getCommandId
public byte getCommandId()Description copied from interface:ReplicableCommandUsed 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.
-
writeTo
Description copied from interface:ReplicableCommandWrites this instance to theObjectOutput.- Parameters:
output- the stream.- Throws:
IOException- if an error occurred during the I/O.
-
readFrom
Description copied from interface:ReplicableCommandReads this instance from the stream written byReplicableCommand.writeTo(ObjectOutput).- 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.
-
acceptVisitor
Description copied from interface:VisitableCommandAccept a visitor, and return the result of accepting this visitor.- Parameters:
ctx- invocation contextvisitor- visitor to accept- Returns:
- arbitrary return value
- Throws:
Throwable- in the event of problems
-
loadType
- Returns:
- Nodes on which the command needs to read the previous values of the keys it acts on.
