Examples of org.jruby.RubyObject

org.jruby.RubyObject
RubyObject is the only implementation of the {@link org.jruby.runtime.builtin.IRubyObject}. Every Ruby object in JRuby is represented by something that is an instance of RubyObject. In some of the core class implementations, this means doing a subclass that extends RubyObject, in other cases it means using a simple RubyObject instance and the data field to store specific information about the Ruby object. Some care has been taken to make the implementation be as monomorphic as possible, so that the Java Hotspot engine can improve performance of it. That is the reason for several patterns that might seem odd in this class. The IRubyObject interface used to have lots of methods for different things, but these have now mostly been refactored into several interfaces that gives access to that specific part of the object. This gives us the possibility to switch out that subsystem without changing interfaces again. For example, instance variable and internal variables are handled this way, but the implementation in RubyObject only returns "this" in {@link #getInstanceVariables()} and{@link #getInternalVariables()}. @author jpetersen
