class espnet3.publication.demo.assets.UIAssetRegistry(assets: dict[str, UIAsset] | None = None)

Bases: object

Registry of named UI asset definitions.

The registry maps type strings from demo configs to concrete UIAsset instances. A demo session clones the default registry so built-in asset definitions stay isolated from per-session state.

Initialize with an optional pre-populated asset mapping.

clone() → UIAssetRegistry

Return a shallow copy for one demo session.

get(name: str) → UIAsset

Return one registered asset.

• Parameters:name – Asset type name from demo config.
• Returns: Registered asset instance.
• Return type:UIAsset
• Raises:KeyError – If the asset type is unknown.

register(name: str, asset: UIAsset | type[UIAsset], replace: bool = False) → None

Register one asset definition.

• Parameters:
  • name – Config-facing asset name such as "audio" or "prompt_text".
  • asset – Asset instance or asset subclass to register.
  • replace – Whether an existing registration may be overwritten.
• Raises:
  • ValueError – If name is already registered and replace is False.
  • TypeError – If asset is neither a UIAsset instance nor a UIAsset subclass.
