CENPyOlpTech_AttribChangedOperator

The object of the CENPyOlpTech_AttribChangedOperator class is passed to the PostTechOnAttribChanged callback as a parameter.

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

[Example]

def PostTechOnAttribChanged(techAttribChangedOperator):

pass

Methods

•	GetAttribGetter()

return

Object of CENPyOlpAttribGetter class

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

[Example]

attribGetter = techAttribChangedOperator.GetAttribGetter()

•	GetAttribSetter()

return

Object of CENPyOlpAttribSetter class

This operator gives the possibility to change attribute values.

[Example]

attribSetter = techAttribChangedOperator.GetAttribSetter()

•	GetLoggerOperator()

return

Object of CENPyOlpLogOperator class

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

[Example]

logOperator = techAttribChangedOperator.GetLoggerOperator()

•	GetController()

return

Object of CENPyOlpController class

This method returns the assigned controller.

[Example]

controller = techAttribChangedOperator.GetController()

Method is deprecated, consider using GetChangedAttributeName()

•	GetChangedAttribute()

return

Object of CENPyOlpAttribute class

This method returns the changed attribute which rises OnAttribChanged callback.

[Example]

changedAttrib = techAttribChangedOperator.GetChangedAttribute()

•	GetChangedAttributeName()

return

name of the changed attribute

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())

•	GetChangedComponent()

return

Object of CENPyOlpProgramComponent class that contain changed attribute, can be program, operation group or operation.

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

[Example]

See example for GetOperatorForComponent below.

•	GetOperatorForComponent(prgComponent: CENPyOlpProgramComponent) : CENPyOlpTech_AttribChangedOperator

o	prgComponent

program component to get an operator for it

return

Object of CENPyOlpTech_AttribChangedOperator class that represents attribute change operator for program, operation group or operation.

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

[Example]

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

# get attribute getter and setter

def PostTechOnAttribChanged(Operator):

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())
