# class Prism::EmbeddedVariableNode

Represents an interpolated variable.

    "foo #@bar"
         ^^^^^

### Attributes

variable [R]

attr_reader variable: `InstanceVariableReadNode` | `ClassVariableReadNode` | `GlobalVariableReadNode` | `BackReferenceReadNode` | `NumberedReferenceReadNode`

### Public Class Methods

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

    # File lib/prism/node.rb, line 6961
    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 7042
    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 7048
    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 6971
    def accept(visitor)
      visitor.visit_embedded_variable_node(self)
    end

def accept: (`Visitor` visitor) -> void

Also aliased as: deconstruct

operator_loc ()
Source

    # File lib/prism/node.rb, line 7011
    def operator_loc
      location = @operator_loc
      return location if location.is_a?(Location)
