Method Detail

getInvocationContext

@Deprecated
InvocationContext getInvocationContext(boolean quiet)

Deprecated. see implementation for notes

Returns the InvocationContext that is currently associated with the calling thread. Important: implementations of this method are most likely expensive, involving thread locals. It is recommended to cache the result of this method rather than repeating the call.

Parameters:

quiet -

Throws:

IllegalStateException - if there is no context associated with the current thread.

createInvocationContext

InvocationContext createInvocationContext(boolean isWrite,
                                        int keyCount)

If we are in a tx scope this will return an TxInvocationContext. Otherwise it will return an NonTxInvocationContext. Either way, both context will be marked as local, i.e. InvocationContext.isOriginLocal() will be true.

createInvocationContext

InvocationContext createInvocationContext(Transaction tx)

Creates an invocation context

Parameters:

tx -

Returns:

createNonTxInvocationContext

NonTxInvocationContext createNonTxInvocationContext()

Will create an NonTxInvocationContext with the AbstractInvocationContext.isOriginLocal() returning true.

createSingleKeyNonTxInvocationContext

InvocationContext createSingleKeyNonTxInvocationContext()

Will create an NonTxInvocationContext with the AbstractInvocationContext.isOriginLocal() returning true.

createTxInvocationContext

LocalTxInvocationContext createTxInvocationContext()

Returns a LocalTxInvocationContext.

createRemoteTxInvocationContext

RemoteTxInvocationContext createRemoteTxInvocationContext(RemoteTransaction tx,
                                                        Address origin)

Returns an RemoteTxInvocationContext.

Parameters:

tx - remote transaction

origin - the origin of the command, or null if local

createRemoteInvocationContext

InvocationContext createRemoteInvocationContext(Address origin)

Returns an NonTxInvocationContext whose AbstractInvocationContext.isOriginLocal() flag will be true.

Parameters:

origin - the origin of the command, or null if local

createRemoteInvocationContextForCommand

InvocationContext createRemoteInvocationContextForCommand(VisitableCommand cacheCommand,
                                                        Address origin)

As createRemoteInvocationContext(org.infinispan.remoting.transport.Address), but returning the flags to the context from the Command if any Flag was set.

Parameters:

cacheCommand -

origin - the origin of the command, or null if local

clearThreadLocal

void clearThreadLocal()

Must be called as each thread exists the interceptor chain.
