Entuple data
Receives data on its "inbox" inbox; wraps that data inside a tuple,
and outputs that tuple from its "outbox" outbox.
Example Usage
Taking console input and sandwiching it in a tuple between the
strings ("You" and "said") and ("just" and now"):
Pipeline( ConsoleReader(),
Entuple(prefix=["You","said"], postfix=["just","now"]),
ConsoleEchoer(),
).run()
- At runtime::
-
>>> Hello there!
('You', 'said', 'Hello there!', 'just', 'now')
How does it work?
At initialisation specify a list of items to be placed at the front
(prefix) and back (postfix) of the tuples that are output.
When an item of data is received at the "inbox" inbox; it is placed
inside a tuple, after the prefixes and before the postfixes. It is then
immediately sent out of the "outbox" outbox.
For example: if the prefix is [1,2,3] and the postfix is ['a','b']
and the item of data that arrives is 'flurble' then
(1,2,3,'flurble','a','b') will be sent to the "outbox" outbox.
If Entuple receives a shutdownMicroprocess message on its "control"
inbox, it will pass it on out of the "signal" outbox. The component will
then terminate.
