Overview

Common base class for array-like collections that have lookup methods to avoid instantiating the elements if you only use the lookup method

your class should implement to_a

Instance Method Summary collapse

Methods included from Enumerable

#all_groups, #all_members, #command, #command!, #decrease, #down, #equipments, #fast_forward, #groups, #increase, #locations, #member_of, #members, #move, #next, #not_member_of, #not_tagged, #off, #on, #pause, #play, #points, #previous, #refresh, #rewind, #stop, #tagged, #toggle, #up, #update, #update!

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args, &block) ⇒ Object

Delegate any other methods to the actual array, exclude mutating methods
