Method Detail
-
getCoords
Coord[] getCoords()
Returns the coordinate definitions.- Returns:
- coords
-
getPointCount
int getPointCount()
Returns the number of (non-central) data positions defined by this coord set.- Returns:
- data position count
-
readPoints
boolean readPoints(Tuple tuple, int icol, DataGeom geom, double[] dpos0, double[][] dposExtras)
Reads the non-central points from a appropriate span of columns in a supplied tuple. The central data position must be supplied as input. Theicol
value gives the column corresponding to the first coord of this coordinate set in the sequence; the following few columns are assumed to correspod 1:1 to the coords in this coord set.- Parameters:
tuple
- tupleicol
- index of tuple field corresponding to the first of the coordinates in this setgeom
- converter between tuple values and data space coordinates; may not be requireddpos0
- nDataDim-element array giving central data positiondposExtras
- [nPointCount][nDataDim]-shaped array into which the non-central data positions will be written- Returns:
- true iff the conversion was successful
