The callback PostTechInitAttributes(CENPyOlpTech_AttribInitOperator) is called just after the kernel initializes the technology attributes.
It can be used to:
- initialize attributes
- get attribute values
- set attribute values
- access OlpController
- output to the log
The callback is defined in the %TechnologyName%.py file that is located in the scripts folder of the plugin.
[Example]
def PostTechInitAttributes(techAttribInitOperator):
# Create attributes
attribCreator = techAttribInitOperator.GetAttribCreator() # get object of CENPyOlpAttribCreator class
attribCreator.AddInteger('MyIntAttribute', 0, -100, 0, USER_ATTRIBUTE | PROCESS_ATTRIBUTE | GLOBAL_ATTRIBUTE, 'MyIntAttribute')
attribCreator.AddDouble('MyDoubleAttribute', 55.5, 0, 100, 0.5, USER_ATTRIBUTE | PROCESS_ATTRIBUTE | GLOBAL_ATTRIBUTE, ATTRIB_STANDARD, 'MyDoubleAttribute')
attribCreator.AddString('MyStringAttribute', 'Hello World', USER_ATTRIBUTE | PROCESS_ATTRIBUTE | GLOBAL_ATTRIBUTE, 'MyStringAttribute')
attribCreator.AddBool('MyBoolAttribute', True, USER_ATTRIBUTE | PROCESS_ATTRIBUTE | GLOBAL_ATTRIBUTE, 'MyBoolAttribute')
myLiterals = ["earth", "revolves", "around"] # list of three literals
myLiterals.insert(0,"The") # insert a new literal at first list position
myLiterals.append("sun") # append a new literal at last list position
attribCreator.AddEnum('MyEnumAttribute', myLiterals, 'earth', USER_ATTRIBUTE | PROCESS_ATTRIBUTE | GLOBAL_ATTRIBUTE, 'MyEnumAttribute')
# Get values from attributes
attribGetter = techAttribInitOperator.GetAttribGetter()
valOfMyIntAttrib = attribGetter.GetInteger('MyIntAttribute')
valOfMyDoubleAttrib = attribGetter.GetDouble('MyDoubleAttribute')
valOfMyStrAttrib = attribGetter.GetString('MyStringAttribute')
valOfMyBoolAttrib = attribGetter.GetBool('MyBoolAttribute')
indexOfMyEnumAttrib = attribGetter.GetEnumIndex('MyEnumAttribute')
# Set values to the attributes
attribSetter = techAttribInitOperator.GetAttribSetter()
attribSetter.SetInteger('MyIntAttribute', 15)
attribSetter.SetDouble('MyDoubleAttribute', 15.8)
attribSetter.SetString('MyStringAttribute', 'This is new string')
attribSetter.SetBool('MyBoolAttribute', False)
attribSetter.SetEnumIndex('MyEnumAttribute', 4)
# Output attribute value to the log
logOperator = techAttribInitOperator.GetLoggerOperator()
logOperator.LogDebug('indexOfMyEnumAttrib = ' + str(indexOfMyEnumAttrib))
# Create system attributes
sysAttribCreator = attribCreator.GetSystemAttribCreator()
min_radius = sysAttribCreator.AddMinRadius(0.01, USER_ATTRIBUTE | PROCESS_ATTRIBUTE | GLOBAL_ATTRIBUTE | OPERATION_ATTRIBUTE)
max_radius = sysAttribCreator.AddMaxRadius(9.9, USER_ATTRIBUTE | PROCESS_ATTRIBUTE | GLOBAL_ATTRIBUTE | OPERATION_ATTRIBUTE)
As a result, new attributes appear on the user interface:
