Method Detail

requiresRuntime

protected boolean requiresRuntime(OperationContext context)

Description copied from class: AbstractRuntimeOnlyHandler

Gets whether the OperationContext.Stage.RUNTIME step should be added to call AbstractRuntimeOnlyHandler.executeRuntimeStep(OperationContext, ModelNode). This default implementation will return true for a normal server running in normal (non admin-only) mode. If running on a host controller, it will return true if it is the active copy of the host controller subsystem. Subclasses that perform no runtime update could override and return false. This method is invoked during OperationContext.Stage.MODEL.

Overrides:

requiresRuntime in class AbstractRuntimeOnlyHandler

Parameters:

context - operation context

Returns:

true if a step to invokeexecuteRuntimeStep should be added; false otherwise.
