iterConnections

lsst.pipe.base.iterConnections(connections: lsst.pipe.base.connections.PipelineTaskConnections, connectionType: str) → Generator[T_co, T_contra, V_co]

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.
