Method Summary

double	getDist() Returns the distance between the two children nodes on the next level.
DendrogramNode	getFirstSubnode() Returns the first sub-node of this node.
DataRow	getLeafDataPoint() Returns the DataRow associated with a leaf node.
double	getMaxDistance() Returns the maximum distance from this node to any of the leafs.
DendrogramNode	getSecondSubnode() Returns the second sub-node of this node.
boolean	isLeaf() Returns if this node is a leaf.

Method Detail

getFirstSubnode

DendrogramNode getFirstSubnode()

Returns the first sub-node of this node. This method is implemented because of the binary characteristic of this tree.

Returns:

the first sub node

getDist

double getDist()

Returns the distance between the two children nodes on the next level. Must return 0 for leaf nodes.

Returns:

the distance to the next level.

isLeaf

boolean isLeaf()

Returns if this node is a leaf.

Returns:

true if the node is a leaf node, false otherwise

getMaxDistance

double getMaxDistance()

Returns the maximum distance from this node to any of the leafs. Must be 0 for leaf nodes.

Returns:

the maximum distance to a leaf node

getLeafDataPoint

DataRow getLeafDataPoint()

Returns the DataRow associated with a leaf node.

Returns:

the leaf data point or null if this node is not a leaf

getSecondSubnode

DendrogramNode getSecondSubnode()

Returns the second sub-node of this node. This method is implemented because of the binary characteristic of this tree.

Returns:

the second sub node
