      • 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.

      • invoke

        public java.lang.Object invoke()
                        throws java.lang.Throwable
        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.

        Throws:
        java.lang.Throwable

      • toString

        public java.lang.String toString()
        Overrides:
        toString in class org.infinispan.commands.remote.BaseRpcCommand

      • init

        public void init​(ComponentRegistry componentRegistry,
                 boolean isRemote)
        Specified by:
        init in interface org.infinispan.commands.InitializableCommand

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

      • readFrom

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