Method Summary

Methods

Modifier and Type	Method and Description
String	getComponentId() Returns id of the agent - unique across the JVMs.
String	getName() Returns human readable name.
ObjectName	getObjectName(String domain) Returns JMX object name of the MBean.
IAgentState	getState() Returns the state of the agent (whether it's running / dead / etc.).
void	kill() Stops the agent (unconditionally), closing whatever connection it may have, this method must be non-blocking + interrupting all the communication, logic or whatever threads the agent may have.
void	pause() This should pause the the agent.
void	resume() This should resume the logic of the agent.
void	start() Attempt to launch the agent.
void	stop() Attempt to stop the agent, usually meaning dropping all running flags and see whether it will stop automatically.

Method Detail

getObjectName

ObjectName getObjectName(String domain)
                         throws MalformedObjectNameException

Returns JMX object name of the MBean.

Parameters:

domain - jmx domain

Returns:

name under which the MBean should be exported

Throws:

MalformedObjectNameException

getComponentId

String getComponentId()

Returns id of the agent - unique across the JVMs.

Returns:

getName

String getName()

Returns human readable name. getDisplayName is set by agent and doesn't have to be unique, while getName is machine assigned and is unique.

getState

IAgentState getState()

Returns the state of the agent (whether it's running / dead / etc.).

Note that the type AgentState wraps two things:

• AgentStateType that describes the type of the state (init, running, paused, etc.)
• String description of the state

Returns:

start

void start()
           throws AgentException

Attempt to launch the agent. If it does not throw an exception, agent has been successfully started, also the state of the agent state is changed into Running state.

Throws:

AgentException

pause

void pause()
           throws AgentException

This should pause the the agent. If it does not throw an exception, agent has been successfully started, also the state of the agent state is changed into Paused state.

If your agent can't be paused, throw OperationNotSupportedException.

Throws:

AgentException

resume

void resume()
            throws AgentException

This should resume the logic of the agent. If it does not throw an exception, agent has been successfully resumed, also the state of the agent state is changed into Running state.

If your agent can't be paused therefore can't be resumed, throw OperationNotSupportedException.

Throws:

AgentException

stop

void stop()
          throws AgentException

Attempt to stop the agent, usually meaning dropping all running flags and see whether it will stop automatically. This method may be blocking. If it does not throw the exception, the agent has been successfully stopped, also the state of the agent is changed into End state.

If the stop can not complete - it must automatically call kill() method.

Throws:

AgentException

kill

void kill()

Stops the agent (unconditionally), closing whatever connection it may have, this method must be non-blocking + interrupting all the communication, logic or whatever threads the agent may have.

After calling kill() method, the only method that may be called is getState() to examine state of the agent.

This also equals to "exception happened outside the agent" and "IFatalErrorEvent should be propagated inside the agent"
