ignoreCommandOnStatus(ComponentStatus status)
Similar to
VisitableCommand.shouldInvoke(InvocationContext) but evaluated by InvocationContextInterceptor . |
boolean |
isConditional()
Certain commands only work based on a certain condition or state of the cache.
|
boolean |
isSuccessful()
Some commands may want to provide information on whether the command was successful or not.
|
Object |
perform(InvocationContext ctx)
Performs an application of delta on a specified entry
|
void |
setParameters(int commandId,

ConcurrentMap.putIfAbsent(Object, Object)
only does anything if a condition is met, i.e., the entry in
question is not already present. This method tests whether the command in question is conditional or not.Copyright © 2012 JBoss by Red Hat. All Rights Reserved.
