Public Class Methods
Initialize a new PinnedVariableNode
node.
# File lib/prism/node.rb, line 14254 def initialize(source, node_id, location, flags, variable, operator_loc) @source = source @node_id = node_id @location = location @flags = flags @variable = variable @operator_loc = operator_loc 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.
