      • evaluateExpressionsAndExecuteCount

        public long evaluateExpressionsAndExecuteCount​(CommandContext commandContext)

      • executeCount

        public abstract long executeCount​(CommandContext commandContext)

      • evaluateExpressionsAndExecuteList

        public java.util.List<U> evaluateExpressionsAndExecuteList​(CommandContext commandContext,
                                                           Page page)

      • hasExcludingConditions

        protected boolean hasExcludingConditions()
        Whether or not the query has excluding conditions. If the query has excluding conditions, (e.g. task due date before and after are excluding), the SQL query is avoided and a default result is returned. The returned result is the same as if the SQL was executed and there were no entries.
        Returns:
        true if the query does have excluding conditions, false otherwise

        Executes the actual query to retrieve the list of results.
        Parameters:
        page - used if the results must be paged. If null, no paging will be applied.
