporaryChild(NodeBase child)

Removes a node from the list of children WITHOUT changing their real parent.

Parameters:

child - new child node

removeAllChildren

public void removeAllChildren()

Removes all of the children of this node

optimizeChildren

protected void optimizeChildren(Object newChildren)

Sets our children to an optimized version of newChildren.

Parameters:

newChildren -

sortChildren

protected void sortChildren(boolean updateBounds)
