/**
 * This class defines a log field syntax for values that are JSON objects.  This
 * syntax allows individual field values to be redacted or tokenized within the
 * JSON objects.  If a JSON object is completely redacted, then the redacted
 * representation will be { "redacted":"{REDACTED}" }.  If a JSON
 * object is completely tokenized, then the tokenized representation will be
 * { "tokenized":"{TOKENIZED:token-value}" }", where token-value
 * will be replaced with a generated value.
 * 
*
* NOTE: This class, and other classes within the * {@code com.unboundid.ldap.sdk.unboundidds} package structure, are only * supported for use against Ping Identity, UnboundID, and * Nokia/Alcatel-Lucent 8661 server products. These classes provide support * for proprietary functionality or for external specifications that are not * considered stable or mature enough to be guaranteed to work in an * interoperable way with other types of LDAP servers. *
