Binding objects can be created using <tt>Kernel#binding</tt>, and are made available to the callback of <tt>Kernel#set_trace_func</tt>. - !ruby/struct:SM::Flow::P body: These binding objects can be passed as the second argument of the <tt>Kernel#eval</tt> method, establishing an environment for the evaluation. - !ruby/struct:SM::Flow::VERB body: " class Demo\n def initialize(n)\n @secret = n\n end\n def getBinding\n return binding()\n end\n end\n\n k1 = Demo.new(99)\n b1 = k1.getBinding\n k2 = Demo.new(-3)\n b2 = k2.getBinding\n\n eval(&quot;@secret&quot;, b1) #=&gt; 99\n eval(&quot;@secret&quot;, b2) #=&gt; -3\n eval(&quot;@secret&quot;) #=&gt; nil\n" - !ruby/struct:SM::Flow::P body: Binding objects have no class-specific methods. constants: [] full_name: Binding includes: [] instance_methods: - !ruby/object:RI::MethodSummary name: clone - !ruby/object:RI::MethodSummary name: eval name: Binding superclass: Object
