module RuboCop
# A wrapper around patterns array to perform optimized search.
#
# For projects with a large set of rubocop todo files, most items in `Exclude`/`Include`
# are exact file names. It is wasteful to linearly check the list of patterns over and over
# to check if the file is relevant to the cop.
#
# This class partitions an array of patterns into a set of exact match strings and the rest
# of the patterns. This way we can firstly do a cheap check in the set and then proceed via
# the costly patterns check, if needed.
