Returns:

The table.

getTableBytes

ByteString getTableBytes()

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

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

Returns:

The bytes for table.

getIndex

String getIndex()

 If non-empty, the name of an index on [table][google.spanner.v1.ReadRequest.table]. This index is
 used instead of the table primary key when interpreting [key_set][google.spanner.v1.ReadRequest.key_set]
 and sorting result rows. See [key_set][google.spanner.v1.ReadRequest.key_set] for further information.
 

string index = 4;

Returns:

The index.

getIndexBytes

ByteString getIndexBytes()

 If non-empty, the name of an index on [table][google.spanner.v1.ReadRequest.table]. This index is
 used instead of the table primary key when interpreting [key_set][google.spanner.v1.ReadRequest.key_set]
 and sorting result rows. See [key_set][google.spanner.v1.ReadRequest.key_set] for further information.
 

string index = 4;

Returns:

The bytes for index.

getColumnsList

List<String> getColumnsList()

 Required. The columns of [table][google.spanner.v1.ReadRequest.table] to be returned for each row matching
 this request.
 

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

Returns:

A list containing the columns.

getColumnsCount

int getColumnsCount()

 Required. The columns of [table][google.spanner.v1.ReadRequest.table] to be returned for each row matching
 this request.
 

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

Returns:

The count of columns.

getColumns

String getColumns(int index)

 Required. The columns of [table][google.spanner.v1.ReadRequest.table] to be returned for each row matching
 this request.
 

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

Parameters:

index - The index of the element to return.

Returns:

The columns at the given index.

getColumnsBytes

ByteString getColumnsBytes(int index)

 Required. The columns of [table][google.spanner.v1.ReadRequest.table] to be returned for each row matching
 this request.
 

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

Parameters:

index - The index of the value to return.

Returns:

The bytes of the columns at the given index.

hasKeySet

boolean hasKeySet()

 Required. `key_set` identifies the rows to be yielded. `key_set` names the
 primary keys of the rows in [table][google.spanner.v1.ReadRequest.table] to be yielded, unless [index][google.spanner.v1.ReadRequest.index]
 is present. If [index][google.spanner.v1.ReadRequest.index] is present, then [key_set][google.spanner.v1.ReadRequest.key_set] instead names
 index keys in [index][google.spanner.v1.ReadRequest.index].
 If the [partition_token][google.spanner.v1.ReadRequest.partition_token] field is empty, rows are yielded
 in table primary key order (if [index][google.spanner.v1.ReadRequest.index] is empty) or index key order
 (if [index][google.spanner.v1.ReadRequest.index] is non-empty).  If the [partition_token][google.spanner.v1.ReadRequest.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:

Whether the keySet field is set.

getKeySet

KeySet getKeySet()

 Required. `key_set` identifies the rows to be yielded. `key_set` names the
 primary keys of the rows in [table][google.spanner.v1.ReadRequest.table] to be yielded, unless [index][google.spanner.v1.ReadRequest.index]
 is present. If [index][google.spanner.v1.ReadRequest.index] is present, then [key_set][google.spanner.v1.ReadRequest.key_set] instead names
 index keys in [index][google.spanner.v1.ReadRequest.index].
 If the [partition_token][google.spanner.v1.ReadRequest.partition_token] field is empty, rows are yielded
 in table primary key order (if [index][google.spanner.v1.ReadRequest.index] is empty) or index key order
 (if [index][google.spanner.v1.ReadRequest.index] is non-empty).  If the [partition_token][google.spanner.v1.ReadRequest.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:

The keySet.

getKeySetOrBuilder

KeySetOrBuilder getKeySetOrBuilder()

 Required. `key_set` identifies the rows to be yielded. `key_set` names the
 primary keys of the rows in [table][google.spanner.v1.ReadRequest.table] to be yielded, unless [index][google.spanner.v1.ReadRequest.index]
 is present. If [index][google.spanner.v1.ReadRequest.index] is present, then [key_set][google.spanner.v1.ReadRequest.key_set] instead names
 index keys in [index][google.spanner.v1.ReadRequest.index].
 If the [partition_token][google.spanner.v1.ReadRequest.partition_token] field is empty, rows are yielded
 in table primary key order (if [index][google.spanner.v1.ReadRequest.index] is empty) or index key order
 (if [index][google.spanner.v1.ReadRequest.index] is non-empty).  If the [partition_token][google.spanner.v1.ReadRequest.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];

getLimit

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:

The limit.

getResumeToken

ByteString getResumeToken()

 If this request is resuming a previously interrupted read,
 `resume_token` should be copied from the last
 [PartialResultSet][google.spanner.v1.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:

The resumeToken.

getPartitionToken

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:

The partitionToken.

hasRequestOptions

boolean hasRequestOptions()

 Common options for this request.
 

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

Returns:

Whether the requestOptions field is set.

getRequestOptions

RequestOptions getRequestOptions()

 Common options for this request.
 

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

Returns:

The requestOptions.

getRequestOptionsOrBuilder

RequestOptionsOrBuilder getRequestOptionsOrBuilder()

 Common options for this request.
 

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