Package com.ibm.jbatch.spi.services

The interfaces in this package reflect the fine-grained modularity of the batch runtime. Though there is probably enough tight-coupling that a third-party implementation of one of these "services" might not work out of the box, there is at least enough of a well-defined interface here that we can point to this package as the starting point for extending/modifying the batch runtime implementation with different behaviors with perhaps different qualities of service.
