ProcessorNode build()ProcessorNodeFactory
ProcessorNodeFactory is a concrete NodeFactory that can build a processor node for a ProcessorSupplier and optional state stores.
|
Note
|
ProcessorNodeFactory is a private class.
|
ProcessorNodeFactory is created exclusively when InternalTopologyBuilder is requested to register a global state store or addProcessor.
ProcessorNodeFactory manages names of the state stores that a Processor can be associated with (as part of a ProcessorNode).
ProcessorNodeFactory can have state stores registered (by the name) (which happens when InternalTopologyBuilder is requested to register a global state store or connectProcessorAndStateStore).
