#copy_to(other, options = {}) ⇒ Object

Copies the response-specific parts of this Blodsband::Riak::Response to other after having made other include Blodsband::Riak::Response.

Does not copy links or meta since they are value specific.

Parameters:

  • other (Object) —

    what we want to copy our response data to.

  • options (Hash) (defaults to: {}) —
    :except
    Array<:status, :vclock, :last_modified, :key, :bucket>

    an array of data not to copy.

Returns:
