Chooses items out of a set, as directed by commands sent to its inbox
Emits the first item at initialisation, then whenever a command is received it emits another item (unless you're asking it to step beyond the start or end of the set)
Warning! You should be using the inbox/outbox interface, not these methods (except construction). This documentation is designed as a roadmap as to their functionalilty for maintainers and new component developers. |
