Example 1 with NilObject

use of org.apache.sis.xml.NilObject in project sis by apache.

the class DefaultExtent method intersect.

/**
 * Sets this extent to the intersection of this extent with the specified one.

 * with all geographic, vertical and temporal elements in the other extent, ignoring duplicated results.
 *
 * @param  other  the extent to intersect with this extent.
 * @throws IllegalArgumentException if two elements to intersect are not compatible (e.g. mismatched
 *         {@linkplain DefaultGeographicBoundingBox#getInclusion() bounding box inclusion status} or
 *         mismatched {@linkplain DefaultVerticalExtent#getVerticalCRS() vertical datum}).
 * @throws UnsupportedOperationException if a {@code TemporalFactory} is required but no implementation
 *         has been found on the classpath.

 * @see Extents#intersection(Extent, Extent)
