• bootstrap

  public static Object bootstrap(MethodHandles.Lookup lookup,String methodName,TypeDescriptor type,Class<?> recordClass,String names,MethodHandle... getters) throwsThrowable

  Bootstrap method to generate theObject.equals(Object),Object.hashCode(), andObject.toString() methods, based on a description of the component names and accessor methods, for eitherinvokedynamic call sites or dynamic constant pool entries. For more detail on the semantics of the generated methods see the specification ofRecord.equals(Object),Record.hashCode() andRecord.toString().

  Parameters:

  lookup - Every bootstrap method is expected to have alookup which usually represents a lookup context with the accessibility privileges of the caller. This is becauseinvokedynamic call sites always provide alookup to the corresponding bootstrap method, but this method just ignores thelookup parameter

  methodName - the name of the method to generate, which must be one of"equals","hashCode", or"toString"

  type - aMethodType corresponding the descriptor type for the method, which must correspond to the descriptor for the correspondingObject method, if linking aninvokedynamic call site, or the constantMethodHandle.class, if linking a dynamic constant

  recordClass - the record class hosting the record components

  names - the list of component names, joined into a string separated by ";", or the empty string if there are no components. This parameter is ignored if themethodName parameter is"equals" or"hashCode"

  getters - method handles for the accessor methods for the components

  Returns:

  a call site if invoked by indy, or a method handle if invoked by a condy

  Throws:

  IllegalArgumentException - if the bootstrap arguments are invalid or inconsistent

  NullPointerException - if any argument isnull or if any element in thegetters array isnull

  Throwable - if any exception is thrown during call site construction
