Class Method Summary

.new(source, node_id, location, flags, name, name_loc, operator_loc) ⇒ RestParameterNode constructor

Initialize a new RestParameterNode 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.

Instance Attribute Summary

#name readonly

attr_reader name: Symbol?
#repeated_parameter? ⇒ Boolean readonly

def repeated_parameter?: () -> bool.

`Node` - Inherited

#newline?	Returns true if the node has the newline flag set.
#node_id	A unique identifier for this node.
#static_literal?	Returns true if the node has the static literal flag set.
