# File 'activesupport/lib/active_support/deprecation/deprecators.rb', line 16

def [](name)
  @deprecators[name]
end

#[]=(name, deprecator)

Adds a given ActiveSupport.deprecator to this collection. The deprecator will be immediately configured with any options previously set on this collection.

deprecators = ActiveSupport::Deprecation::Deprecators.new
deprecators.debug = true

foo_deprecator = ActiveSupport::Deprecation.new("2.0", "Foo")
foo_deprecator.debug    # => false

deprecators[:foo] = foo_deprecator
deprecators[:foo].debug # => true

def []=(name, deprecator)

end

#each(&block)

Iterates over all deprecators in this collection. If no block is given, returns an Enumerator.
