Method Detail

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:

semanticEventAfter

public boolean semanticEventAfter(SemanticEvent se,
                                  java.lang.String msg)

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.
