Object |
acceptVisitor(InvocationContext ctx,
Visitor visitor)
Accept a visitor, and return the result of accepting this visitor.
|
boolean |
canBlock()
If true, the command is processed asynchronously in a thread provided by an Infinispan thread pool.

getKeys() |
Map<Object,InternalCacheEntry> |
getRemotelyFetched() |
boolean |
ignoreCommandOnStatus(ComponentStatus status)
Similar to

boolean |
isReturnEntries() |
boolean |
isReturnValueExpected()
If true, a return value will be provided when performed remotely.
|
Object |
perform(InvocationContext ctx)
Performs the primary function of the command.
|
void |
readFrom(ObjectInput input)
Reads this instance from the stream written by
ReplicableCommand.writeTo(ObjectOutput) . |

boolean |
shouldInvoke(InvocationContext ctx)
Used by the InboundInvocationHandler to determine whether the command should be invoked or not.
|
