83 * within in a program, and so it would be considered a programming error
84 * for the URI not to parse as such. The {@link net.jxta.id.IDFactory},
85 * which throws {@link java.net.URISyntaxException} directly, should be used
86 * situations where a ID is being constructed from user input or from some
87 * other source that may be prone to errors.

92 * @throws NullPointerException If {@code fromURI} is {@code null}.
93 * @throws IllegalArgumentException If the given URI is not a valid ID.
