Class FlowRenderer

java.lang.Object
  org.pentaho.reporting.engine.classic.core.layout.AbstractRenderer
      org.pentaho.reporting.engine.classic.core.layout.FlowRenderer

All Implemented Interfaces:

Cloneable, Renderer

public class FlowRenderer
extends AbstractRenderer

A flow renderer is a light-weight paginating renderer. It does not care about the page-size but searches for manual breaks. Once a manual break is encountered, the flow shifts and creates a page-event. (This is the behavior of the old table-exporters.)

This implementation is a mix of a paginated and streaming renderer.
