4 Module behavior/reporter
| (require behavior/reporter) | package: behavior |
This module provides a set of functions that construct reporter functions used be the models above. Effectively, each of the behavior models will emit history-events that correspond to changes in the execution state.
To this end the make-?-execution functions will take a reporter optional parameter. In general, if no reporter is specified, the null (make-null-reporter) reporter is used.
struct
(struct history-event (time) #:transparent) time : real?
These events are sent to a reporter function to denote an action taken place
within a behavior execution. These structures cannot be created directly,
it is intended as the parent of behavior-specific history events.
procedure
Creates a reporter that consumes all events and does nothing.
procedure
(make-buffering-reporter selector)
→
(-> list?) (-> history-event? void?) selector : (-> history-event? any/c)
This function creates a reporter that buffers all the events sent to it. It
returns two values; the first if a function that returns the current buffer
as a list, the second is the reporter function itself. The selector
function is called to buffer a subset of the passed event, else the entire event is
buffered.
procedure
(make-channel-reporter) →
channel? (-> history-event? void?)
Returns two values; the first is a newly created channel and the
second is a reporter function that will accept events and write them to
this channel.
procedure
(make-logging-reporter [a-logger]) → (-> history-event? void?)
a-logger : logger? = (current-logger)
Returns a reporter function that will accept events and write them to a
standard racket logger.
procedure
(make-port-reporter port) → (-> history-event? void?)
port : output-port?
Returns a reporter function that will accept events and write them to a
standard racket output-port?.
