Public Class Methods

new(source, node_id, location, flags, name, name_loc, operator_loc, value) click to toggle source

Initialize a new InstanceVariableOrWriteNode node.

# File lib/prism/node.rb, line 8689
def initialize(source, node_id, location, flags, name, name_loc, operator_loc, value)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @name = name
  @name_loc = name_loc
  @operator_loc = operator_loc
  @value = value
end

type() click to toggle source

Return a symbol representation of this node type. See ‘Node::type`.

Public Instance Methods

===(other) click to toggle source

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

# File lib/prism/node.rb, line 8773
def ===(other)
  other.is_a?(InstanceVariableOrWriteNode) &&
    (name === other.name) &&
    (name_loc.nil? == other.name_loc.nil?) &&
    (operator_loc.nil? == other.operator_loc.nil?) &&
    (value === other.value)
end

accept(visitor) click to toggle source

def accept: (Visitor visitor) -> void

# File lib/prism/node.rb, line 8701
def accept(visitor)
  visitor.visit_instance_variable_or_write_node(self)
end

child_nodes() click to toggle source

def child_nodes: () -> Array[nil | Node]

# File lib/prism/node.rb, line 8706
def child_nodes
  [value]
end

Also aliased as: deconstruct

comment_targets() click to toggle source

def comment_targets: () -> Array[Node | Location]

# File lib/prism/node.rb, line 8716
def comment_targets
  [name_loc, operator_loc, value] #: Array[Prism::node | Location]

end

deconstruct()

def deconstruct: () -> Array[nil | Node]

Alias for: child_nodes
