    Direct Known Subclasses:
    AsciiOperationFactory, BinaryOperationFactory

    public abstract class BaseOperationFactory
    extends java.lang.Object
    implements OperationFactory
    Base class for operation factories.

    There is little common code between OperationFactory implementations, but some exists, and is complicated and likely to cause problems.

      • first

        private java.lang.String first​(java.util.Collection<java.lang.String> keys)
      • clone

        public java.util.Collection<Operation> clone​(KeyedOperation op)
        Description copied from interface: OperationFactory
        Clone an operation.

        This is used for requeueing operations after a server is found to be down.

        Note that it returns more than one operation because a multi-get could potentially need to be played against a large number of underlying servers. In this case, there's a separate operation for each, and callback façade to reassemble them. It is left up to the operation pipeline to perform whatever optimization is required to turn these back into multi-gets.

        Specified by:
        clone in interface OperationFactory
        Parameters:
        op - the operation to clone
        Returns:
        a new operation for each key in the original operation
