Expand description

Trait containing all Asset methods.

Implementors

Asset, ClipAsset, Project, TrackElementAsset

Required methods

Extracts a new property::Asset::extractable-type object from the asset. The property::Asset::id of the asset may determine the properties and state of the newly created object.

Returns

A newly created object, or None if an error occurred.

Retrieve the error that was set on the asset when it was loaded.

Returns

The error set on asset, or None if no error occurred when asset was loaded.

Gets the property::Asset::extractable-type of the asset.

Returns

The extractable type of self.

Gets the property::Asset::id of the asset.

Returns

The ID of self.

Gets the default property::Asset::proxy of the asset.

Returns

The default proxy of self.

Gets the property::Asset::proxy-target of the asset.

Note that the proxy target may have loaded with an error, so you should call error() on the returned target.

Returns

The asset that self is a proxy of.

Get all the proxies that the asset has. The first item of the list will be the default property::Asset::proxy. The second will be the proxy that is ‘next in line’ to be default, and so on.

Returns

The list of proxies that self has.

Sets the property::Asset::proxy for the asset.

If proxy is among the existing proxies of the asset (see list_proxies()) it will be moved to become the default proxy. Otherwise, if proxy is not None, it will be added to the list of proxies, as the new default. The previous default proxy will become ‘next in line’ for if the new one is removed, and so on. As such, this will not actually remove the previous default proxy (use unproxy() for that).

Note that an asset can only act as a proxy for one other asset.

As a special case, if proxy is None, then this method will actually remove all proxies from the asset.

proxy

A new default proxy for self

Returns

true if proxy was successfully set as the default for self.

Removes the proxy from the available list of proxies for the asset. If the given proxy is the default proxy of the list, then the next proxy in the available list (see list_proxies()) will become the default. If there are no other proxies, then the asset will no longer have a default property::Asset::proxy.

proxy

An existing proxy of self

Returns

true if proxy was successfully removed from self’s proxy list.
