public void accept(SEShowVisitor visitor)
SENode
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.

public void postProcess(ShowBuilder builder) throws java.io.IOException
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.
