All Known Subinterfaces:

GridCoordinates

@UML(identifier="CV_GridCoordinates",
     specification=ISO_19123)
public interface GridCoordinates

Holds the set of grid coordinates that specifies the location of the grid point within the grid.

Since:

GeoAPI 2.1

Method Summary

int	getCoordinateValue(int dimension) Returns the coordinate value at the specified dimension.
int[]	getCoordinateValues() Returns one integer value for each dimension of the grid.
int	getDimension() Returns the number of dimensions.
void	setCoordinateValue(int dimension, int value) Sets the coordinate value at the specified dimension (optional operation).

Method Detail

getDimension

int getDimension()

Returns the number of dimensions. This method is equivalent to getCoordinateValues().length. It is provided for efficiency.

Returns:

The number of dimensions.

getCoordinateValues

@UML(identifier="coordValues",
     obligation=MANDATORY,
     specification=ISO_19123)
int[] getCoordinateValues()

Returns one integer value for each dimension of the grid. The ordering of these coordinate values shall be the same as that of the elements of Grid.getAxisNames(). The value of a single coordinate shall be the number of offsets from the origin of the grid in the direction of a specific axis.

Returns:

A copy of the coordinates. Changes in the returned array will not be reflected back in this GridCoordinates object.

getCoordinateValue

int getCoordinateValue(int dimension)
                       throws IndexOutOfBoundsException

Returns the coordinate value at the specified dimension. This method is equivalent to getCoordinateValues()[i]. It is provided for efficiency.

Parameters:

dimension - The dimension for which to obtain the coordinate value.

Returns:

The coordinate value at the given dimension.

Throws:

IndexOutOfBoundsException - If the given index is negative or is equals or greater than the grid dimension.

setCoordinateValue

void setCoordinateValue(int dimension,
                        int value)
                        throws IndexOutOfBoundsException,
                               UnsupportedOperationException

Sets the coordinate value at the specified dimension (optional operation).

Parameters:

dimension - The dimension for which to set the coordinate value.

value - The new value.

Throws:

IndexOutOfBoundsException - If the given index is negative or is equals or greater than the grid dimension.

UnsupportedOperationException - if this grid coordinates is not modifiable.
