Method: RuboCop::Cop::Base#external_dependency_checksum

Defined in:

lib/rubocop/cop/base.rb

#external_dependency_checksum ⇒ Object

This method should be overridden when a cop’s behavior depends on state that lives outside of these locations:

(1) the file under inspection
(2) the cop's source code
(3) the config (eg a .rubocop.yml file)

For example, some cops may want to look at other parts of the codebase being inspected to find violations. A cop may use the presence or absence of file ‘foo.rb` to determine whether a certain violation exists in `bar.rb`.

Overriding this method allows the cop to indicate to RuboCop’s ResultCache system when those external dependencies change, ie when the ResultCache should be invalidated.
