Method Detail

getCommandId
public byte getCommandId()
Description copied from interface:ReplicableCommandUsed by marshallers to convert this command into an id for streaming.- Specified by:
getCommandIdin interfaceReplicableCommand- Returns:
- the method id of this command. This is compatible with pre-2.2.0 MethodCall ids.
-
writeTo
public void writeTo(ObjectOutput output) throws IOException
Description copied from interface:ReplicableCommandWrites this instance to theObjectOutput.- Specified by:
writeToin interfaceReplicableCommand- 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:ReplicableCommandReads this instance from the stream written byReplicableCommand.writeTo(ObjectOutput).- Specified by:
readFromin interfaceReplicableCommand- 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.
-
isReturnValueExpected
public boolean isReturnValueExpected()
Description copied from interface:ReplicableCommandIf true, a return value will be provided when performed remotely. Otherwise, a remoteResponseGeneratormay choose to simply return null to save on marshalling costs.- Specified by:
isReturnValueExpectedin interfaceReplicableCommand- Returns:
- true or false
-
acceptVisitor
public Object acceptVisitor(InvocationContext ctx, Visitor visitor) throws Throwable
Description copied from interface:VisitableCommandAccept a visitor, and return the result of accepting this visitor.- Specified by:
acceptVisitorin interfaceVisitableCommand- Parameters:
ctx- invocation contextvisitor- visitor to accept- Returns:
- arbitrary return value
- Throws:
Throwable- in the event of problems
-
loadType
public VisitableCommand.LoadType loadType()
- Specified by:
loadTypein interfaceVisitableCommand- Returns:
- Nodes on which the command needs to read the previous values of the keys it acts on.
-
getGroupName
public Object getGroupName()
-
isGroupOwner
public boolean isGroupOwner()
-
setGroupOwner
public void setGroupOwner(boolean isGroupOwner)
