Instance Method Details

#===(other) ⇒ Object

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 18018

def ===(other)
  other.is_a?(SplatNode) &&
    (operator_loc.nil? == other.operator_loc.nil?) &&
    (expression === other.expression)
end

#accept(visitor) ⇒ Object

def accept: (Visitor visitor) -> void

# File 'lib/prism/node.rb', line 17939

def accept(visitor)
  visitor.visit_splat_node(self)
end

#child_nodes ⇒ Object Also known as: deconstruct

# File 'lib/prism/node.rb', line 17963

def comment_targets
  [operator_loc, *expression] #: Array[Prism::node | Location]
end

#compact_child_nodes ⇒ Object

def compact_child_nodes: () -> Array

# File 'lib/prism/node.rb', line 17956

def compact_child_nodes
  compact = [] #: Array[Prism::node]

  compact
end

#copy(node_id: self.node_id, location: self.location, flags: self.flags, operator_loc: self.operator_loc, expression: self.expression) ⇒ Object

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

# File 'lib/prism/node.rb', line 17968

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

  { node_id: node_id, location: location, operator_loc: operator_loc, expression: expression }
end

#each_child_node {|expression| ... } ⇒ Object

def operator_loc
  location = @operator_loc
  return location if location.is_a?(Location)
  @operator_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
end
