Class AbstractLayoutManager

java.lang.Object
  ar.com.fdvs.dj.core.layout.AbstractLayoutManager

All Implemented Interfaces:

LayoutManager

Direct Known Subclasses:

ClassicLayoutManager, ListLayoutManager

public abstract class AbstractLayoutManager
extends java.lang.Object
implements LayoutManager

Abstract Class used as base for the different Layout Managers.

A Layout Manager is always invoked after the entities registration stage.
A subclass should be created whenever we want to give the users the chance to
easily apply global layout changes to their reports. Example: Ignore groups
and styles for an Excel optimized report.
