详细描述

Adapts integral AttributeSet base values to IResourceAccount.

The resource id is the AttributeSet attribute id. The adapter reads and writes the base value; modifiers remain AttributeSet projections and are intentionally not folded into an account balance. Attribute values used as resources must be finite, integral and non-negative. AttributeSet owns the balance; this adapter only owns active reservation bookkeeping.

The referenced AttributeSet is borrowed and must outlive this adapter. All operations are synchronous and must be called on the owner thread.
