Method: Array#assimilate!

Defined in:
lib/rtkit/ruby_extensions.rb

#assimilate!(other) ⇒ Object

Rearranges the array (self) so that its elements appear in exactly the same sequence as another array (the argument). If the two arrays do not contain the same set of elements, an error is raised.

Examples

a = [5, 2, 10, 1]
b = [10, 2, 1, 5]
b.assimilate!(a)
b
=> [5, 2, 10, 1]

NB! Not in use atm!
