OutputVariableTransitionRule
[source] This class is a must-override base class for defining transition rules for output variable objects These objects are treated somewhat specially by the tool because a small change can affect so many objects, and it would be unwise to expect each version to include so much repeated code.
The structure of the output objects here is based on 8.5/8.6. In the future, if the objects didn’t change much, it would make most sense to just keep using this class and making small tweaks as needed. If more major changes occur, it would be best to create a new base class to move forward.

complex_output_operation
(full_object, dependent_objects)[source] This method should be overridden in derived classes and should perform the complex operations to transition the argument object passed in. The function should return a list because some complex operations may split the initial object into multiple objects. The object passed in will have any simple name swaps already performed.
Parameters: - full_object – The original object to be replaced.
- dependent_objects – A dictionary of dependent objects
Returns: A list of new IDFObject instances, typically just one though
Raises: UnimplementedMethodException – Raised if this method is called on the base class itself
-
get_complex_operation_types
()[source] This method should be overridden in the derived classes and return a list of object names that require more complex transition operations than a simple variable name swap
Returns: A list of strings, each representing an object name that requires complex transition operations Raises: UnimplementedMethodException – Raised if this method is called on the base class itself
-
get_dependent_object_names
()[source] This method can be overridden in derived classes if any of the output variable name changes depend on other objects in the idf. Simply return a list of object names
Returns: A list of object names that output variable name changes are dependent upon
-
get_output_objects
()[source] This method should be overridden in derived classes and return a list of all output-related object types in this version of EnergyPlus. A base version is available in the base class that can be used as a starter and if an object name changes, the derived class can change that name as needed in the return array.
Returns: A list of strings, each representing an output object type name Raises: UnimplementedMethodException – Raised if this method is called on the base class itself
-
get_simple_swaps
()[source] This method should be overridden in derived classes and return a dictionary where each key is the name of an output variable, and the value of each key is the new variable name. This map is used when doing the simple variable name swaps.
Returns: A dictionary of <old_variable_name, new_variable_name> Raises: UnimplementedMethodException – Raised if this method is called on the base class itself
-
get_standard_indexes_from_object
(object_name)[source] This method should be overridden in derived classes and return a list of the zero-based field indexes that include a variable name in the given object type. A base version is available in the base class that can be used as a starter and if the structure of any object types changes, the derived class can change that one as needed in the return list
Parameters: object_name – The name of the object being inspected Returns: A list of zero-based indexes, each representing a field containing an output variable name Raises: UnimplementedMethodException – Raised if this method is called on the base class itself
-
original_full_variable_type_list
()[source]
-
original_standard_indexes_from_object
(object_name)[source] This method returns the list of indexes where variable names are found. These are zero based indexes. This method returns a base version that can be used by a derived class directly, modified, or used as a template for future derived classes.
Parameters: object_name – The upper case name of the object currently being transitioned. Returns: A list of zero-based indexes
-
simple_name_swap
(variable_name)[source] This method is a simple method that queries the must-override get_simple_swaps method in the derived class and either returns a new variable name to swap in place of the original name, or returns None as a signal that this original variable name does not need replacement
Parameters: variable_name – The original variable name to potentially be replaced Returns: A new variable name, if a swap is to be performed, or None if not
-
transition
(core_object, dependent_objects)[source] This method can be implemented by derived classes if necessary, but should capture the entire transition functionality just using the other required <must-override> methods in this class. This function first scans all the variable names in the current locations, and renames as needed. Then this function checks if this object type needs a complex transition, and if so, calls the appropriate derived method. This method then returns a full IDFObject instance.
Parameters: - core_object – The original object to be replaced
- dependent_objects – A dictionary of dependent objects
Returns: A list of new IDFObject instances, typically just one though

TransitionReturn
(objects_to_write, objects_to_delete=None)[source] This is a simple class for capturing the response from a transition call
Parameters: - objects_to_write ([IDFObject]) – The list of IDFObject instances to be written as a result of this transition
- objects_to_delete ([ObjectTypeAndName]) – The list of idf object type/name combinations to be deleted as a result of this transition

TransitionRule
[source] This class is a must-override base class for defining transition rules for idf objects
-
get_name_of_object_to_transition
()[source] This method should be overridden in derived classes and return a single name of an object that this rule handles the transition for.
Returns: A string name of an object to transition Raises: UnimplementedMethodException – Raised if this method is called on the base class itself
-
get_names_of_dependent_objects
()[source] This method should be overridden in derived classes and return a list of object names that the derived transition implementation is dependent upon.
Returns: A list of string object names Raises: UnimplementedMethodException – Raised if this method is called on the base class itself
-
transition
(core_object, dependent_objects)[source] This method is the core transition operation for this object.
Parameters: - core_object – The original idf object to be transitioned
- dependent_objects – A dictionary of {object_name: [idf_object, ...]} containing the idf object data in the original idf that have object names defined in this derived classes get_names_of_dependent_objects method. Each key in this argument is a string object name, and each value is a list of all the idf objects in the file of that type.
Returns: A list of new IDFObject instances, typically just one though
Raises: UnimplementedMethodException – Raised if this method is called on the base class itself
