Parameters

connectionsPipelineTaskConnections

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

connectionTypestr

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

Yields

connection: BaseConnection
