Class PostUpdateNode

A node associated with an object after an operation that might have changed its state.

This can be either the argument to a callable after the callable returns (which might have mutated the argument), or the qualifier of a field after an update to the field.

Nodes corresponding to AST elements, for example ExprNodes, usually refer to the value before the update with the exception of ObjectCreationNodes, which represents the value after the constructor has run.
