DeltaChain class final
Append deltas against the materialized head while they pay; otherwise take a fresh snapshot. A delta "stops paying" when DeltaRatio fires, when maxChainDepth is reached, or after orEvery revisions since the last snapshot.

Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- maxChainDepth → int
-
Materialization-cost bound: at most this many deltas ever chain
before a snapshot resets the walk.
final
- orEvery → int
-
Hard snapshot cadence regardless of ratios.
final
- rolloverWhen → DeltaRatio
-
The economics rule: a delta that costs more than this fraction of
the full content takes a snapshot instead.
final
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toJson(
) → Map< String, Object?> -
Manifest echo, so chains stay self-describing.
override
-
toString(
) → String -
A string representation of this object.
