Examples with DateValueNode org.xwiki.notifications.filters.expression.DateValueNode used on opensource projects

Example 1 with DateValueNode

use of org.xwiki.notifications.filters.expression.DateValueNode in project xwiki-platform by xwiki.

the class QueryGenerator method generateQueryExpression.

/**
 * Generate the query.
 *
 * @param user user interested in the notifications
 * @param format only match notifications enabled for that format
 * @param endDate do not return events happened after this date
 * @param startDate do not return events happened before this date. Note that since 9.7RC1, this start date is
 * completely optional, {@link NotificationPreference#getStartDate()} should be used for more granular control on
 * notifications
 * @param blackList list of ids of blacklisted events to not return (to not get already known events again)
 * @return the query to execute
 *
 * @throws NotificationException if error happens
 * @throws QueryException if error happens
 *
 * @since 9.8RC1
