This cop checks that the ABC size of methods is not higher than the configured maximum. The ABC size is based on assignments, branches (method calls), and conditions. See http://c2.com/cgi/wiki?AbcMetric

This cop checks if the length of a method exceeds some maximum value. Comment lines can optionally be ignored. The maximum allowed length is configurable.

Method start has 31 lines of code (exceeds 25 allowed). Consider refactoring.

    This cop checks if the length of a block exceeds some maximum value. Comment lines can optionally be ignored. The maximum allowed length is configurable. The cop can be configured to ignore blocks passed to certain methods.

    Missing top-level class documentation comment.
    Open

        class Reactor
    Severity: Minor
    Found in lib/nio/websocket/reactor.rb by rubocop

    This cop checks for missing top-level documentation of classes and modules. Classes with no body are exempt from the check and so are namespace modules - modules that have nothing in their bodies except classes, other modules, or constant definitions.

    The documentation requirement is annulled if the class or module has a "#:nodoc:" comment next to it. Likewise, "#:nodoc: all" does the same for all its children.

    Example:

    # bad
class Person
  # ...
end

# good
# Description/Explanation of Person class
class Person
  # ...
end

"No string interpolation"
"Just text"

    Example: EnforcedStyle: double_quotes

"No special chars or interpolation"
"Every string in #{project} uses double_quotes"

    Severity: Minor
    Found in lib/nio/websocket/reactor.rb by rubocop

    This cop checks for rescuing StandardError. There are two supported styles implicit and explicit. This cop will not register an offense if any error other than StandardError is specified.

    Example: EnforcedStyle: implicit

    # `implicit` will enforce using `rescue` instead of
# `rescue StandardError`.

  foo
rescue StandardError
  bar

    # `explicit` will enforce using `rescue StandardError`
# instead of `rescue`.
