Interface GridEnvelope

  • All Known Implementing Classes:
    GeneralGridEnvelope, GridEnvelope2D
    @UML(identifier="CV_GridEnvelope",
     specification=ISO_19123)
public interface GridEnvelope
    Provides the grid coordinate values for the diametrically opposed corners of the grid.

    Remark that both corners are inclusive. Thus the number of elements in the direction of the first axis is getHigh(0) - getLow(0) + 1. This is the opposite of Java2D usage where maximal values in Rectangle (as computed by getMaxX() and getMaxY()) are exclusive.

    Since:
    GeoAPI 2.1

    • Method Detail

      • getDimension

        @Extension
int getDimension()
        Returns the number of dimensions. It must be equals to the number of dimensions of low and high grid coordinates.
        Returns:
        The number of dimensions.
        Since:
        GeoAPI 2.2

      • getLow

        @Extension
int getLow​(int dimension)
    throws IndexOutOfBoundsException
        Returns the valid minimum inclusive grid coordinate along the specified dimension. This is a shortcut for the following without the cost of creating a temporary GridCoordinates object:
        getLow().getCoordinateValue(dimension)
        Parameters:
        dimension - The dimension for which to obtain the coordinate value.
        Returns:
        The coordinate value at the given dimension, inclusive.
        Throws:
        IndexOutOfBoundsException - If the given index is negative or is equals or greater than the grid dimension.
        Since:
        GeoAPI 2.2

      • getHigh

        @Extension
int getHigh​(int dimension)
     throws IndexOutOfBoundsException
        Returns the valid maximum inclusive grid coordinate along the specified dimension. This is a shortcut for the following without the cost of creating a temporary GridCoordinates object:
        getHigh().getCoordinateValue(dimension)
        Parameters:
        dimension - The dimension for which to obtain the coordinate value.
        Returns:
        The coordinate value at the given dimension, inclusive.
        Throws:
        IndexOutOfBoundsException - If the given index is negative or is equals or greater than the grid dimension.
        Since:
        GeoAPI 2.2

      • getSpan

        @Extension
int getSpan​(int dimension)
     throws IndexOutOfBoundsException
        Returns the number of integer grid coordinates along the specified dimension. This is equals to:
        getHigh(dimension) - getLow(dimension) + 1
        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.
