Known direct subtypes
Gets a control flow node that updates the targeted assignable when reached.
Gets a first read of the same underlying assignable. That is, a read that can be reached from this definition without passing through any other reads, and which is guaranteed to read the value assigned in this definition. Example:
Gets a reachable read of the same underlying assignable. That is, a read that can be reached from this definition, and which is guaranteed to read the value assigned in this definition.

Gets the enclosing callable of this definition.
Gets the underlying expression that updates the targeted assignable when reached, if any.
Gets the location of this assignable definition.
