    • Constructor Detail

      • ForwardCommitCommand

        public ForwardCommitCommand​(ByteString cacheName)
      • ForwardCommitCommand

        public ForwardCommitCommand​(ByteString cacheName,
                                    XidImpl xid,

    • Method Detail

      • getCommandId

        public byte getCommandId()
        Description copied from interface: org.infinispan.commands.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.
      • isReturnValueExpected

        public boolean isReturnValueExpected()
        Description copied from interface: org.infinispan.commands.ReplicableCommand
        If true, a return value will be provided when performed remotely. Otherwise, a remote ResponseGenerator may choose to simply return null to save on marshalling costs.
        Returns:
        true or false
      • canBlock

        public boolean canBlock()
        Description copied from interface: org.infinispan.commands.ReplicableCommand
        If true, the command is processed asynchronously in a thread provided by an Infinispan thread pool. Otherwise, the command is processed directly in the JGroups thread.

        This feature allows to avoid keep a JGroups thread busy that can originate discard of messages and retransmissions. So, the commands that can block (waiting for some state, acquiring locks, etc.) should return true.

        Specified by:
        canBlock in interface org.infinispan.commands.ReplicableCommand
        Overrides:
        canBlock in class org.infinispan.commands.remote.BaseRpcCommand
        Returns:
        true if the command can block/wait, false otherwise
      • writeTo

        public void writeTo​(ObjectOutput output)
                     throws IOException
        Description copied from interface: org.infinispan.commands.ReplicableCommand
        Writes this instance to the ObjectOutput.
        Parameters:
        output - the stream.
        Throws:
        IOException - if an error occurred during the I/O.
      • readFrom

        public void readFrom​(ObjectInput input)
                      throws IOException
        Description copied from interface: org.infinispan.commands.ReplicableCommand
        Reads this instance from the stream written by ReplicableCommand.writeTo(ObjectOutput).
        Parameters:
        input - the stream to read.
        Throws:
        IOException - if an error occurred during the I/O.

        Description copied from interface: org.infinispan.commands.ReplicableCommand
        Invoke the command synchronously.

        This method is optional. Unless your command never blocks, please implement ReplicableCommand.invokeAsync() instead.
