Object |
acceptVisitor(InvocationContext ctx,
Visitor visitor)
Accept a visitor, and return the result of accepting this visitor.
|
boolean |
equals(Object o) |

getCommandId()
Used by marshallers to convert this command into an id for streaming.
|
Object[] |
getParameters()
Used by marshallers to stream this command across a network
|
int |
hashCode() |
boolean |
ignoreCommandOnStatus(ComponentStatus status)
Similar to
VisitableCommand.shouldInvoke(InvocationContext) but evaluated by InvocationContextInterceptor . |
void |
init(Cache<Object,Object> cache) |
boolean |
isReturnValueExpected()
If true, a return value will be provided when performed remotely.
|
Object |
perform(InvocationContext context)
Performs invocation of Callable and returns result
|
void |
setParameters(int commandId,
Object[] args)
Used by the
CommandsFactory to create a command from raw data read off a stream. |
boolean |
shouldInvoke(InvocationContext ctx)
Used by the InboundInvocationHandler to determine whether the command should be invoked or not.
