public IRubyObject
op_equal(ThreadContext context, IRubyObject obj)

Overrides org.jruby.ext.ffi.Pointer.op_equal.

Implements org.jruby.runtime.builtin.IRubyObject.op_equal.

rb_obj_equal Will by default use identity equality to compare objects.

public final String
toString()

Overrides org.jruby.RubyObject.toString.

The default toString method is just a wrapper that calls the Ruby "to_s" method.

Doc from org.jruby.RubyBasicObject.op_equal.

rb_obj_equal Will by default use identity equality to compare objects. This follows the Ruby semantics. The name of this method doesn't follow the convention because hierarchy problems
