This package extends the schema from the coredal package to describe readout applications.
The ReadoutMap included here is currently a direct translation
from the jsonnet schema in the daqconf package with the addition of
a grouping class ReadoutGroup.
The DROStreamConf class inherits from ResourceBase allowing individual streams to be disabled. DROStreamConfs are grouped into ReadoutGroups which inherit from ResourceSetAND so if all streams in a group are disabled the group itselg is disabled.
The EthStreamParameters and the FlxStreamParameters classes both contain host addresses. It is not clear how these relate to the VirtualHost/PhysicalHost classes from the core schema.
SmartDaqApplication is an abstract class that has no direct
relationships with DaqModules. The DaqModules themselves must
be generated on the fly by an implementation of the
generate_modules() method. The SmartDaqApplication has
relationships to QueueConnectionRules and
NetworkConnectionRules to alow the generate_modules() method to
know how to connect the modules internally and to network endpoints.
NB: The declaration of the generate_modules() method must be
repeated in each subclass and an implementation provided. The
declaration in SmartDaqApplication is not pur virtual but its
implemetation just throws a 'not implemented' exception.
The ReadoutApplication inherits from both SmartDaqApplication
and ResourceSetAND. This means it has a contains relationship that
can contain any class inheriting from RsourceBase but should only
contain ReadoutGroups. The generate_modules() method will
generate a DataReader and set of DataLinkHandlers for each
ReadoutGroup plus a single TPHandler. The modules are created
accoriding to the configuration given by the data_reader, link_handler
and tp_handler relationships respectively. Connections between pairs
of modules are configured according to the queue_rules relationship
inherited from SmartDaqApplication.
The NICReader, which is generated on the fly by the
ReadoutApplication's generate_modules(), has a relationship to a
NICReceiverConf which will be the same for all NICReceivers of
the ReadoutApplication and maybe for all the
ReadoutApplications in the Session. Its only distinguishing
configuration item is the relationship it has to a DROStreamConf.
The Datflow applications, which are also SmartDaqApplication which generate DaqModules on the fly, are also included here.
