All Implemented Interfaces:: OperationFactory

Direct Known Subclasses:: AsciiOperationFactory, BinaryOperationFactory

public abstract class BaseOperationFactory extends 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.

  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
- cloneGet
  
  protected abstract Collection<? extends Operation> cloneGet(KeyedOperation op)
