 * Example:
 *<pre>
 * // to prevent specified fields from being serialized or deserialized
 * // (i.e. not include in JSON output; or being set even if they were included)
 * \@JsonIgnoreProperties({ "internalId", "secretKey" })
 * // To ignore any unknown properties in JSON input without exception:
 * \@JsonIgnoreProperties(ignoreUnknown=true)
 *</pre>
 *<p>
 * Only applicable to classes, not for properties (getters, setters, fields).
