f:Rn→T

A function over real space that can create a random access Sampler.

If your algorithm takes a RealRandomAccessible, this usually means that you expect that the domain is infinite. (In contrast to this, RealRandomAccessibleRealIntervals have a finite domain.)

Similarly to a RandomAccessible, a RealRandomAccessible might be defined only partially within the space.

  • Method Details

    • realRandomAccess

      RealRandomAccess<T> realRandomAccess()
      Create a random access sampler for real coordinates.
      Returns:
      random access sampler

    • realRandomAccess

      RealRandomAccess<T> realRandomAccess(RealInterval interval)

    • getAt

      default T getAt(float... position)
      Convenience method to query a RealRandomAccessible for the value at a position.

      WARNING: This method is VERY SLOW, and memory inefficient when used in tight loops, or called many times!!! Use realRandomAccess() when efficiency is important.

      This method is a short cut for realRandomAccess().setPositionAndGet( position );

      Parameters:
      position - , length must be ≥ EuclideanSpace.numDimensions()
      Returns:
      value of the the RandomAccessible at position.

    • getAt

      default T getAt(double... position)
      Convenience method to query a RealRandomAccessible for the value at a position.

      WARNING: This method is VERY SLOW, and memory inefficient when used in tight loops, or called many times!!! Use realRandomAccess() when efficiency is important.

      This method is a short cut for realRandomAccess().setPositionAndGet( position );

      Parameters:
      position - , length must be ≥ EuclideanSpace.numDimensions()
      Returns:
      value of the the RandomAccessible at position.

    • getAt

      default T getAt(RealLocalizable position)
      Convenience method to query a RealRandomAccessible for the value at a position.

      WARNING: This method is VERY SLOW, and memory inefficient when used in tight loops, or called many times!!! Use realRandomAccess() when efficiency is important.

      This method is a short cut for realRandomAccess().setPositionAndGet( position );

      Parameters:
      position - , EuclideanSpace.numDimensions() must be ≥ EuclideanSpace.numDimensions()
      Returns:
      value of the the RandomAccessible at position.
