All Implemented Interfaces:

Serializable, JRRenderable, Renderable

Enclosing class:

JRVirtualPrintPage

public static class JRVirtualPrintPage.JRIdHolderRenderer
extends Object
implements Renderable

Dummy image renderer that only stores the ID of a cached renderer. When a page gets serialized, all image renderers that are cached in the virtualization context are replaced with dummy renderers that only store the ID. When a page gets deserialized, the original renderers are restored from the virtualization context based on the ID.
