Method Detail

• copyRandomAccess

  RandomAccess<T> copyRandomAccess()

• setPositionAndGet

  default T setPositionAndGet(long... position)

  Convenience method that moves the RealRandomAccess to the given position and gets the value at that position. It's a shortcut for:

   
   setPosition( position );
   get();
   
   

  WARNING: The return value is invalidated by next call to setPositionAndGet(long...) or Positionable.setPosition(net.imglib2.Localizable).

   
   // This is wrong!!!
   a = randomAccess.setPositionAndGet( positionA );
   b = randomAccess.setPositionAndGet( positionB ); // this invalidates "a" !!!
   wrongDifference = a.getRealDouble() - b.getRealDouble();
  
   // Correct:
   // Use individual RandomAccesses to query a and b
   a = randomAccess_A.setPositionAndGet( positionA );
   b = randomAccess_B.setPositionAndGet( positionB ); // this is fine because a different RandomAccess is used
   difference = a.getRealDouble() - b.getRealDouble();
   
   

• setPositionAndGet

  default T setPositionAndGet(int... position)
