Public Class Methods

new (source, node_id, location, flags, operator_loc, variable)

Source

# File lib/prism/node.rb, line 6532
def initialize(source, node_id, location, flags, operator_loc, variable)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @operator_loc = operator_loc
  @variable = variable
end

Initialize a new EmbeddedVariableNode node.

type ()

Source

# File lib/prism/node.rb, line 6606
def self.type
  :embedded_variable_node
end

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

Public Instance Methods

=== (other)

Source

# File lib/prism/node.rb, line 6612
def ===(other)
  other.is_a?(EmbeddedVariableNode) &&
    (operator_loc.nil? == other.operator_loc.nil?) &&
    (variable === other.variable)
end

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

accept (visitor)

Source

# File lib/prism/node.rb, line 6542
def accept(visitor)
  visitor.visit_embedded_variable_node(self)
end

def accept: (Visitor visitor) -> void

child_nodes ()

Source

# File lib/prism/node.rb, line 6547
def child_nodes
  [variable]
end

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

Also aliased as: deconstruct

comment_targets ()

Source

# File lib/prism/node.rb, line 6557
def comment_targets
  [operator_loc, variable] #: Array[Prism::node | Location]
end

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

compact_child_nodes ()

Source

# File lib/prism/node.rb, line 6552
def compact_child_nodes
  [variable]
end

def compact_child_nodes: () -> Array

copy (node_id: self.node_id, location: self.location, flags: self.flags, operator_loc: self.operator_loc, variable: self.variable)

Source

# File lib/prism/node.rb, line 6562
def copy(node_id: self.node_id, location: self.location, flags: self.flags, operator_loc: self.operator_loc, variable: self.variable)
  EmbeddedVariableNode.new(source, node_id, location, flags, operator_loc, variable)
end

def copy: (?node_id: Integer, ?location: Location, ?flags: Integer, ?operator_loc: Location, ?variable: InstanceVariableReadNode | ClassVariableReadNode | GlobalVariableReadNode | BackReferenceReadNode | NumberedReferenceReadNode) -> EmbeddedVariableNode

deconstruct ()

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

Alias for: child_nodes

deconstruct_keys (keys)

Source

# File lib/prism/node.rb, line 6570
def deconstruct_keys(keys)
  { node_id: node_id, location: location, operator_loc: operator_loc, variable: variable }
end

def deconstruct_keys: (Array keys) -> { node_id: Integer, location: Location, operator_loc: Location, variable: InstanceVariableReadNode | ClassVariableReadNode | GlobalVariableReadNode | BackReferenceReadNode | NumberedReferenceReadNode }

inspect ()

Source

# File lib/prism/node.rb, line 6596
def inspect
  InspectVisitor.compose(self)
end

def inspect -> String

operator ()

Source

# File lib/prism/node.rb, line 6591
def operator
  operator_loc.slice
end

def operator: () -> String

operator_loc ()

Source

# File lib/prism/node.rb, line 6575
def operator_loc
  location = @operator_loc
  return location if location.is_a?(Location)
  @operator_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
end

attr_reader operator_loc: Location

save_operator_loc (repository)

Source

# File lib/prism/node.rb, line 6583
def save_operator_loc(repository)
  repository.enter(node_id, :operator_loc)
end

Save the operator_loc location using the given saved source so that it can be retrieved later.
