class Prism::CapturePatternNode
Represents assigning to a local variable in pattern matching.
foo => [bar => baz] ^^^^^^^^^^^^
Attributes
attr_reader target: LocalVariableTargetNode
attr_reader value: Prism::node
Public Class Methods
Initialize a new CapturePatternNode
node.
# File lib/prism/node.rb, line 2911 def initialize(source, node_id, location, flags, value, target, operator_loc) @source = source @node_id = node_id @location = location @flags = flags @value = value @target = target @operator_loc = operator_loc end
Return a symbol representation of this node type. See ‘Node::type`.
# File lib/prism/node.rb, line 2983 def self.type :capture_pattern_node end
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.
