Methods

getColumns(int index)

public abstract String getColumns(int index)

Required. The columns of table to be returned for each row matching this request.

repeated string columns = 5 [(.google.api.field_behavior) = REQUIRED];

Parameter
Name	Description
index	int The index of the element to return.

Returns
Type	Description
String	The columns at the given index.

getColumnsBytes(int index)

public abstract ByteString getColumnsBytes(int index)

Required. The columns of table to be returned for each row matching this request.

repeated string columns = 5 [(.google.api.field_behavior) = REQUIRED];

Parameter
Name	Description
index	int The index of the value to return.

Returns
Type	Description
ByteString	The bytes of the columns at the given index.

getColumnsCount()

public abstract int getColumnsCount()

Required. The columns of table to be returned for each row matching this request.

repeated string columns = 5 [(.google.api.field_behavior) = REQUIRED];

Returns
Type	Description
int	The count of columns.

getColumnsList()

public abstract List<String> getColumnsList()

Required. The columns of table to be returned for each row matching this request.

repeated string columns = 5 [(.google.api.field_behavior) = REQUIRED];

Returns
Type	Description
List<String>	A list containing the columns.

getDataBoostEnabled()

public abstract boolean getDataBoostEnabled()

If this is for a partitioned read and this field is set to true, the request is executed with Spanner Data Boost independent compute resources.

If the field is set to true but the request does not set partition_token, the API returns an INVALID_ARGUMENT error.

bool data_boost_enabled = 15;

Returns
Type	Description
boolean	The dataBoostEnabled.

getDirectedReadOptions()

public abstract DirectedReadOptions getDirectedReadOptions()

Directed read options for this request.

.google.spanner.v1.DirectedReadOptions directed_read_options = 14;

Returns
Type	Description
DirectedReadOptions	The directedReadOptions.

getDirectedReadOptionsOrBuilder()

public abstract DirectedReadOptionsOrBuilder getDirectedReadOptionsOrBuilder()

Directed read options for this request.

.google.spanner.v1.DirectedReadOptions directed_read_options = 14;

Returns
Type	Description
DirectedReadOptionsOrBuilder

getIndex()

public abstract String getIndex()

If non-empty, the name of an index on table. This index is used instead of the table primary key when interpreting key_set and sorting result rows. See key_set for further information.

string index = 4;

Returns
Type	Description
String	The index.

getIndexBytes()

public abstract ByteString getIndexBytes()

If non-empty, the name of an index on table. This index is used instead of the table primary key when interpreting key_set and sorting result rows. See key_set for further information.

string index = 4;

Returns
Type	Description
ByteString	The bytes for index.

getKeySet()

public abstract KeySet getKeySet()

Required. key_set identifies the rows to be yielded. key_set names the primary keys of the rows in table to be yielded, unless index is present. If index is present, then key_set instead names index keys in index.

If the partition_token field is empty, rows are yielded in table primary key order (if index is empty) or index key order (if index is non-empty). If the partition_token field is not empty, rows will be yielded in an unspecified order.

It is not an error for the key_set to name rows that do not exist in the database. Read yields nothing for nonexistent rows.

.google.spanner.v1.KeySet key_set = 6 [(.google.api.field_behavior) = REQUIRED];

Returns
Type	Description
KeySet	The keySet.

getKeySetOrBuilder()

public abstract KeySetOrBuilder getKeySetOrBuilder()

Required. key_set identifies the rows to be yielded. key_set names the primary keys of the rows in table to be yielded, unless index is present. If index is present, then key_set instead names index keys in index.

If the partition_token field is empty, rows are yielded in table primary key order (if index is empty) or index key order (if index is non-empty). If the partition_token field is not empty, rows will be yielded in an unspecified order.

It is not an error for the key_set to name rows that do not exist in the database. Read yields nothing for nonexistent rows.

.google.spanner.v1.KeySet key_set = 6 [(.google.api.field_behavior) = REQUIRED];

Returns
Type	Description
KeySetOrBuilder

getLimit()

public abstract long getLimit()

If greater than zero, only the first limit rows are yielded. If limit is zero, the default is no limit. A limit cannot be specified if partition_token is set.

int64 limit = 8;

Returns
Type	Description
long	The limit.

getPartitionToken()

public abstract ByteString getPartitionToken()

If present, results will be restricted to the specified partition previously created using PartitionRead(). There must be an exact match for the values of fields common to this message and the PartitionReadRequest message used to create this partition_token.

bytes partition_token = 10;

Returns
Type	Description
ByteString	The partitionToken.

getRequestOptions()

public abstract RequestOptions getRequestOptions()

Common options for this request.

.google.spanner.v1.RequestOptions request_options = 11;

Returns
Type	Description
RequestOptions	The requestOptions.

getRequestOptionsOrBuilder()

public abstract RequestOptionsOrBuilder getRequestOptionsOrBuilder()

Common options for this request.

.google.spanner.v1.RequestOptions request_options = 11;

Returns
Type	Description
RequestOptionsOrBuilder

getResumeToken()

public abstract ByteString getResumeToken()

If this request is resuming a previously interrupted read, resume_token should be copied from the last PartialResultSet yielded before the interruption. Doing this enables the new read to resume where the last read left off. The rest of the request parameters must exactly match the request that yielded this token.

bytes resume_token = 9;

Returns
Type	Description
ByteString	The resumeToken.

getSession()

public abstract String getSession()

Required. The session in which the read should be performed.

string session = 1 [(.google.api.field_behavior) = REQUIRED, (.google.api.resource_reference) = { ... }

Returns
Type	Description
String	The session.

getSessionBytes()

public abstract ByteString getSessionBytes()

Required. The session in which the read should be performed.

string session = 1 [(.google.api.field_behavior) = REQUIRED, (.google.api.resource_reference) = { ... }

Returns
Type	Description
ByteString	The bytes for session.

getTable()

public abstract String getTable()

Required. The name of the table in the database to be read.

string table = 3 [(.google.api.field_behavior) = REQUIRED];

Returns
Type	Description
String	The table.

getTableBytes()

public abstract ByteString getTableBytes()

Required. The name of the table in the database to be read.

string table = 3 [(.google.api.field_behavior) = REQUIRED];

Returns
Type	Description
ByteString	The bytes for table.

getTransaction()

public abstract TransactionSelector getTransaction()

The transaction to use. If none is provided, the default is a temporary read-only transaction with strong concurrency.

.google.spanner.v1.TransactionSelector transaction = 2;

Returns
Type	Description

getTransactionOrBuilder()

public abstract TransactionSelectorOrBuilder getTransactionOrBuilder()

hasDirectedReadOptions()

public abstract boolean hasDirectedReadOptions()

Directed read options for this request.

.google.spanner.v1.DirectedReadOptions directed_read_options = 14;

Returns
Type	Description
boolean	Whether the directedReadOptions field is set.

hasKeySet()

public abstract boolean hasKeySet()

Required. key_set identifies the rows to be yielded. key_set names the primary keys of the rows in table to be yielded, unless index is present. If index is present, then key_set instead names index keys in index.

If the partition_token field is empty, rows are yielded in table primary key order (if index is empty) or index key order (if index is non-empty). If the partition_token field is not empty, rows will be yielded in an unspecified order.

It is not an error for the key_set to name rows that do not exist in the database. Read yields nothing for nonexistent rows.
