April 2024 - This site, and Kamaelia are being updated. There is significant work needed, and PRs are welcome.
For examples and more explanations, see the module level docs.
IntelligentFileReader(filename, chunksize, maxqueue) -> file
reading component
Creates a file reader component. Reads a chunk of chunksize bytes,
using the Selector to avoid having to block, pausing when the length of
its send-queue exceeds maxqueue chunks.
Inboxes
- control : for shutdown signalling
- inbox : wake me up by sending anything here
- _selectorready : ready to read
Outboxes
- debug : information designed to aid debugging
- outbox : data output
- signal : outputs 'producerFinished' after all data
has been read
- _selectorask : ask the Selector to notify readiness
to read on a file
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.
