Implements

MessageOrBuilder

Methods

getEndAt()

public abstract Cursor getEndAt()

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

Type	Description
Cursor	The endAt.

getEndAtOrBuilder()

public abstract CursorOrBuilder getEndAtOrBuilder()

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

Type	Description
CursorOrBuilder

getFrom(int index)

public abstract StructuredQuery.CollectionSelector getFrom(int index)

The collections to query.

repeated .google.firestore.v1.StructuredQuery.CollectionSelector from = 2;

Parameter

Name	Description
index	int

Returns

Type	Description
StructuredQuery.CollectionSelector

getFromCount()

public abstract int getFromCount()

The collections to query.

repeated .google.firestore.v1.StructuredQuery.CollectionSelector from = 2;

Returns

Type	Description
int

getFromList()

public abstract List<StructuredQuery.CollectionSelector> getFromList()

The collections to query.

repeated .google.firestore.v1.StructuredQuery.CollectionSelector from = 2;

Returns

Type	Description
List<CollectionSelector>

getFromOrBuilder(int index)

public abstract StructuredQuery.CollectionSelectorOrBuilder getFromOrBuilder(int index)

The collections to query.

repeated .google.firestore.v1.StructuredQuery.CollectionSelector from = 2;

Parameter

Name	Description
index	int

Returns

Type	Description
StructuredQuery.CollectionSelectorOrBuilder

getFromOrBuilderList()

public abstract List<? extends StructuredQuery.CollectionSelectorOrBuilder> getFromOrBuilderList()

The collections to query.

repeated .google.firestore.v1.StructuredQuery.CollectionSelector from = 2;

Returns

Type	Description
List<? extends com.google.firestore.v1.StructuredQuery.CollectionSelectorOrBuilder>

getLimit()

public abstract Int32Value getLimit()

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.

.google.protobuf.Int32Value limit = 5;

Returns

Type	Description
Int32Value	The limit.

getLimitOrBuilder()

public abstract Int32ValueOrBuilder getLimitOrBuilder()

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.

.google.protobuf.Int32Value limit = 5;

Returns

Type	Description
Int32ValueOrBuilder

getOffset()

public abstract 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

Type	Description
int	The offset.

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

repeated .google.firestore.v1.StructuredQuery.Order order_by = 4;

Parameter

Name	Description
index	int

Returns

Type	Description
StructuredQuery.Order

getOrderByCount()

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()
