contains

public boolean contains(AgentListener listener)

inheritedBySubagents

public boolean inheritedBySubagents()

Description copied from interface: AgentListener

Indicates whether this listener should be used only to the agent where it is registered (default) or also inherited by its subagents.

Specified by:

inheritedBySubagents in interface AgentListener

Returns:

true if the listener should be inherited by sub-agents, false otherwise

compose

public static AgentListener compose(AgentListener existingListener,
 AgentListener newListener)

Composes a newly registered listener with the existing one, if any. When the existing listener is already a ComposedAgentListener, the new listener is added to it.

Returns:

the listener to be used in place of the existing one

composeWithInherited

public static AgentListener composeWithInherited(AgentListener localListener,
 AgentListener parentListener)

listenerOfType

public static <T extends AgentListener> T listenerOfType(AgentListener rootListener,
 Class<T> listenerType)
