public interface: StateManageable [javadoc | source]

All Known Implementing Classes:
    GBeanInstance

A Java interface the meets the J2EE Management specification for a state manageable object.
Method from org.apache.geronimo.kernel.management.StateManageable Summary:
getStartTime,   getState,   getStateInstance,   start,   startRecursive,   stop
Method from org.apache.geronimo.kernel.management.StateManageable Detail:
 public long getStartTime()
    Gets the start time of this component
 public int getState()
    Gets the state of this component as an int. The int return is required by the JSR77 specification.
 public State getStateInstance()
    Gets the state of this component as a State instance.
 public  void start() throws Exception, IllegalStateException
    Transitions the component to the starting state. This method has access to the container.

    Normally a component uses this to cache data from other components. The other components will have been created at this stage, but not necessairly started and may not be ready to have methods invoked on them.

 public  void startRecursive() throws Exception, IllegalStateException
    Transitions the component to the starting state. This method has access to the container.

    If this Component is a Container, then startRecursive is called on all child Components that are in the STOPPED or FAILED state. Normally a component uses this to cache data from other components. The other components will have been created at this stage, but not necessairly started and may not be ready to have methods invoked on them.

 public  void stop() throws Exception, IllegalStateException
    Transitions the component to the stopping state. This method has access to the container.

    If this is Component is a Container, then all its child components must be in the STOPPED or FAILED State.

    Normally a component uses this to drop references to data cached in the start method. The other components will not necessairly have been stopped at this stage and may not be ready to have methods invoked on them.
