TPropertyValueStorage

Templated storage for any initial value type, templated on the same parameter as [TPropertyComponents](API\Runtime\MovieScene\TPropertyComponents) for correct retrieval of resolved properties Initial values are stored as a sparse array, with stable indices that uniquely identify the value.

API > API/Runtime > API/Runtime/MovieScene

Templated storage for any initial value type, templated on the same parameter as TPropertyComponents for correct retrieval of resolved properties Initial values are stored as a sparse array, with stable indices that uniquely identify the value. A look-up-table exists for finding indices based on an object and resolved property.
