final case class MetaInformationUpdate[V](value: V) extends SomeUpdate[V] with Product with Serializable

Characterizes an update that did not affect the abstract state but instead just updated some meta information.

In general, the abstract interpretation framework handles NoUpdates and MetaInformationUpdates in the same way.

Example

If two values are merged that are seen on two different paths, but which represent the same abstract value, we may want to update the meta-information about the origin of the current value, but this information may not be part of the abstract state and hence, is not relevant for the abstract interpreter. In this case the interpreter will not reschedule subsequent instructions. However, whether or not the information about the origin of a value is considered to be part of the abstract state is a decision of the domain.
