Method Details [hide private]

instantiate(cls, owner, id, url, frame_of_reference, *args)
Class Method

source code 

Factory method to create an instance from backend data.

This method expect the exact data from the backend, so it does not need to be tolerant or to check consistency (the backend is assumed to be sane).

Overrides: element.PackageElement.instantiate
(inherited documentation)

create_new(cls, owner, id, url, frame_of_reference, *a)
Class Method

source code 

Factory method to create a new instance both in memory and backend.

This method will usually perform checks and conversions from its actual arguments to the data expected to the backend. It is responsible for 1/ storing the data in the backend and 2/ initializing the instance (for which it should reuse instantiate to reduce redundancy).

Note that this method *should* be tolerant w.r.t. its parameters, especially accepting both element instances or ID-refs.

NB: this method does nothing and must not be invoked by superclasses (indeed, it raises an exception).

Overrides: element.PackageElement.create_new
(inherited documentation)

_get_url(self)

source code 

The URL from which the media can be fetched.

Decorators:
  • @autoproperty

source code 
Decorators:
  • @autoproperty

_get_unit(self)

source code 

The time-unit of this media if known, else None.

The unit is known if the frame of reference is in the default Advene namespace.

NB: this is specific to the cinelab application model.

Decorators:
  • @autoproperty

_get_origin(self)

source code 

The time-origin of this media if known, else None.

The origin is known if the frame of reference is in the default Advene namespace.

NB: this is specific to the cinelab application model.

Decorators:
  • @autoproperty
