Attributes

Public Class Methods

new(source, node_id, location, flags, operator_loc, variable) click to toggle source

Initialize a new EmbeddedVariableNode node.

# File lib/prism/node.rb, line 6969
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
type() click to toggle source

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

end

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 7056
def ===(other)
  other.is_a?(EmbeddedVariableNode) &&
    (operator_loc.nil? == other.operator_loc.nil?) &&
    (variable === other.variable)
end

def accept: (Visitor visitor) -> void

# File lib/prism/node.rb, line 6979
def accept(visitor)
  visitor.visit_embedded_variable_node(self)
end

end
save_operator_loc(repository) click to toggle source

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