Interface XAStatefulHolder

All Known Subinterfaces:

XAResourceHolder

All Known Implementing Classes:

AbstractXAResourceHolder, AbstractXAStatefulHolder, DualSessionWrapper, EhCacheXAResourceHolder, JdbcPooledConnection, JmsPooledConnection, RecoveryXAResourceHolder

public interface XAStatefulHolder

Any pooled connection class must implement the XAStatefulHolder interface. It defines all the services that must be implemented by the connection as well as the pooling lifecycle states. Instances of this interface have to create and manage XAResourceHolders.

Method Detail

getState

int getState()

Get the current resource state.

This method is thread-safe.

Returns:

the current resource state.

setState

void setState(int state)

Set the current resource state.

This method is thread-safe.

Parameters:

state - the current resource state.

addStateChangeEventListener

void addStateChangeEventListener(StateChangeListener listener)

Register an implementation of StateChangeListener.

Parameters:

listener - the StateChangeListener implementation to register.

removeStateChangeEventListener

void removeStateChangeEventListener(StateChangeListener listener)

Unregister an implementation of StateChangeListener.

Parameters:

listener - the StateChangeListener implementation to unregister.

getXAResourceHolders

java.util.List<XAResourceHolder> getXAResourceHolders()

Get the list of XAResourceHolders created by this XAStatefulHolder that are still open.

This method is thread-safe.

Returns:

the list of XAResourceHolders created by this XAStatefulHolder that are still open.

getConnectionHandle

java.lang.Object getConnectionHandle()
                              throws java.lang.Exception

Create a disposable handler used to drive a pooled instance of XAStatefulHolder.

This method is thread-safe.

Returns:

a resource-specific disaposable connection object.

Throws:

java.lang.Exception - a resource-specific exception thrown when the disaposable connection cannot be created.

close

void close()
    throws java.lang.Exception

Close the physical connection that this XAStatefulHolder represents.

Throws:

java.lang.Exception - a resource-specific exception thrown when there is an error closing the physical connection.

getLastReleaseDate

java.util.Date getLastReleaseDate()

Get the date at which this object was last released to the pool. This is required to check if it is eligible for discard when the containing pool needs to shrink.

Returns:

the date at which this object was last released to the pool or null if it never left the pool.
