Constructor Detail

InnerNode

public InnerNode()

Creates a new inner node with no children and threshold set to 0.

InnerNode

public InnerNode(java.util.ArrayList<TreeNode> children,
                 java.lang.Integer threshold)

Creates a new inner node with the given children and trreshold.

Parameters:

children - the children of this inner node

threshold - the threshold of this node

Method Detail

addChild

public void addChild(TreeNode child)

Appends a child to the children of this node.

Parameters:

child - the child to add

getChildren

public java.util.ArrayList<TreeNode> getChildren()

getNumberOfChildren

public int getNumberOfChildren()

Description copied from interface: TreeNode

Returns the number of children of this node.

Specified by:

getNumberOfChildren in interface TreeNode

getThreshold

public int getThreshold()

Description copied from interface: TreeNode

Returns the threshold value of this node. If this node is a leaf, the value must be 0.

Specified by:

getThreshold in interface TreeNode

performVisitor

public <F> F performVisitor(Visitor<F> visitor)
                     throws WrongAccessStructureException

Visits the threshold tree represented by this inner node in pre-order.

For each child, a new visitor is created via Visitor.getVisitorForNextChild() which is used to visit the child. The result of those visits are then used to calculate the result of the visitor vising this node.

Specified by:

performVisitor in interface TreeNode

Type Parameters:

F - the return result of the visitor

Parameters:

visitor - the visitor to use

Returns:

the result returned by the visitor visiting this node

Throws:

WrongAccessStructureException - if something is wrong with the access structure being traversed

setThreshold

public void setThreshold(java.lang.Integer threshold)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
