Interface HostControllerRegistrationHandler.OperationExecutor

Enclosing class:

HostControllerRegistrationHandler

public static interface HostControllerRegistrationHandler.OperationExecutor

Wrapper to the DomainController and the underlying ModelController to execute a OperationStepHandler implementation directly, bypassing normal domain coordination layer. TODO This interface probably should be adapted to provide use-case-specific methods instead of generic "execute whatever I hand you" ones. The "installSlaveExtensions" method needed to be non-generic unless I was willing to hand a ref to the root MRR to RemoteDomainConnnectionService.

Method Summary

Modifier and Type	Method and Description
void	acquireReadlock(Integer operationID) Attempts to acquire a non-exclusive read lock.
org.jboss.dmr.ModelNode	execute(org.jboss.as.controller.client.Operation operation, org.jboss.as.controller.client.OperationMessageHandler handler, ModelController.OperationTransactionControl control, OperationStepHandler step) Execute the operation.
org.jboss.dmr.ModelNode	executeReadOnly(org.jboss.dmr.ModelNode operation, OperationStepHandler handler, ModelController.OperationTransactionControl control) Execute an operation using the current management model.
org.jboss.dmr.ModelNode	executeReadOnly(org.jboss.dmr.ModelNode operation, Resource model, OperationStepHandler handler, ModelController.OperationTransactionControl control) Execute an operation using given resource model.
org.jboss.dmr.ModelNode	installSlaveExtensions(List<org.jboss.dmr.ModelNode> extensions) Execute the operation to install extensions provided by a remote domain controller.
void	releaseReadlock(Integer operationID) Release the non-exclusive read lock obtained from #acquireReadlock.

Method Detail

execute

org.jboss.dmr.ModelNode execute(org.jboss.as.controller.client.Operation operation,
                                org.jboss.as.controller.client.OperationMessageHandler handler,
                                ModelController.OperationTransactionControl control,
                                OperationStepHandler step)

Execute the operation.

Parameters:

operation - operation

handler - the message handler

control - the transaction control

step - the step to be executed

Returns:

the result

installSlaveExtensions

org.jboss.dmr.ModelNode installSlaveExtensions(List<org.jboss.dmr.ModelNode> extensions)

Execute the operation to install extensions provided by a remote domain controller.

Parameters:

extensions@return - the result

executeReadOnly

org.jboss.dmr.ModelNode executeReadOnly(org.jboss.dmr.ModelNode operation,
                                        OperationStepHandler handler,
                                        ModelController.OperationTransactionControl control)

Execute an operation using the current management model.

Parameters:

operation - the operation

handler - the operation handler to use

Returns:

the operation result

executeReadOnly

org.jboss.dmr.ModelNode executeReadOnly(org.jboss.dmr.ModelNode operation,
                                        Resource model,
                                        OperationStepHandler handler,
                                        ModelController.OperationTransactionControl control)

Execute an operation using given resource model.

Parameters:

operation - the operation

model - the resource model

handler - the operation handler to use

Returns:

the operation result

acquireReadlock

void acquireReadlock(Integer operationID)
              throws IllegalArgumentException,
                     InterruptedException

Attempts to acquire a non-exclusive read lock. After any operations requiring this lock have completed, #releaseReadlock must be called to release the lock.

Parameters:

operationID - - the operationID for this registration. Cannot be null.

Throws:

IllegalArgumentException - - if operationID is null.

InterruptedException - - if the lock is not acquired.

releaseReadlock

void releaseReadlock(Integer operationID)
              throws IllegalArgumentException

Release the non-exclusive read lock obtained from #acquireReadlock. This method must be called after any locked operations have completed or aborted to release the shared lock.

Parameters:

operationID - - the operationID for this registration. Cannot be null.

Throws:

IllegalArgumentException - - if if the operationId is null.

IllegalStateException - - if the shared lock was not held.
