      • values

        public static Type[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (Type c : Type.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static Type valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null

      • getRawTableName

        public java.lang.String getRawTableName​(Priority priority)

        priority - the priority of the table
        Returns:
        the table name

      • getAggregate5mTableName

        public java.lang.String getAggregate5mTableName​(Priority priority)
        Gets the aggregate table name of the current type and the specified priority.
        Parameters:
        priority - the priority of the table
        Returns:
        the table name

      • fillRow

        public java.util.function.Consumer<de.bytefish.pgbulkinsert.row.SimpleRow> fillRow​(Point point)
        Fills a PgBulkInsert Row-Writer with data (timestamp, channel_id and value).
        Parameters:
        point - the Point holding data
        Returns:
        a Consumer as required by SimpleRowWriter.startRow(Consumer)
        Throws:
        java.lang.Exception - on error
