Utils

The Utils package in MetamEnTh serves as a collection of utility classes and methods designed to support various operations and functionalities required by other entities within the system. These utility methods encapsulate common, reusable logic, promoting code reusability, maintainability, and modularity throughout MetamEnTh.

EntityInsert

This class provides utility methods for adding entities to other entities that have a one-to-many relationship with the class of the entity being added

Behaviours (Methods)

• insert_zone(entity, zone: Zone, building: Building): this utility method adds a zone to entities that possess the zones attribute, e.g., room
• insert_building_entity(entity_list, entity, entity_type, entity_object): this utility method adds an entity to another entity, e.g., adding a room to a floor, adding a sensor to a room, etc.
• _insert_unique(name: str): this method is used by insert_building_entity when the entity to be added to another entity has to be unique

EntityRemover

This class provides utility methods for removing entities from other entities that have a one-to-many relationship with the class of the entity being removed

Parent Class

Behaviours (Methods)

• remove_building_entity(building_entity_list, entity, entity_type, entity_object): this utility method removes an entity from another entity, e.g., a room from a floor, a damper from a duct

StructureEntitySearch

Behaviours (Methods)

• search_by_id(entity_list, uid): searches an entity with the unique identifier, e.g., a meter from a list of meters
• search_by_name(entity_list, name): searches an entity with its name, e.g., a sensor from a list of sensors
• search(entity_list, search_terms): searches an entity from a list of entities using attributes and their values in a dictionary, e.g., searching for all temperature sensors with {'measure': SensorMeasure.TEMPERATURE }
• date_range_search(entity_list: Union[List[SensorData], List[TriggerHistory], List[MeterMeasure], List[WeatherData]], from_timestamp: str, to_timestamp: str): searches for time-series data given the start date and time and the end date and time
• search_structure_entity(entity_list, search_field, search_value): searches for entities using a single attribute and its corresponding value

StructureSearch

The StructureSearch class provides utility methods to search for structure-related entities.

Behaviours (Methods)

• search_by_id(entity_list, uid): searches a structure entity with the unique identifier, e.g., a room from a list of rooms on a floor
• search_by_name(entity_list, name): searches a structure entity with its name, e.g., an open space from a list of open spaces on a floor
• search_by_number(entity_list, name): searches a structure entity with its number, e.g., a floor from a list of floors in a building
• search(entity_list, search_terms): searches an entity from a list of structure entities using attributes and their values in a dictionary, e.g., searching for all external wall materials made of wood {'material_type': MaterialType.EX_WALL_WOOd }
• search_structure_entity(entity_list, search_field, search_value): searches for floors, rooms, open spaces, layers, and covers using a single attribute and its corresponding value
