StateRecord

StateRecord()

StateRecord(snapshotId: Int)

abstract fun assign(value: StateRecord): Unit

Copy the value into this state record from another for the same state object.

abstract fun create(): StateRecord

Create a new state record for the same state object. Consider also implementing the create overload that provides snapshotId for faster record construction when snapshot id is known.

open fun create(snapshotId: Int): StateRecord

Create a new state record for the same state object and provided snapshotId. This allows to implement an optimized version of create to avoid accessing currentSnapshot when snapshot id is known. The default implementation provides a backwards compatible behavior, and should be overridden if StateRecord subclass supports this optimization.
