Constructor Detail


public SESetTarget(SEShow show,
                   java.lang.String name,
                   int target)
Create a new SetTarget node.

show - The show we're a part of
name - The name of this node
target - The target of the RenderContext for our children to use.


public SESetTarget(SEShow show)
Method Detail


public int getTarget()
Internal use only.


public void setTarget(int target)
Internal use only.


public void writeInstanceData(GrinDataOutputStream out)
Description copied from interface: SENode
Record this node information to the binary file format. An implementation of this method is recommended to call out.writeSuperClassData(this) as the first line of the method to write out data defined in the base class of this Node type.

Specified by:
writeInstanceData in interface SENode
out - The stream to write out.
Throws: - if error occurs.
See Also:
GrinDataOutputStream.writeSuperClassData(Feature), GrinDataOutputStream.writeSuperClassData(RCHandler), GrinDataOutputStream.writeSuperClassData(Segment), GrinDataOutputStream.writeSuperClassData(Command)


public java.lang.String getRuntimeClassName()
Description copied from interface: SENode
Returns the class that should be constructed at Show runtime to represent this SENode.

Specified by:
getRuntimeClassName in interface SENode
String A fully qualified classname of a Node at xlet runtime.


public void accept(SEShowVisitor visitor)
Description copied from interface: SENode
Calls the visit method corresponding to this node type.

If you are defining a user-defined feature, there are some restrictions that you'll want to follow. If your extension is a feature that has children, then you should make it a subclass of one of the built-in feature types, Assembly, Modifer or Group. That's because the GRIN compiler defines visitors that need to visit every node in the tree, but these built-in visitors don't know about your extension types. By making your extension type a subclass of one of the standard ones, and by making your accept() method call either visitAssembly(), visitGroup() or visitUserDefinedModifier(), as appropriate, you'll ensure that all the children get visited.

Specified by:
accept in interface SENode
visitor - SEShowVisitor object.

public void postProcess(ShowBuilder builder)
Do any needed post-processing in this show. The grin compiler works as follows:

During the post-process phase, a node can add new features to the show, by calling ShowBuilder.addSyntheticFeature(), and it can insert a new feature as the parent of a given feature, by calling ShowBuilder.injectParent(). It can also add segments and handlers by calling the appropriate builder methods.

When a parent is injected, the ShowBuilder calls postProcess() on all nodes automatically, including nodes that are created during the execution of postProcess() in another node.

Specified by:
postProcess in interface SENode
builder - The builder that holds state for the show
Throws: - if an error is encountered
See Also:
ShowBuilder.addSyntheticFeature(Feature), ShowBuilder.injectParent(Feature, Feature)


public void changeFeatureReference(Feature from,
                                   Feature to)
Change a feature reference from one feature to a new one. If your node has a reference to the feature from, it should be changed to refer to to. This is called for every node in an SEShow when SENode.injectParent is used.

The ShowBuilder calls changeFeatureReference() on all nodes automatically, including nodes that are created during the execution of postProcess().

Specified by:
changeFeatureReference in interface SENode
See Also:
SENode.changeFeatureReference(Feature, Feature)


public void scaleBy(int xScale,
                    int yScale,
                    int xOffset,
                    int yOffset)
Scale this node by the given scale factor, and apply the given offset. This will change the size of the features and RC handlers within the show at compile time, so no special scaling action is required at runtime.

Specified by:
scaleBy in interface SEScalableNode
xScale - x scale factor in mills
yScale - y scale factor in mills
xOffset - x offset in pixels
yOffset - y offset in pixels


public java.lang.String toString()

toString in class Feature
a developer-friendly description of this feature, for debugging
