Class Method Details

.type ⇒ Object

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

end

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 13828

def ===(other)
  other.is_a?(MissingNode)
end

#accept(visitor) ⇒ Object

def accept: (Visitor visitor) -> void

# File 'lib/prism/node.rb', line 13773

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

#child_nodes ⇒ Object Also known as: deconstruct

def child_nodes: () -> Array

# File 'lib/prism/node.rb', line 13778

def child_nodes
  []
end

#comment_targets ⇒ Object

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

# File 'lib/prism/node.rb', line 13794

def comment_targets
  [] #: Array[Prism::node | Location]
end

#compact_child_nodes ⇒ Object

def compact_child_nodes: () -> Array

# File 'lib/prism/node.rb', line 13789

def compact_child_nodes
  []
end

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

def copy: (?node_id: Integer, ?location: Location, ?flags: Integer) -> MissingNode

# File 'lib/prism/node.rb', line 13799

def copy(node_id: self.node_id, location: self.location, flags: self.flags)
  MissingNode.new(source, node_id, location, flags)
end

#deconstruct_keys(keys) ⇒ Object

def deconstruct_keys: (Array keys) -> { node_id: Integer, location: Location }

# File 'lib/prism/node.rb', line 13807

def deconstruct_keys(keys)
  { node_id: node_id, location: location }
end

#each_child_node ⇒ Object

def each_child_node: () { (Prism::node) -> void } -> void | () -> Enumerator

# File 'lib/prism/node.rb', line 13783

def each_child_node
  return to_enum(:each_child_node) unless block_given?

end

#inspect ⇒ Object

def inspect -> String

# File 'lib/prism/node.rb', line 13812

def inspect
  InspectVisitor.compose(self)
end

#type ⇒ Object

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