Integration Application

Quick Start

Create a GUI for your steps in 3 simple steps:

• Create custom classes inheriting ProcessStep
• Use PreCondition, ExecuteStep and PostCondition
• Prepare main

Detailed Steps

1. Create custom classes inheriting ProcessStep

For example: (MySteps.py)

Class StepOne(ProcessStep):
	def __init(self, stepname, filename):
		self.stepname = stepname # stepname is mandatory and may not be changed. Additional parameters could be added.
		self.filename = filename

2. Use PreCondition, ExecuteStep and PostCondition

   def PreCondition(self):
   	print "This function is automatically executed to check the necessary requirements to execute the step
   	return 0 # On Success, return 0
   	#return 1 # On Failure, return non-zero
   
   def ExecuteStep(self):
   	print "This function is where the actual work is done."
   	return 0 # On Success, return 0
   	#return 1 # On Failure, return non-zero
   	
   def PostCondition(self):
   	print "Check whether the ExecuteStep worked as expected."
   	return 0 # On Success, return 0
   	#return 1 # On Failure, return non-zero
   

3. Prepare main

For example: (main.py)

from IntegrationApp import IntegrationApp
from MySteps import StepOne

if __name__ == "__main__":
	process_steps = []
	
	# Instansiating object from Steps and add to process_steps
	parsexls = StepOne("Parse", "suiv.xls")
	process_steps.append(parsexls)
	
	parsecsv = StepOne("Fetch", "install.csv")
	process_steps.append(parsecsv)

	# Start Application and call MainLoop
	app = IntegrationApp(process_steps)
	app.MainLoop()
