◆ unlink()

void unlink ( )

protectedvirtual

release all links to other Asset objects held internally.

release all links to other dependent asset objects held internally and advise all parent assets to do so with the link to this asset.

The lifecycle of Asset objects is managed by smart pointers and the Asset manager. Calling unlink() breaks interconnections to other Assets in the central Object network comprising the session. Especially, the downward links to dependent entities are released, while the primary (upward) smart-ptr links to our prerequisites are still retained. The rationale is, after releasing these redundant or cyclic interlinking, when the AssetManager removes its DB entry for this asset, the smart pointer goes out of scope and causes unwinding of the whole dependency chain.

Note: we don't release upward links to parent assets, thus effectively keeping the parents alive, because frequently the accessibility of parent assets is part of our own contract. (e.g. media for clip assets)

Reimplemented from Asset.
