cwlWorkflow function

Description

The constructor function for 'cwlWorkflow' object, which connects multiple command line steps into a workflow.

steps: Function to extract and assign workflow step slots.

  intent = list(),
  hints = list(),
  arguments = list(),
  extensions = list(),
  inputs = InputParamList(),
  outputs = OutputParamList(),
  steps = cwlStepList()
)
