iterConnections

lsst.pipe.base.iterConnections(connections: PipelineTaskConnections, connectionType: Union[str, Iterable[str]]) → Generator[BaseConnection, None, None]

Creates an iterator over the selected connections type which yields all the defined connections of that type.

Parameters:

connections: `PipelineTaskConnections`

An instance of a PipelineTaskConnections object that will be iterated over.

connectionType: `str`

The type of connections to iterate over, valid values are inputs, outputs, prerequisiteInputs, initInputs, initOutputs.

Yields:

connection: BaseConnection

A connection defined on the input connections object of the type supplied. The yielded value Will be an derived type of BaseConnection.
