org.pentaho.reporting.engine.classic.core.layout
Class StreamingRenderer

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

All Implemented Interfaces:

Cloneable, Renderer

public class StreamingRenderer
extends AbstractRenderer

The streaming renderer streams all generated (and layouted) elements to the output processor. The output processor should mark the processed elements by setting the 'dirty' flag to false. Pagebreaks will be ignored, all content ends up in a single stream of data.
