Namespace

Methods

__construct

Constructor.

Parameters
Name Description
data array

Optional. Data for populating the Message object.
↳ parent string

Required. The parent resource name. In the format: projects/{project_id}/databases/{database_id}/documents. Document resource names are not supported; only database resource names can be specified.
↳ structured_query StructuredQuery

A structured query. Query must specify collection with all descendants and be ordered by name ascending. Other filters, order bys, limits, offsets, and start/end cursors are not supported.
↳ partition_count int|string

The desired maximum number of partition points. The partitions may be returned across multiple pages of results. The number must be positive. The actual number of partitions returned may be fewer. For example, this may be set to one fewer than the number of parallel queries to be run, or in running a data pipeline job, one fewer than the number of workers or compute instances available.
↳ page_token string

The next_page_token value returned from a previous call to PartitionQuery that may be used to get an additional set of results. There are no ordering guarantees between sets of results. Thus, using multiple sets of results will require merging the different result sets. For example, two subsequent calls using a page_token may return: * * cursor B, cursor M, cursor Q * * cursor A, cursor U, cursor W To obtain a complete result set ordered with respect to the results of the query supplied to PartitionQuery, the results sets should be merged: cursor A, cursor B, cursor M, cursor Q, cursor U, cursor W
↳ page_size int

The maximum number of partitions to return in this call, subject to partition_count. For example, if partition_count = 10 and page_size = 8, the first call to PartitionQuery will return up to 8 partitions and a next_page_token if more results exist. A second call to PartitionQuery will return up to 2 partitions, to complete the total of 10 specified in partition_count.
↳ read_time Google\Protobuf\Timestamp

Reads documents as they were at the given time. This must be a microsecond precision timestamp within the past one hour, or if Point-in-Time Recovery is enabled, can additionally be a whole minute timestamp within the past 7 days.

getParent

Required. The parent resource name. In the format: projects/{project_id}/databases/{database_id}/documents.

Document resource names are not supported; only database resource names can be specified.

Returns
Type Description
string

setParent

Required. The parent resource name. In the format: projects/{project_id}/databases/{database_id}/documents.

Document resource names are not supported; only database resource names can be specified.

getStructuredQuery

A structured query.

Query must specify collection with all descendants and be ordered by name ascending. Other filters, order bys, limits, offsets, and start/end cursors are not supported.

Returns
Type Description
StructuredQuery|null

hasStructuredQuery

setStructuredQuery

A structured query.

Query must specify collection with all descendants and be ordered by name ascending. Other filters, order bys, limits, offsets, and start/end cursors are not supported.

Parameter
Name Description
var StructuredQuery
Returns
Type Description
$this

getPartitionCount

The desired maximum number of partition points.

The partitions may be returned across multiple pages of results. The number must be positive. The actual number of partitions returned may be fewer. For example, this may be set to one fewer than the number of parallel queries to be run, or in running a data pipeline job, one fewer than the number of workers or compute instances available.

Returns
Type Description
int|string

setPartitionCount

The desired maximum number of partition points.

The partitions may be returned across multiple pages of results. The number must be positive. The actual number of partitions returned may be fewer. For example, this may be set to one fewer than the number of parallel queries to be run, or in running a data pipeline job, one fewer than the number of workers or compute instances available.

Parameter
Name Description
var int|string
Returns
Type Description
$this

getPageToken

The next_page_token value returned from a previous call to PartitionQuery that may be used to get an additional set of results.

There are no ordering guarantees between sets of results. Thus, using multiple sets of results will require merging the different result sets. For example, two subsequent calls using a page_token may return:

  • cursor B, cursor M, cursor Q
  • cursor A, cursor U, cursor W To obtain a complete result set ordered with respect to the results of the query supplied to PartitionQuery, the results sets should be merged: cursor A, cursor B, cursor M, cursor Q, cursor U, cursor W
Returns
Type Description
string

setPageToken

The next_page_token value returned from a previous call to PartitionQuery that may be used to get an additional set of results.

For example, if partition_count = 10 and page_size = 8, the first call to PartitionQuery will return up to 8 partitions and a next_page_token if more results exist. A second call to PartitionQuery will return up to 2 partitions, to complete the total of 10 specified in partition_count.

Returns
Type Description
int

setPageSize
