20 * Wraps information associated with any NFC event.

22 * <p>Immutable object, with direct access to the (final) fields.
23 *
24 * <p>An {@link NfcEvent} object is usually included in callbacks from
25 * {@link NfcAdapter}. Check the documentation of the callback to see
26 * which fields may be set.
27 *
28 * <p>This wrapper object is used (instead of parameters
29 * in the callback) because it allows new fields to be added without breaking
30 * API compatibility.
