checkResponses

protected void checkResponses(List rsps)
                       throws Throwable

Checks whether any of the responses are exceptions. If yes, re-throws them (as exceptions or runtime exceptions).

Throws:

Throwable

                      throws Throwable

Throws:

Throwable

putCallOnAsyncReplicationQueue

protected void putCallOnAsyncReplicationQueue(MethodCall call)

containsModifications

protected boolean containsModifications(InvocationContext ctx)

skipReplicationOfTransactionMethod

protected boolean skipReplicationOfTransactionMethod(InvocationContext ctx)

It does not make sense replicating a transaction method(commit, rollback, prepare) if one of the following:

    - call was not initiated here, but on other member of the cluster
    - there is no transaction. Why calling a commit if no transaction going on?
    - the current transaction did not modufy any data, so other members are not aware of it
 

isTransactionalAndLocal

protected boolean isTransactionalAndLocal(InvocationContext ctx)

The call runs in a transaction and it was initiated on this node of the cluster.

isSynchronous

protected boolean isSynchronous(Option option)
