def merge(left: T, right: T): T

By assumption: associative, commutative, idempotent.

By assumption: associative, commutative, idempotent.

Implementation note: If it matters, assume that left is the current state and right is an added delta. All code should assume that left is the larger state (and optimize for this). If left == right, prefer to return left.

Attributes

override def subsumption(left: T, right: T): Boolean

Subsumption states that left <= right in the sense that everything information in left is already contained in right. Overriding implementations must make sure that they compute exactly the same results as the equation below.
