public class TreeNode

extends java.lang.Object

An instance of TreeNode characterizes a partition of a multidimensional dataset. It is extracted from metadata that results from a mining (training) run. This information forms part of a rule that can be used to construct a human interpretable view of factors that correlate to the target. Its ancester nodes contain the set of predicates that form a sub-rule that classifies the rows of a dataset as being in or not in the node. Its predicate, if any, define its child nodes. Nodes without children are called leaves. The set of leaves in the selected subtree form the decision tree's final partitioning of the multidimensional data. In addition, a treenode may contain a score distribution, which characterizes the distribution of data at that node with respect to a reference dataset.
