The callback PostTechUpdate(CENPyOlpTech_UpdateOperator) is called from the kernel when a technology update should be processed.
When loading the project file, the current version of the technology python script, defined in the same script by the GetPythonTechnologyVersion() parameter, is compared to the technology python script, that was saved during the last E2 session. The Update callback is called only when the current version of the technology python script is higher than the previous script version. The minimum and default GetPythonTechnologyVersion() script version parameter is 0.
It can be used to:
- get attribute values
- set attribute values
- create new attributes
- output to the log
- access OlpController
- access program components: OlpProgram, OlpOperationGroup, OlpOperation, OlpEvent, OlpEventRule
- access OlpTech_RuleUpdateOperator, OlpWM_RuleUpdateOperator
The callback may return a boolean value. There is no need to return False, because the default value is anyway False:
- True: if it is necessary to perform a full program recompute after the callback ends
- False: otherwise
The callback is defined in the %TechnologyName%.py file that is located in the scripts folder of the plugin.
