## org.apache.batik.ext.awt.image.rendered
Class AbstractTiledRed

    java.lang.Object
      org.apache.batik.ext.awt.image.rendered.AbstractRed
          org.apache.batik.ext.awt.image.rendered.AbstractTiledRed

All Implemented Interfaces:
  CachableRed, java.awt.image.RenderedImage, TileGenerator

Direct Known Subclasses:
  SpecularLightingRed, TileCacheRed

public abstract class AbstractTiledRed
extends AbstractRed
implements TileGenerator

This is an abstract base class that takes care of most of the normal issues surrounding the implementation of the CachableRed (RenderedImage) interface. It tries to make no assumptions about the subclass implementation.

Constructor Detail

### AbstractTiledRed

    protected AbstractTiledRed()

  void constructor. The subclass must call one of the flavors of init before the object becomes usable. This is useful when the proper parameters to the init method need to be computed in the subclasses constructor.
