Constructor Details

This class inherits a constructor from SimpleCov::Filter

Instance Method Details

#matches?(source_file) ⇒ Boolean

Returns true when the given source file's filename matches the string configured when initializing this Filter with StringFilter.new('somestring'). Matching is path-segment-aware: the argument must appear immediately after a "/" and be followed by "/" or end-of-string, so "lib" matches "/lib/foo.rb" but not "/app/models/library.rb".
