public abstract class RenderNode extends java.lang.Object implements java.lang.Cloneable
A node of the rendering model. The renderer model keeps track of the rendering state - what has already been rendered, what is pending, etc. Things that have been rendered completely get removed from the model. The default model makes some assumptions about the node processing:- Once placed somewhere, nodes will never move anywhere else
- Once size computation is complete, nodes will not be modified anymore.

clone
public java.lang.Object clone()
Clones this node. Be aware that cloning can get you into deep trouble, as the relations this node has may no longer be valid.- Overrides:
clone
in classjava.lang.Object
- Returns:
-
derive
public RenderNode derive(boolean deep)
Derive creates a disconnected node that shares all the properties of the original node. The derived node will no longer have any parent, silbling, child or any other relationships with other nodes.- Returns:
-
hibernate
public RenderNode hibernate()
Derives an hibernation copy. The resulting object should get stripped of all unnecessary caching information and all objects, which will be regenerated when the layouting restarts. Size does matter here.- Returns:
-
deriveFrozen
public RenderNode deriveFrozen(boolean deep)
-
isFrozen
public boolean isFrozen()
-
isHibernated
public boolean isHibernated()
-
setHibernated
protected void setHibernated(boolean hibernated)
-
findNodeById
public RenderNode findNodeById(java.lang.Object instanceId)
-
isOpen
public boolean isOpen()
-
isEmpty
public boolean isEmpty()
-
getParentBlockContext
public RenderBox getParentBlockContext()
-
isDiscardable
public boolean isDiscardable()
-
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.- Returns:
-
getNodeLayoutProperties
public NodeLayoutProperties getNodeLayoutProperties()
Returns the baseline info for the given node. This can be null, if the node does not have any baseline info at all. If the element has more than one set of baselines, the baseline of the first element is returned.- Returns:
-
freeze

-
isDirectionLTR
