Method Detail

• createLoop

  public static LongConsumer createLoop(Object action,
                                        List<? extends Cursor<?>> cursors)

  For example.: Given a BiConsumer and two Cursors:

   
  
   BiConsumer<A, B> biConsumer = ... ;
   Cursor<A> cursorA = ... ;
   Cursor<B> cursorB = ... ;
   
   

  This method createLoop(biConsumer, Arrays.asList(cursorA, cursorB)) will return a LongConsumer that is functionally equivalent to:

   
  
   LongConsumer loop = n -> {
       for ( long i = 0; i < n; i++ )
           biConsumer.accept( cursorA.next(), cursorB.next() );
   };
   
   

  The returned LongConsumer is created in a way, that it can be gracefully optimised by the Java just-in-time compiler.

  Parameters:

  action - This must be an instance of Consumer, BiConsumer, LoopBuilder.TriConsumer, LoopBuilder.FourConsumer, LoopBuilder.FiveConsumer or LoopBuilder.SixConsumer.

  cursors - A list of Cursor, the size of the list must fit given action.

  Throws:

  IllegalArgumentException - if the number of cursor does not fit the given consumer.
