Öffentliche Instanzmethoden

=== (other)

Source

# File lib/prism/node.rb, line 1643
def ===(other)
  other.is_a?(BeginNode) &&
    (begin_keyword_loc.nil? == other.begin_keyword_loc.nil?) &&
    (statements === other.statements) &&
    (rescue_clause === other.rescue_clause) &&
    (else_clause === other.else_clause) &&
    (ensure_clause === other.ensure_clause) &&
    (end_keyword_loc.nil? == other.end_keyword_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)

Source

# File lib/prism/node.rb, line 1511
def accept(visitor)
  visitor.visit_begin_node(self)
end

def accept: (Visitor visitor) -> void

begin_keyword ()

  when nil
    nil
  when Location
    location
  else
    @begin_keyword_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)

end

Stellt die Position des Schlüsselworts begin dar.
