attr_reader expression: Prism::node?

### Public Class Methods

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

Initialize a new `SplatNode` node.

    # File prism/node.rb, line 16671
    def initialize(source, node_id, location, flags, operator_loc, expression)
      @source = source
      @node_id = node_id
      @location = location
      @flags = flags
      @operator_loc = operator_loc
      @expression = expression
    end

type() click to toggle source

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

    # File prism/node.rb, line 16747
    def self.type
      :splat_node
    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 prism/node.rb, line 16753
    def ===(other)
      other.is_a?(SplatNode) &&
        (operator_loc.nil? == other.operator_loc.nil?) &&
        (expression === other.expression)
    end

accept(visitor) click to toggle source

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

    # File prism/node.rb, line 16681
    def accept(visitor)
      visitor.visit_splat_node(self)
    end

child_nodes() click to toggle source

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

    # File prism/node.rb, line 16686
    def child_nodes
      [expression]
    end

Also aliased as: deconstruct
comment_targets() click to toggle source

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

    # File prism/node.rb, line 16698
    def comment_targets
      [operator_loc, *expression] #: Array[Prism::node | Location]
    end

compact_child_nodes() click to toggle source

def `compact_child_nodes`: () -> Array

    # File prism/node.rb, line 16691
    def compact_child_nodes
      compact = [] #: Array[Prism::node]
      compact << expression if expression
      compact
    end

copy(node_id: self.node_id, location: self.location, flags: self.flags, operator_loc: self.operator_loc, expression: self.expression) click to toggle source

def copy: (?node_id: Integer, ?location: `Location`, ?flags: Integer, ?operator_loc: `Location`, ?expression: Prism::node?) -> `SplatNode`

    # File prism/node.rb, line 16703
    def copy(node_id: self.node_id, location: self.location, flags: self.flags, operator_loc: self.operator_loc, expression: self.expression)
      SplatNode.new(source, node_id, location, flags, operator_loc, expression)
    end

deconstruct()

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

Alias for: child_nodes
deconstruct_keys(keys) click to toggle source

def `deconstruct_keys`: (Array keys) -> { node_id: Integer, location: `Location`, `operator_loc`: `Location`, expression: Prism::node? }

    # File prism/node.rb, line 16711
    def deconstruct_keys(keys)
      { node_id: node_id, location: location, operator_loc: operator_loc, expression: expression }
    end

inspect() click to toggle source

def inspect -> String

    # File prism/node.rb, line 16737
    def inspect
      InspectVisitor.compose(self)
    end

operator() click to toggle source

def operator: () -> String

    # File prism/node.rb, line 16732
    def operator
      operator_loc.slice
    end

operator_loc() click to toggle source

attr_reader `operator_loc`: `Location`

    # File prism/node.rb, line 16716
    def operator_loc
      location = @operator_loc
      return location if location.is_a?(Location)
      @operator_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
    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.

    # File prism/node.rb, line 16724

    def type
      :splat_node
