public interface CoordSequence
extends Splittable<CoordSequence>, Sequence

Interface for iterating over coordinates. At each step, an N-dimensional coordinate array is available. This sequence is splittable, so suitable in priniciple for parallel processing.

Method Detail

getCoords

double[] getCoords()

Returns the array used to store the coordinates for the current position in this sequence. It contains the coordinates corresponding to the last call of the next() method. Its contents before the first call or after a call returning false are undefined.

This method returns the same value throughout the lifetime of this sequence, it's only the contents that change to reflect the current state of the iteration.

next

boolean next()

Advances to the next entry. No exception is thrown.

Specified by:

next in interface Sequence

Returns:

true iff the current sequence element has data
