attributes - all persistent attributes of the

runtimeAttributes - attributes whose updated value can immediately be applied to the runtime

Method Detail

applyUpdateToRuntime

protected boolean applyUpdateToRuntime(OperationContext context,
                                       org.jboss.dmr.ModelNode operation,
                                       String attributeName,

                                throws OperationFailedException

Description copied from class: AbstractWriteAttributeHandler

Hook to allow subclasses to make runtime changes to effect the attribute value change.

Specified by:

applyUpdateToRuntime in class AbstractWriteAttributeHandler<Boolean>

Parameters:

context - the context of the operation

operation - the operation

attributeName - the name of the attribute being modified

newValue - the new value for the attribute, after ModelNode.resolve() has been called on it

currentValue - the existing value for the attribute

handbackHolder - holder for an arbitrary object to pass to AbstractWriteAttributeHandler.revertUpdateToRuntime(OperationContext, ModelNode, String, ModelNode, ModelNode, Object) if the operation needs to be rolled back

Returns:

true if the server requires reload to effect the attribute value change; false if not

Throws:

OperationFailedException

revertUpdateToRuntime

protected void revertUpdateToRuntime(OperationContext context,
                                     org.jboss.dmr.ModelNode operation,
                                     String attributeName,
                                     org.jboss.dmr.ModelNode valueToRestore,
                                     org.jboss.dmr.ModelNode valueToRevert,
                                     Boolean handback)
                              throws OperationFailedException

Description copied from class: AbstractWriteAttributeHandler

Hook to allow subclasses to revert runtime changes made in AbstractWriteAttributeHandler.applyUpdateToRuntime(OperationContext, ModelNode, String, ModelNode, ModelNode, HandbackHolder).

Specified by:

revertUpdateToRuntime in class AbstractWriteAttributeHandler<Boolean>

Parameters:

context - the context of the operation

operation - the operation

attributeName - the name of the attribute being modified

valueToRestore - the previous value for the attribute, before this operation was executed

valueToRevert - the new value for the attribute that should be reverted

handback - an object, if any, passed in to the handbackHolder by the applyUpdateToRuntime implementation

Throws:

OperationFailedException
