TMap

trait TMap[A, B] extends AnyRef

A transactional map implementation that requires that all of its map-like operations be called from inside an atomic block. Rather than extending Map, an implicit conversion is provided from TMap to Map if the current scope is part of an atomic block (see TMap.asMap).

The keys (with type A) must be immutable, or at least not modified while they are in the map. The TMap implementation assumes that it can safely perform key equality and hash checks outside a transaction without affecting atomicity.
