Method Detail

acceptVisitor

public Object acceptVisitor(InvocationContext ctx,
                            Visitor visitor)
                     throws Throwable

Description copied from interface: VisitableCommand

Accept a visitor, and return the result of accepting this visitor.

Parameters:

ctx - invocation context

visitor - visitor to accept

Returns:

arbitrary return value

Throws:

Throwable - in the event of problems

invalidRemoteTxReturnValue

protected Object invalidRemoteTxReturnValue(TransactionTable txTable)

Description copied from class: AbstractTransactionBoundaryCommand

This is what is returned to remote callers when an invalid RemoteTransaction is encountered. Can happen if a remote node propagates a transactional call to the current node, and the current node has no idea of the transaction in question. Can happen during rehashing, when ownerships are reassigned during a transactions. Returning a null usually means the transactional command succeeded.

Overrides:

invalidRemoteTxReturnValue in class AbstractTransactionBoundaryCommand

Returns:

return value to respond to a remote caller with if the transaction context is invalid.

getCommandId

public byte getCommandId()

Description copied from interface: ReplicableCommand

Used by marshallers to convert this command into an id for streaming.

Returns:

the method id of this command. This is compatible with pre-2.2.0 MethodCall ids.

toString

public String toString()

Overrides:

toString in class AbstractTransactionBoundaryCommand

writeTo

public void writeTo(ObjectOutput output)
             throws IOException

Description copied from interface: ReplicableCommand

Writes this instance to the ObjectOutput.

Specified by:

writeTo in interface ReplicableCommand

Overrides:

writeTo in class AbstractTransactionBoundaryCommand

Parameters:

output - the stream.

Throws:

IOException - if an error occurred during the I/O.

readFrom

public void readFrom(ObjectInput input)
              throws IOException,
                     ClassNotFoundException

Description copied from interface: ReplicableCommand

Reads this instance from the stream written by ReplicableCommand.writeTo(ObjectOutput).

Specified by:

readFrom in interface ReplicableCommand

Overrides:

readFrom in class AbstractTransactionBoundaryCommand

Parameters:

input - the stream to read.

Throws:

IOException - if an error occurred during the I/O.

ClassNotFoundException - if it tries to load an undefined class.

addIracMetadata

public void addIracMetadata(int segment,
                            IracMetadata metadata)

getIracMetadata

public IracMetadata getIracMetadata(int segment)
