Module: SimpleCov::Combine::InternedCounts

Extended by:
InternedCounts
Included in:
InternedCounts
Defined in:
lib/simplecov/combine/interned_counts.rb

Overview

The inner merge loop the branches and methods combiners share: folds source's tuple => count pairs into target, an interned table keyed by each tuple's merge identity and holding [raw_key, count] pairs. The first-seen raw key is kept for display; counts sum. target and its pairs are always built by this loop, so updating them in place can't reach data a caller still holds.
