Example 6 with Time

use of javax.measure.quantity.Time in project sis by apache.

the class Store method parseEnvelope.

/**
 * Parses the envelope described by the header line starting with {@code @stboundedby}.
 * The envelope returned by this method will be stored in the {@link #envelope} field.
 *
 * <p>Example:</p>
 * {@preformat text
 *   &#64;stboundedby, urn:ogc:def:crs:CRS:1.3:84, 2D, 50.23 9.23, 50.31 9.27, 2012-01-17T12:33:41Z, 2012-01-17T12:37:00Z, sec
 * }
 *
 * This method sets {@link #timeEncoding} and {@link #spatialDimensionCount} as a side-effect.
 *
 * @param  elements  the line elements. The first elements should be {@code "@stboundedby"}.
 * @return the envelope, or {@code null} if the given list does not contain enough elements.
