PrecomputeNodeImpl (flow-engine JavaDoc)

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.
