Class Method Summary

.new(source, node_id, location, flags, else_keyword_loc, statements, end_keyword_loc) ⇒ ElseNode constructor

Initialize a new ElseNode node.
.type

Return a symbol representation of this node type.

`Node` - Inherited

.fields	Returns a list of the fields that exist for this node class.
.type	Similar to #type, this method returns a symbol that you can use for splitting on the type of the node without having to do a long === chain.
