evbunpack is a command ensemble that's intended to work with pman to support dynamically setting up analysis of data from event built data sources.
The concept is that you use evbunpack to create
a CEventBuilderEventProcessor at script level.
You can then tell that processor to use an event processing pipeline
to analyze data from each source id found in event builder fragments.
Naturally, this can be cascaded such that a pipeline might contain
another event builder event processor which allows SpecTcl
to process data from hierarchically built events.
Once you've created and stocked you event processor, you can then use pman to create a pipeline whose first element is that event processor.
The evbunpack command is actually a command ensemble. The first command parameter is, therefore, a subcommand that tells evbunpack what to actually do:
evbunpack create evpname frequency diag-basename
Creates a new event processor for unpacking
event built data. evpname
give the processor a name that will be used to
register it with the pipeline manager, thus making
it available to the pman command.
frequency is the frequency of
the timestamping clock in MHz. This is used to construct
the elapsed run time parameter diagnostic parameter of
the event processor.
diag-basename is the base name of
a set of tree parameters. The event processor produces
and maintains a set of diagnostic parameters that can
be used to monitor the correctness of the event builder.
See the programming reference manual's documentation
of CEventBuilderEventProcessor
for more informationa about the set of diagnostic parameters
produced.
Once created without error, the event processor is registered with the pman command allowing it to be placed into event processing pipelines.
evbunpack addprocessor evpname sid pipe-name
Tells the event processor to use an existing event processing
pipeline to analyze fragments from a specific data source.
evpname is the name of an event
processor created by evbunpack create.
sid is the source id of the fragments
pipe-name should handle.
pipe-name is the name of a pipeline
that pman knows about and can be
arbitrarily complex.
evbunpack list ?pattern?
Returns a Tcl list of the event processors this command has created.
