Example 67 with Duration

use of javax.xml.datatype.Duration in project structure-project by wudskq.

the class DurationImpl method add.

/**
 * <p>Computes a new duration whose value is <code>this+rhs</code>.</p>
 *
 * <p>For example,</p>
 * <pre>
 * "1 day" + "-3 days" = "-2 days"
 * "1 year" + "1 day" = "1 year and 1 day"
 * "-(1 hour,50 minutes)" + "-20 minutes" = "-(1 hours,70 minutes)"
 * "15 hours" + "-3 days" = "-(2 days,9 hours)"
 * "1 year" + "-1 day" = IllegalStateException
 * </pre>
 *
 * <p>Since there's no way to meaningfully subtract 1 day from 1 month,
 * there are cases where the operation fails in
 * {@link IllegalStateException}.</p>
 *
 * <p>
 * Formally, the computation is defined as follows.</p>
 * <p>
 * Firstly, we can assume that two {@link Duration}s to be added
 * are both positive without losing generality (i.e.,
 * <code>(-X)+Y=Y-X</code>, <code>X+(-Y)=X-Y</code>,
 * <code>(-X)+(-Y)=-(X+Y)</code>)
 *
 * <p>
 * Addition of two positive {@link Duration}s are simply defined as
 * field by field addition where missing fields are treated as 0.
 * <p>
 * A field of the resulting {@link Duration} will be unset if and
 * only if respective fields of two input {@link Duration}s are unset.
 * <p>
 * Note that <code>lhs.add(rhs)</code> will be always successful if
 * <code>lhs.signum()*rhs.signum()!=-1</code> or both of them are
 * normalized.</p>
 *
 * @param rhs <code>Duration</code> to add to this <code>Duration</code>
 *
 * @return
 *      non-null valid Duration object.
 *
 * @throws NullPointerException
 *      If the rhs parameter is null.
 * @throws IllegalStateException
 *      If two durations cannot be meaningfully added. For
 *      example, adding negative one day to one month causes
 *      this exception.
 *
 * @see #subtract(Duration)
