CENPyOlpWM_AttribChangedOperator

The object of the CENPyOlpWM_AttribChangedOperator class is passed to the PostWmOnAttribChanged callback as a parameter.

It can be used to obtain the required operators within the scope of the PostWmOnAttribChanged callback in the %WORK_METHOD%.py script file, located in the folder of the plugin.

[Example]

def PostWmOnAttribChanged(wmAttribChangedOperator):

   pass

Methods

This operator gives the possibility to find attribute and get their values.

[Example]

   attribGetter = wmAttribChangedOperator.GetAttribGetter()

This operator gives the possibility to change attribute values.

[Example]

   attribSetter = wmAttribChangedOperator.GetAttribSetter()

This operator gives the possibility to log issues resulting by user input.

[Example]

   logOperator = wmAttribChangedOperator.GetLoggerOperator()

This operator gives the possibility to open a csv file and read the data.

[Example]

   csvOperator = wmAttribChangedOperator.GetCsvParserOperator()

This method returns the world matrix of the attribute reference object.

If the attribute does not have a reference object, the returned matrix will be unit.

[Example]

   worldMatrix = wmAttribChangedOperator.GetWorldReference()

This method returns the assigned controller.

[Example]

   controller = wmAttribChangedOperator.GetController()

 Method is deprecated, consider using GetChangedAttributeName()

 This method returns the changed attribute which rises the OnAttribChanged callback.

[Example]

   changedAttrib = wmAttribChangedOperator.GetChangedAttribute()

 This method returns the name of changed attribute which rises OnAttribChanged callback.

[Example]

def PostOnAttribChanged(Operator):

   logging = Operator.GetLoggerOperator()

   logging.LogInfo(FILE_NAME +" GetChangedAttributeName:"+ Operator.GetChangedAttributeName())

This method returns the object of the container on which the attribute change happened.

[Example]

See example for GetOperatorForComponent below.

This method returns object of the container on which the attribute change happened.

[Example]

def PostWmOnAttribChanged(Operator):

# Code shows how to propagate attribute values from Program level to Operation level

# get attribute getter and setter

    attribGetter = Operator.GetAttribGetter()

    attribSetter = Operator.GetAttribSetter()  

    # get the changed attribute name and check if we have to do something

    changedAttribute = Operator.GetChangedAttribute()

    changedAttributeName = changedAttribute.GetName()

    if (changedAttribute.GetName() == "TestMaster"):        

        intAttrib = attribGetter.GetAttributeIntegerByName("TestMaster")

        if intAttrib != None:

            program = Operator.GetChangedComponent()

            if program.GetType() == OLPPROGRAMCOMPONENTTYPE_PROGRAM:

                groupComponents = program.GetChildComponents()

                for groupComponent in groupComponents:

                    if (groupComponent.GetType() == OLPPROGRAMCOMPONENTTYPE_OPERATIONGROUP):

                        operationComponents = groupComponent.GetChildComponents()

                        for operationComponent in operationComponents:

                            if (operationComponent.GetType() == OLPPROGRAMCOMPONENTTYPE_OPERATION):

                                componentOperator = Operator.GetOperatorForComponent(operationComponent)

                                componentAttribSetter = componentOperator.GetAttribSetter()

                                componentAttribSetter.SetInteger("TestSubscriber", intAttrib.GetValue())
