--- !ruby/object:RI::MethodDescription aliases: [] block_params: comment: - !ruby/struct:SM::Flow::P body: Produces a shallow copy of <em>obj</em>---the instance variables of <em>obj</em> are copied, but not the objects they reference. <tt>dup</tt> copies the tainted state of <em>obj</em>. See also the discussion under <tt>Object#clone</tt>. In general, <tt>clone</tt> and <tt>dup</tt> may have different semantics in descendent classes. While <tt>clone</tt> is used to duplicate an object, including its internal state, <tt>dup</tt> typically uses the class of the descendent object to create the new instance. - !ruby/struct:SM::Flow::P body: "This method may have class-specific behavior. If so, that behavior will be documented under the #<tt>initialize_copy</tt> method of the class." full_name: Object#dup is_singleton: false name: dup params: | obj.dup -> an_object visibility: public
