Class PrecomputeNodeImpl

java.lang.Object

org.jfree.report.data.PrecomputeNodeImpl

All Implemented Interfaces:

PrecomputeNode

public class PrecomputeNodeImpl
extends java.lang.Object
implements PrecomputeNode

A precompute-node represents a resolved element or section of the report definition. Unlike the structural nodes, these nodes can always have childs.

The resulting tree gets pruned as early as possible - nodes which do not contain precomputed or preserved expressions will not be stored.
