Public Class Methods

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

(Source source, Integer node_id, Location location, Integer flags, Location operator_loc, (InstanceVariableReadNode | ClassVariableReadNode | GlobalVariableReadNode | BackReferenceReadNode | NumberedReferenceReadNode) variable) → void

Source

# File lib/prism/node.rb, line 10958
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.

Public Instance Methods

variable → InstanceVariableReadNode | ClassVariableReadNode | GlobalVariableReadNode | BackReferenceReadNode | NumberedReferenceReadNode

() → (InstanceVariableReadNode | ClassVariableReadNode | GlobalVariableReadNode | BackReferenceReadNode | NumberedReferenceReadNode)

Source

# File lib/prism/node.rb, line 11082
def variable
  @variable
end

Returns the variable attribute.

Locations

Public Instance Methods

operator_loc → Location

() → Location

Source
