    • Method Detail

      • randomAccess

        public BiConvertedRandomAccess<A,​B,​C> randomAccess()
        Description copied from interface: RandomAccessible
        Create a random access sampler for integer coordinates.

        The returned random access covers as much of the domain as possible.

        Please note: RandomAccessibleIntervals have a finite domain (their Interval), so RandomAccessible.randomAccess() is only guaranteed to cover this finite domain. This may lead to unexpected results when using Views. In the following code 
         RandomAccessible<T> extended = Views.extendBorder( img )
 RandomAccessibleInterval<T> cropped = Views.interval( extended, img );
 RandomAccess<T> a1 = extended.randomAccess();
 RandomAccess<T> a2 = cropped.randomAccess();
        The access a1 on the extended image is valid everywhere. However, somewhat counter-intuitively, the access a2 on the extended and cropped image is only valid on the interval img to which the extended image was cropped. The access is only required to cover this interval, because it is the domain of the cropped image. Views attempts to provide the fastest possible access that meets this requirement, and will therefore strip the extension. To deal with this, if you know that you need to access pixels outside the domain of the RandomAccessibleInterval, and you know that the RandomAccessibleInterval is actually defined beyond its interval boundaries, then use the RandomAccessible.randomAccess(Interval) variant and specify which interval you actually want to access. In the above example, 
         RandomAccess<T> a2 = cropped.randomAccess( Intervals.expand( img, 10 ) );
        will provide the extended access as expected.
        Specified by:
        randomAccess in interface RandomAccessible<A>

        Returns:
        random access sampler

      • getDestinationType

        @Deprecated
public C getDestinationType()
        Deprecated.
        Use getDestinationSupplier() instead.
        Returns:
        an instance of the destination Type.

      • getDestinationSupplier

        public java.util.function.Supplier<? extends C> getDestinationSupplier()
        Returns:
        the supplier of conversion destination instances

      • getConverterSupplier

        public java.util.function.Supplier<BiConverter<? super A,​? super B,​? super C>> getConverterSupplier()
        Returns:
        the supplier of converter instances

      • getType

        public C getType()
        Description copied from interface: Typed
        Get an instance of T.

        It should not be assumed that the returned T instance is an independent copy. In particular, repeated calls to getType() may return the same instance.

        Returns:
        an instance of T
