semanticEventBefore
public boolean semanticEventBefore(SemanticEvent se,
java.lang.String msg)
- Description copied from class:
Behavior
- Round robin distribution to all behaviors.
Message and clientData unpacked from SemanticEvent for convenience.
Message is interned, so if you compare to a literal, you can use "==".
Message can't be changed (it can be short-circuited out of), but client data can be mutated as it is passed along (so it's not passed as a parameter).
- Overrides:

restore
public void restore(ESISNode n,
java.util.Map<java.lang.String,java.lang.Object> attr,
Layer layer)
- Description copied from class:
Behavior
- Takes the place of a constructor's initialization functions; that is, it is invoked exactly once immediately after object instantiation.
When restored from hub, passed XML content subtree if any as first parameter and attributes from XML tag's attributes.
This protocol cannot be short-circuited.

paintAfter
public boolean paintAfter(Context cx,
Node node)
- Description copied from class:
Behavior
- A tree walk protocol, called before observed node has been painted.
Called in same coordinate space as node's painting.
Use to draw annotations at node's location.
For instance, Search uses this to decorate the scrollbar (a type of node) with location of matches.
- Overrides:
paintAfter
