Methods

getEndAt()

public abstract Cursor getEndAt()

.google.firestore.v1.Cursor end_at = 8;

Returns
Type Description
Cursor

The endAt.

getEndAtOrBuilder()

public abstract CursorOrBuilder getEndAtOrBuilder()

getOrderBy(int index)

public abstract StructuredQuery.Order getOrderBy(int index)

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

Name Description
index int
Returns

getSelect()

public abstract StructuredQuery.Projection getSelect()

getStartAt()

public abstract 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).

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
    Type Description
    Cursor

    The startAt.

    getStartAtOrBuilder()
