DirectedUnpackConnection.RdImplementation of ConnectionInterface which represents a
directed flow of info between a head module to a tail module.
This is an extension of DirectedConnection designed to
unpack a specific named value out of a list outputted by the
head module as input into the tail module's execution rather
than using the direct output of the head module as input into
the tail module.
DirectedUnpackConnection
An object of class R6ClassGenerator of length 25.
new(name, headModule, tailModule, inputArgument)name: unique character string that identifies
this connection.
headModule: obj that implements
ModuleInterface or a character string that
represents the head module of this connection.
tailModule: obj that implements
ModuleInterface or a character string that
represents thetail module of this connection.
inputArgument: name of the inputArgument
the output of the head module is used for in the tail
module's execution. Should be named with what value should
be unpacked out of the head module's return list and used
for the tail module's execution.
filterOutputValue(outputValue)Filters the output of the headModule, outputValue, to what is expected by the tailModule. With this implementation of a directed connection, assumes outputValue is a list and the associated name of inputArgument is used to filter down outputValue.
Returns: filtered outputValue
