org.litebridgedb.tracking.ChangedCollectionField

public final class ChangedCollectionField
extends ChangedField

List-specific type of ChangedField which holds a snapshot of the original underlying map.

It inherits the common properties and behavior from the ChangedField class and extends it by including a snapshot of the original map associated with the field.

It ensures that the map snapshot is immutable.
