Method Detail

resourceMustExist

protected boolean resourceMustExist(OperationContext context,
                                    org.jboss.dmr.ModelNode operation)

Description copied from class: AbstractRuntimeOnlyHandler

By default the handler will check whether the resource exist before calling @{link #executeRuntimeStep(OperationContext, ModelNode)}. This method can be overridden in the special case where a runtime operation must be executed without a corresponding resource.

Overrides:

resourceMustExist in class AbstractRuntimeOnlyHandler

Parameters:

context - the operation context

operation - the operation being executed

Returns:

true if the resource must exist for this runtime handler to be executed.

executeRuntimeStep

public void executeRuntimeStep(OperationContext context,
                               org.jboss.dmr.ModelNode operation)
                        throws OperationFailedException

Description copied from class: AbstractRuntimeOnlyHandler

Execute this step in OperationContext.Stage.RUNTIME. If the operation fails, context.getFailureDescroption() must be called, or OperationFailedException must be thrown, before calling one of the context.completeStep variants. If the operation succeeded, context.getResult() should be called and the result populated with the outcome, after which one of the context.completeStep variants must be called.

Specified by:

executeRuntimeStep in class AbstractRuntimeOnlyHandler

Parameters:

context - the operation context

operation - the operation being executed

Throws:

OperationFailedException - if the operation failed before calling context.completeStep()
