Overview
An attribute assignment method calls should be listed only once in a gemspec.
Assigning to an attribute with the same name using spec.foo =
or
spec.attribute#[]=
will be an unintended usage. On the other hand,
duplication of methods such # as spec.requirements
,
spec.add_runtime_dependency
, and others are permitted because it is
the intended use of appending values.

#add_range, | |
#arguments_range | A range containing the first to the last argument of a method call or method definition. |
#column_offset_between, | |
#contents_range | A range containing only the contents of a literal with delimiters (e.g. |
#directions, | |
#effective_column | Returns the column attribute of the range, except if the range is on the first line and there’s a byte order mark at the beginning of that line, in which case 1 is subtracted from the column value. |

#add_global_offense | Adds an offense that has no particular location. |
#add_offense | Adds an offense on the specified range (or node with an expression) Unless that offense is disabled for this range, a corrector will be yielded to provide the cop the opportunity to autocorrect the offense. |
#begin_investigation | Called before any investigation. |
#callbacks_needed, | |
#cop_config | Configuration Helpers. |
#cop_name, #excluded_file?, | |
#external_dependency_checksum | This method should be overridden when a cop’s behavior depends on state that lives outside of these locations: |

#message | Gets called if no message is specified when calling |

#offenses, | |
#on_investigation_end | Called after all on_… |
#on_new_investigation | Called before all on_… |
#on_other_file | Called instead of all on_… |
#parse | There should be very limited reasons for a Cop to do it’s own parsing. |
#parser_engine, | |
#ready | Called between investigations. |
#relevant_file?, | |
#target_gem_version | Returns a gems locked versions (i.e. |
#target_rails_version, #target_ruby_version, #annotate, #apply_correction, #attempt_correction, | |
