059 * This class defines an API that must be implemented by extensions which can
060 * be used to classify client search result entries.
061 * <BR>
062 * <H2>Configuring Search Entry Criteria</H2>
063 * In order to configure a search entry criteria object created using this API,
064 * use a command like:
065 * <PRE>
066 *      dsconfig create-search-entry-criteria \
067 *           --criteria-name "<I>{criteria-name}</I>" \
068 *           --type third-party \
069 *           --set enabled:true \
070 *           --set "extension-class:<I>{class-name}</I>" \
071 *           --set "extension-argument:<I>{name=value}</I>"
072 * </PRE>
073 * where "<I>{criteria-name}</I>" is the name to use for the search entry
074 * criteria instance, "<I>{class-name}</I>" is the fully-qualified name of the
075 * Java class that extends
076 * {@code com.unboundid.directory.sdk.ds.api.SearchEntryCriteria}, and
077 * "<I>{name=value}</I>" represents name-value pairs for any arguments to
078 * provide to the search entry criteria.  If multiple arguments should be
079 * provided to the search entry criteria instance, then the
080 * "<CODE>--set extension-argument:<I>{name=value}</I></CODE>" option should be
081 * provided multiple times.
