Register a Scorpion Plugin in Scorpion. A Scorpion Plugin may be any python class

Syntax:

RegisterPlugin(instance,unregisterMethod)

UnregisterPlugin(instance) - optional, will be called by Scorpion in "Central Restart"

• instance - the python instance

• optional unregisterMethod before unregister, may be name of method or the instancemethod itself

  • The UnregisterPlugin method is call after the "Central Stop" script

The UnregisterPlugin method unregisteres all callbacks registered with RegisterCallback.

Plugin requirements:

The plugin implemtation uses the Python weak reference mechanisms which requires a class method '__call__(self)'. For derived DotNet controls this method already exists. If the "__call__(self)" don't exists an empty method may be implemented.

Example 1: Class foo - calling standard destructor

def CreatePlugin():

class Plugin:
  def __init__(self):
    RegisterCallback('Actions.AfterInspect',self.AfterInpect)

  def CentralStop(self):
    self.save()
    self.dispose()
    print 'Plugin.Central Stop'

  def AfterInspect(self):
    print self,'update'

  return Plugin()

Central Start

  RegisterPlugin(CreatePlugin(),'CentralStop')

  or

  plugin=CreatePlugin()
  RegisterPlugin(plugin,plugin.CentralStop)

Note : "Central Stop" is empty, all plugins and its registered callbacks are automatically removed after 'Central Stop' so no cleanup code is nessesary in "Central Stop" script
