static void |
copy(CoordinateSequence src,
int srcPos,
CoordinateSequence dest,
int destPos,
int length)
Copies a section of a
CoordinateSequence to another CoordinateSequence . |
static void |
copyCoord(CoordinateSequence src,
int srcPos,
CoordinateSequence dest,
int destPos)
Copies a coordinate of a
CoordinateSequence to another CoordinateSequence . |
static CoordinateSequence |
ensureValidRing(CoordinateSequenceFactory fact,
CoordinateSequence seq)
Ensures that a CoordinateSequence forms a valid ring,
returning a new closed sequence of the correct length if required.
|
static CoordinateSequence |
extend(CoordinateSequenceFactory fact,
CoordinateSequence seq,
int size) |
static boolean |
isRing(CoordinateSequence seq)
Tests whether a
CoordinateSequence forms a valid LinearRing ,
by checking the sequence length and closure
(whether the first and last points are identical in 2D). |
static void |
reverse(CoordinateSequence seq)
Reverses the coordinates in a sequence in-place.
|
static void |
swap(CoordinateSequence seq,
int i,
int j)
Swaps two coordinates in a sequence.
