A class which provides a method `each' to be used as an Enumerable object.
Creates a new Enumerable::Enumerator object, which is to be used as an Enumerable object using the given object's given method with the given arguments.
e.g.:
str = "xyz" enum = Enumerable::Enumerator.new(str, :each_byte) a = enum.map {|b| '%02x' % b } #=> ["78", "79", "7a"]
static VALUE enumerator_initialize(argc, argv, obj) int argc; VALUE *argv; VALUE obj; { VALUE enum_obj, enum_method, enum_args; rb_scan_args(argc, argv, "11*", &enum_obj, &enum_method, &enum_args); if (enum_method == Qnil) enum_method = sym_each; rb_ivar_set(obj, id_enum_obj, enum_obj); rb_ivar_set(obj, id_enum_method, enum_method); rb_ivar_set(obj, id_enum_args, enum_args); return Qnil; }
Iterates the given block using the object and the method specified in the first place.
static VALUE enumerator_each(obj) VALUE obj; { VALUE val; obj = (VALUE)rb_node_newnode(NODE_MEMO, rb_ivar_get(obj, id_enum_obj), rb_to_id(rb_ivar_get(obj, id_enum_method)), rb_ivar_get(obj, id_enum_args)); val = rb_iterate((VALUE (*)_((VALUE)))enumerator_iter, obj, rb_yield, 0); return val; }
