Method Detail

init

public void init(AgentContainer ac,
                 Profile p)
          throws ProfileException

Description copied from interface: Service

Performs the passive initialization step of the service. This method is called before activating the service. Its role should be simply the one of a constructor, setting up the internal data as needed. Service implementations should not use the Service Manager and Service Finder facilities from within this method. A distributed initialization protocol, if needed, should be exectuted within the boot() method.

Specified by:

init in interface Service

Overrides:

init in class BaseService

Parameters:

ac - The agent container this service is activated on.

p - The configuration profile for this service.

Throws:

ProfileException - If the given profile is not valid.

boot

public void boot(Profile p)
          throws ServiceException

Description copied from interface: Service

Performs the active initialization step of a kernel-level service. When JADE kernel calls this method, the service has already been already associated with its container and registered with the Service Manager.

Specified by:

boot in interface Service

Overrides:

boot in class BaseService

Parameters:

p - The configuration profile for this service.

Throws:

ServiceException - If a problem occurs during service initialization.

shutdown

public void shutdown()

Description copied from interface: Service

Performs the shutdown step of a kernel-level service. The JADE kernel calls this method just before uninstalling this service

Specified by:

shutdown in interface Service

Overrides:

shutdown in class BaseService

getName

public String getName()

Description copied from interface: Service

Retrieve the name of this service, that can be used to look up its slices in the Service Finder.

Returns:

The name of this service.

ServiceFinder

getHorizontalInterface

public Class getHorizontalInterface()

Description copied from class: BaseService

This should be properly implemented by the services that have non-empty slices.

Specified by:

getHorizontalInterface in interface Service

Overrides:

getHorizontalInterface in class BaseService

Returns:

A Class object, representing the interface that is implemented by the slices of this service. Let s be the Class object corresponding to the Service.Slice interface, and let c be the returned Class object. Then, the two following conditions must hold:

1. c.isInterface() == true
2. s.isAssignableFrom(c) == true

getLocalSlice

public Service.Slice getLocalSlice()

Description copied from class: BaseService

This should be properly implemented by the services that have non-empty slices.

Specified by:

getLocalSlice in interface Service

Overrides:

getLocalSlice in class BaseService

Returns:

The slice of this service that resides on the local platform node, or null if no such slice exists.

getHelper

public ServiceHelper getHelper(Agent a)

Description copied from class: BaseService

This should be properly implemented by the services that have helpers.

Specified by:

getHelper in interface Service

Overrides:

getHelper in class BaseService

Parameters:

a - The agent which the helper is requested for.

Returns:

The ServiceHelper to be used by the agent.
