public abstract class ServicePartition

extends ServiceAdapter

implements ServicePartitionMBean

Implementation of a Service Partition. Itmakes use of JMX domains in order to isolate the Services it contains. ServicePartition extensions can create their Services programmatically, through the use of metadata, or in any other manner as described in the Service. Regardless, the ServicePartition must have a domain name associated with it. If one is not explicitly assigned, then the Service's name will be used as the domain name. If the service has no name and no domain name, a ServiceException is thrown.

Method Detail

addService

public void addService(ServiceMBean service)
                throws java.lang.Exception

Add a ServiceMBean to the partitioned Services.

Specified by:

addService in interface ServicePartitionMBean

addService

public void addService(ServiceMBean service,
                       javax.management.ObjectName serviceName)
                throws java.lang.Exception

Add a ServiceMBean to the partitioned Services using the specified ObjectName for the Service.

Specified by:

addService in interface ServicePartitionMBean

removeService

public void removeService(ServiceMBean service)
                   throws java.lang.Exception

Remove a ServiceMBean from the partitioned Services

Specified by:

removeService in interface ServicePartitionMBean

removeService

public void removeService(javax.management.ObjectName objectName)
                   throws java.lang.Exception

Remove a ServiceMBean from the partitioned Services by its ObjectName

Specified by:

removeService in interface ServicePartitionMBean

iterator

public java.util.Iterator iterator()

Description copied from interface: ServicePartitionMBean

Return an iteration of these partitioned services.

Specified by:

iterator in interface ServicePartitionMBean

getServices

public java.util.Iterator getServices()

This method returns the actual instances of the registered services for this partition. This would be handy, for example, when you need to access the services directly (not via JMX).

invokeChain

protected void invokeChain(java.lang.String methodName,
                           java.lang.Object[] params,
                           java.lang.String[] types)

Invokes all of the services in the chain of services for this partition. It is assumed that the services follow an interceptor pattern where the method invoked returns a Boolean that determines whether the next service in the chain should be invoked

Parameters:

methodName - The method name

params - The parameters

types - The parameter types
