Class SpacerRenderNode

java.lang.Object

org.jfree.layouting.renderer.model.RenderNode

org.jfree.layouting.renderer.model.SpacerRenderNode

All Implemented Interfaces:

java.lang.Cloneable

Direct Known Subclasses:

TableColumnNode

public class SpacerRenderNode
extends RenderNode

A spacer reserves space for whitespaces found in the text. When encountered at the beginning or end of lines, it gets removed.

Spacers are always considered discardable, so when encountered alone, they will get pruned.

public boolean isEmpty()

Overrides:

isEmpty in class RenderNode

isDiscardable

public boolean isDiscardable()

Overrides:

isDiscardable in class RenderNode

isIgnorableForRendering

public boolean isIgnorableForRendering()

If that method returns true, the element will not be used for rendering. For the purpose of computing sizes or performing the layouting (in the validate() step), this element will treated as if it is not there.

If the element reports itself as non-empty, however, it will affect the margin computation.

Overrides:

isIgnorableForRendering in class RenderNode

Returns:
