  • Method Details

    • jumpFwd

      public void jumpFwd(long steps)
      Description copied from interface: Iterator
      Move steps × forward.

      Highly recommended to override this with a more efficient version.

      Specified by:
      jumpFwd in interface Iterator
      Parameters:
      steps - number of steps to move forward

    • fwd

      public void fwd()
      Description copied from interface: Iterator
      Move forward.
      Specified by:
      fwd in interface Iterator

    • reset

      public void reset()
      Description copied from interface: Iterator
      Reset the Iterator, that is put it to where it would be if newly created.
      Specified by:
      reset in interface Iterator

    • hasNext

      public boolean hasNext()
      Description copied from interface: Iterator
      Returns true if another step forward is possible.
      Specified by:
      hasNext in interface Iterator
      Returns:
      true, if there is another step forward is possible, otherwise false

    • get

      public T get()
      Description copied from interface: Sampler
      Access the actual T instance providing access to a pixel, sub-pixel or integral region value the Sampler points at.
      Specified by:
      get in interface Sampler<T>

    • getType

      public T 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.

      Specified by:
      getType in interface Sampler<T>
      Specified by:
      getType in interface Typed<T>
      Returns:
      an instance of T

    • copy

      public Sampler<T> copy()
      Specified by:
      copy in interface Sampler<T>
      Returns:
      - A new Sampler in the same state accessing the same values. It does NOT copy T, just the state of the Sampler. Otherwise use T.copy() if available. Sampler.copy().get() == Sampler.get(), i.e. both hold the same value, not necessarily the same instance (this is the case for an ArrayCursor for example)

    • setRandomAccess

      public void setRandomAccess(RandomAccess<T> srcAccess)
      Specified by:
      setRandomAccess in interface ProjectedSampler<T>
      Parameters:
      srcAccess - sets the random access from which the sampler takes the values of the projected dimension
