  • Method Details

    • hasSelect

      boolean hasSelect()
       Optional sub-set of the fields to return.

 This acts as a [DocumentMask][google.firestore.v1.DocumentMask] over the
 documents returned from a query. When not set, assumes that the caller
 wants all fields returned.
      .google.firestore.v1.StructuredQuery.Projection select = 1;
      Returns:
      Whether the select field is set.

    • getSelect

      StructuredQuery.Projection getSelect()
       Optional sub-set of the fields to return.

    • hasWhere

      boolean hasWhere()
       The filter to apply.
      .google.firestore.v1.StructuredQuery.Filter where = 3;
      Returns:
      Whether the where field is set.

      StructuredQuery.Filter getWhere()
       The filter to apply.
      .google.firestore.v1.StructuredQuery.Filter where = 3;
      Returns:

    • getWhereOrBuilder

      StructuredQuery.FilterOrBuilder getWhereOrBuilder()
       The filter to apply.
      .google.firestore.v1.StructuredQuery.Filter where = 3;

    • getOrderByList

      List<StructuredQuery.Order> getOrderByList()
       The order to apply to the query results.

 Firestore allows callers to provide a full ordering, a partial ordering, or
 no ordering at all. In all cases, Firestore guarantees a stable ordering
 through the following rules:

  * The `order_by` is required to reference all fields used with an
    inequality filter.
  * All fields that are required to be in the `order_by` but are not already
    present are appended in lexicographical ordering of the field name.
  * If an order on `__name__` is not specified, it is appended by default.

 Fields are appended with the same sort direction as the last order
 specified, or 'ASCENDING' if no order was specified. For example:

  * `ORDER BY a` becomes `ORDER BY a ASC, __name__ ASC`
  * `ORDER BY a DESC` becomes `ORDER BY a DESC, __name__ DESC`
  * `WHERE a > 1` becomes `WHERE a > 1 ORDER BY a ASC, __name__ ASC`
  * `WHERE __name__ > ... AND a > 1` becomes
     `WHERE __name__ > ... AND a > 1 ORDER BY a ASC, __name__ ASC`
      repeated .google.firestore.v1.StructuredQuery.Order order_by = 4;

    • getOrderBy

    • hasStartAt

      boolean hasStartAt()
       A potential prefix of a position in the result set to start the query at.

 The ordering of the result set is based on the `ORDER BY` clause of the
 original query.

 ```
 SELECT * FROM k WHERE a = 1 AND b > 2 ORDER BY b ASC, __name__ ASC;
 ```

 This query's results are ordered by `(b ASC, __name__ ASC)`.

 Cursors can reference either the full ordering or a prefix of the location,
 though it cannot reference more fields than what are in the provided
 `ORDER BY`.

 Continuing off the example above, attaching the following start cursors
 will have varying impact:

 - `START BEFORE (2, /k/123)`: start the query right before `a = 1 AND
    b > 2 AND __name__ > /k/123`.
 - `START AFTER (10)`: start the query right after `a = 1 AND b > 10`.

 Unlike `OFFSET` which requires scanning over the first N results to skip,
 a start cursor allows the query to begin at a logical position. This
 position is not required to match an actual result, it will scan forward
 from this position to find the next document.

 Requires:

 * The number of values cannot be greater than the number of fields
   specified in the `ORDER BY` clause.
      .google.firestore.v1.Cursor start_at = 7;
      Returns:
      Whether the startAt field is set.

    • getStartAt

      Cursor getStartAt()
       A potential prefix of a position in the result set to start the query at.

 The ordering of the result set is based on the `ORDER BY` clause of the
 original query.

 ```
 SELECT * FROM k WHERE a = 1 AND b > 2 ORDER BY b ASC, __name__ ASC;
 ```

 This query's results are ordered by `(b ASC, __name__ ASC)`.

    • hasEndAt

      boolean hasEndAt()
       A potential prefix of a position in the result set to end the query at.

 This is similar to `START_AT` but with it controlling the end position
 rather than the start position.

 Requires:

 * The number of values cannot be greater than the number of fields
   specified in the `ORDER BY` clause.
      .google.firestore.v1.Cursor end_at = 8;
      Returns:
      Whether the endAt field is set.

    • getEndAt

   specified in the `ORDER BY` clause.

      Returns:
      The endAt.

    • getEndAtOrBuilder

      CursorOrBuilder getEndAtOrBuilder()
       A potential prefix of a position in the result set to end the query at.

   specified in the `ORDER BY` clause.
      .google.firestore.v1.Cursor end_at = 8;

    • getOffset

      int getOffset()
       The number of documents to skip before returning the first result.

 This applies after the constraints specified by the `WHERE`, `START AT`, &
 `END AT` but before the `LIMIT` clause.

 Requires:

 * The value must be greater than or equal to zero if specified.
      int32 offset = 6;
      Returns:
      The offset.

    • hasLimit

      boolean hasLimit()
       The maximum number of results to return.

 Applies after all other constraints.

 Requires:

 * The value must be greater than or equal to zero if specified.
