throws org.opengis.referencing.operation.NoninvertibleTransformException

Creates a new datum shift grid with the given grid geometry, filename and number of shift dimensions. All double values given to this constructor will be converted from degrees to radians.

Throws:

org.opengis.referencing.operation.NoninvertibleTransformException

Double

private Double(DatumShiftGridFile<C,T> grid,
 double[][] offsets)

Creates a new grid of the same geometry than the given grid but using a different data array.

Method Details

setData

protected final DatumShiftGridFile<C,T> setData(Object[] other)

Returns a new grid with the same geometry than this grid but different data arrays. See DatumShiftGridFile.Float.setData(Object[]) for more documentation.

Specified by:

setData in class DatumShiftGridFile<C extends javax.measure.Quantity<C>, T extends javax.measure.Quantity<T>>

Parameters:

other - data from another DatumShiftGridFile that we can share.

Returns:

a new DatumShiftGridFile using the given data reference.

getData

protected final Object[] getData()

Returns direct references (not cloned) to the data arrays. See DatumShiftGridFile.Float.getData() for more documentation.

Specified by:

getData in class DatumShiftGridFile<C extends javax.measure.Quantity<C>, T extends javax.measure.Quantity<T>>

Returns:

a direct (not cloned) reference to the internal data array.

getTranslationDimensions

public final int getTranslationDimensions()

Returns the number of shift dimensions.

Specified by:

getTranslationDimensions in class DatumShiftGrid<C extends javax.measure.Quantity<C>, T extends javax.measure.Quantity<T>>

Returns:

number of dimensions of translation vectors.

getCellValue

public final double getCellValue(int dim,
 int gridX,
 int gridY)

Returns the cell value at the given dimension and grid index. See DatumShiftGridFile.Float.getCellValue(int, int, int) for more documentation.

Specified by:

getCellValue in class DatumShiftGrid<C extends javax.measure.Quantity<C>, T extends javax.measure.Quantity<T>>

Parameters:

dim - the dimension of the translation vector component to get, from 0 inclusive to DatumShiftGrid.getTranslationDimensions() exclusive.

gridX - the grid index on the x axis, from 0 inclusive to gridSize[0] exclusive.

gridY - the grid index on the y axis, from 0 inclusive to gridSize[1] exclusive.

Returns:

the translation for the given dimension in the grid cell at the given index.
