class Prism::WhileNode
Represents the use of the while
keyword, either in the block form or the modifier form.
bar while foo ^^^^^^^^^^^^^ while foo do bar end ^^^^^^^^^^^^^^^^^^^^
Attributes
attr_reader predicate: Prism::node
attr_reader statements: StatementsNode
?
Public Class Methods
Initialize a new WhileNode
node.
# File lib/prism/node.rb, line 17698 def initialize(source, node_id, location, flags, keyword_loc, closing_loc, predicate, statements) @source = source @node_id = node_id @location = location @flags = flags @keyword_loc = keyword_loc @closing_loc = closing_loc @predicate = predicate @statements = statements end
Return a symbol representation of this node type. See Node::type
.

Public Instance Methods
Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.
