PromptedFileReader(filename[,readmode]) -> file reading
component
Creates a file reader component. Reads N bytes/lines from the file
when N is sent to its inbox.
Keyword arguments:
- readmode -- "bytes" or "lines"
Inboxes
- control : for shutdown signalling
- inbox : requests to 'n' read bytes/lines
Outboxes
- outbox : data output
- signal : outputs 'producerFinished' after all data
has been read
Methods defined here
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.
