Öffentliche Klassenmethoden

new (source, node_id, location, flags, locals, parameters, body, opening_loc, closing_loc)

Source

# File lib/prism/node.rb, line 1843
def initialize(source, node_id, location, flags, locals, parameters, body, opening_loc, closing_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @locals = locals
  @parameters = parameters
  @body = body
  @opening_loc = opening_loc
  @closing_loc = closing_loc
end

Initialisiert einen neuen BlockNode-Knoten.

def self.type
  :block_node
end

Gibt eine symbolische Darstellung dieses Knotentyps zurück. Siehe Node::type.

Öffentliche Instanzmethoden

=== (other)

Source

# File lib/prism/node.rb, line 1972
def ===(other)
  other.is_a?(BlockNode) &&
    (locals.length == other.locals.length) &&
    locals.zip(other.locals).all? { |left, right| left === right } &&
    (parameters === other.parameters) &&
    (body === other.body) &&
    (opening_loc.nil? == other.opening_loc.nil?) &&
    (closing_loc.nil? == other.closing_loc.nil?)
end

Implementiert die Fallgleichheit für den Knoten. Dies ist effektiv ==, aber ohne den Wert von Standorten zu vergleichen. Standorte werden nur auf Anwesenheit geprüft.

accept (visitor)

  visitor.visit_block_node(self)
end

def accept: (Visitor visitor) -> void

child_nodes ()

Source

# File lib/prism/node.rb, line 1861
def child_nodes
  [parameters, body]
end

def child_nodes: () -> Array

Auch bekannt als: deconstruct

closing ()

Source

# File lib/prism/node.rb, line 1951

end

Repräsentiert die Position des schließenden |.
