public interface ProcessingService

Interface of SMILA ProcessingServices (aka "Big Pipelets"). In contrast to "SimplePipelets" instances of ProcessingServices are not instantiated and configured by the Workflow engine, but are started as OSGi services (preferably by Declarative Services) independently from the workflow engine and can read their configuration from wherever they want. Their service registration must have a property named "smila.processing.service.name" that specifies the name with which the service is references by the workflow engine.
