Detailed Description

Accessor that can dispatch to internal Accessors based on the entity type of IDs provided.

As the accessor includes batched access this class will batch entity IDs by type before using the internal accessors. This is needed as the EntityMetaDataAccessor implements queries against the page table base on entity IDs that won't work for all entities.
