- All Implemented Interfaces:
- Cloneable
public final 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.

SpacerRenderNode
public SpacerRenderNode()
SpacerRenderNode
public SpacerRenderNode(long width,
long height,
boolean preserve,
int spaceCount)
getNodeType
public int getNodeType()
- Specified by:
getNodeType
in class RenderNode
getSpaceCount
public int getSpaceCount()
- Returns the number of space-characters that resulted in this spacer-node. This is a content-creator hint to make
sure that the table-exports can create the represented space more easily. A space-count of zero means, that the
value is not known. In that case a renderer should apply some font-metrics magic to compute a suitable space count
from the known style information.
- Returns:
- the space count.
isEmpty
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.

isIgnorableForRendering
in class RenderNode
- Returns:
