copySpecialInstanceVariables

public void copySpecialInstanceVariables(IRubyObject clone)

Description copied from class: RubyBasicObject

Lots of MRI objects keep their state in non-lookupable ivars (e:g. Range, Struct, etc). This method is responsible for dupping our java field equivalents

Specified by:

copySpecialInstanceVariables in interface IRubyObject

Overrides:

copySpecialInstanceVariables in class RubyBasicObject

public IRubyObject op_equal(ThreadContext context,

inspect

public IRubyObject inspect(ThreadContext context)

to_a

public RubyArray to_a()

Description copied from class: RubyBasicObject

rb_any_to_a call-seq: obj.to_a -> anArray Returns an array representation of obj. For objects of class Object and others that don't explicitly override the method, the return value is an array containing self. However, this latter behavior will soon be obsolete. self.to_a #=> -:1: warning: default `to_a' will be obsolete "hello".to_a #=> ["hello"] Time.new.to_a #=> [39, 54, 8, 9, 4, 2003, 3, 99, true, "CDT"] The default to_a method is deprecated.

Overrides:

to_a in class RubyBasicObject

to_h

                                throws IOException

Throws:

IOException

initialize_copy

public IRubyObject initialize_copy(IRubyObject arg)

Description copied from class: RubyBasicObject

rb_obj_init_copy Initializes this object as a copy of the original, that is the parameter to this object. Will make sure that the argument actually has the same real class as this object. It shouldn't be possible to initialize an object with something totally different.

Overrides:

initialize_copy in class RubyBasicObject
