Class: DeepCover::Node::Masgn

Inherits:
DeepCover::Node show all
Defined in:
lib/deep_cover/node/assignments.rb

Overview

Some multiple assignments are the only cases where Ruby syntax rules won’t allow us to insert tracking code where we’d like it to be run.

For example:

method.a, b, method_2.c = [...]

We’d like to add a tracker after the call to ‘a=` and before the assignment to b and the call to `method_2`.

We can’t really do this with simple insertions, so we temporarily of strategy for BackwardsStrategy
