                         int index,
                         Object[] arguments)

                         Object id,
                         int index,

                         Object[] arguments,
                         EJBInstanceContext instanceContext)

Method Detail

getMethodIndex

public int getMethodIndex()

Description copied from interface: EJBInvocation

The index of the virtual EJB operation

Specified by:

getMethodIndex in interface EJBInvocation

Returns:

the index of the EJB operation being performed

getType

public EJBInterfaceType getType()

Description copied from interface: EJBInvocation

The type of invocation, indicating which interface was invoked or which 'special' callback was should be invoked (e.g. ejbTimeout).

Specified by:

getType in interface EJBInvocation

Returns:

the type of invocation

getArguments

public Object[] getArguments()

Description copied from interface: EJBInvocation

Any arguments to the invocation (e.g. Method parameters).

Specified by:

getArguments in interface EJBInvocation

Returns:

the arguments to the invocation; null indicates no arguments (equivalent to Object[0])

getId

public Object getId()

Description copied from interface: EJBInvocation

The identity of the instance being invoked; for example, the primary key of an Entity EJB.

Specified by:

getId in interface EJBInvocation

Returns:

the identity of the instance to invoke; may be null for 'class' level operations

getEJBInstanceContext

public EJBInstanceContext getEJBInstanceContext()

Description copied from interface: EJBInvocation

The context representing the actual instance to use for processing this request. Is transient, not valid on the client side, and will not be valid on the server side until a suitable instance has been located by an Interceptor

Specified by:

getEJBInstanceContext in interface EJBInvocation

Returns:

the context representing the instance to invoke

setEJBInstanceContext

public void setEJBInstanceContext(EJBInstanceContext instanceContext)

Description copied from interface: EJBInvocation

Set the instance context to use

Specified by:

setEJBInstanceContext in interface EJBInvocation

Parameters:

instanceContext - the instance context to use

getTransactionContext

public org.apache.geronimo.transaction.context.TransactionContext getTransactionContext()

Description copied from interface: EJBInvocation

Gets the transaction context to use. Eventhough the tx context is available from a thread local we carry it in the invocation context to avoid the extra tx cost.

Specified by:

getTransactionContext in interface EJBInvocation

Returns:

the transaction context to use

setTransactionContext

public void setTransactionContext(org.apache.geronimo.transaction.context.TransactionContext transactionContext)

Description copied from interface: EJBInvocation

Setx the transaction context to use. Eventhough the tx context is available from a thread local we carry it in the invocation context to avoid the extra tx cost.

Specified by:

setTransactionContext in interface EJBInvocation

Parameters:

transactionContext - the transaction context to use

createResult

public org.apache.geronimo.core.service.InvocationResult createResult(Object object)

Specified by:

createResult in interface EJBInvocation

createExceptionResult

public org.apache.geronimo.core.service.InvocationResult createExceptionResult(Exception exception)

Specified by:

createExceptionResult in interface EJBInvocation

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Specified by:

writeExternal in interface Externalizable

Throws:

IOException

readExternal

public void readExternal(ObjectInput in)
                  throws IOException,
                         ClassNotFoundException

Specified by:

readExternal in interface Externalizable

Throws:

IOException

ClassNotFoundException
