Tracktable Trajectory Library - Domains module

Here you will find the modules containing point, trajectory and reader types for each different point domain.

tracktable.domain.domain_class(domain_name, class_name)

Fetch the class object for a named class in a named domain

Given the name of a Tracktable domain (terrestrial, cartesian2d, cartesian3d, feature_vectores) and the name of a class (BasePoint, TrajectoryPoint, Trajectory, BoundingBox), return the class object so that you can instantiate it.

Parameters

• {string} (class_name) – Name of point domain. Must be one of “terrestrial”, “cartesian2d”, “cartesian3d”, or “feature_vectors”.

• {string} – Name of class. Must be one of “BasePoint”, “TrajectoryPoint”, “Trajectory”, or “BoundingBox”.

Returns

Class object for the specified class.

Raises

AttributeError – you specified a domain or a class that doesn’t exist

tracktable.domain.domain_class_for_object(thing: object, class_name: string) → class object

Given a Tracktable object (point, trajectory point, trajectory or bounding box) and the name of a related class, return the class object for that related class.

This helps you retrieve related classes for a domain object if you don’t know the domain a priori. For example, if the user wants a bounding box for some arbitrary trajectory, you can ask for “whatever BoundingBox type corresponds to this object”.

Parameters

• thing (object) – Tracktable domain object

• desired_class (string) – Name of desired class

Returns

Class object for the requested class

Raises

AttributeError – you supplied an object that does not have a ‘domain’ attribute or asked for a domain class that does not exist

tracktable.domain.domain_module_for_object(thing: object) → domain module

Given a Tracktable object (point, trajectory point, trajectory or bounding box), return the module for that object’s point domain.

This helps you retrieve related classes for a domain object if you don’t know the domain a priori.

Parameters

thing (object) – Tracktable domain object

Returns

Module object for that point’s domain

Raises

AttributeError – you supplied an object that does not have a ‘domain’ attribute

tracktable.domain.domain_module_from_name(name: string) → domain module

Given the name of one of Tracktable’s point domains (terrestrial, cartesian2d, cartesian3d), return the module object for that domain.

This helps you retrieve related classes for a domain object when you don’t know the domain a priori.

Parameters

[string] (_domain) – Name of point domain

Returns

Module object for specified domain

Raises

AttributeError – you’ve asked for a domain that doesn’t exist
