BatchGetRowRequest

public BatchGetRowRequest()

方法详细资料

getOperationName

public String getOperationName()

指定者:

getOperationName 在接口中 Request

addMultiRowQueryCriteria

public void addMultiRowQueryCriteria(MultiRowQueryCriteria criteria)

Add multi-row query parameters for a table. If query conditions for the table have already been added, the previous query conditions will be overwritten.

参数:

criteria - Single-row query condition

getPrimaryKey

public PrimaryKey getPrimaryKey(String tableName,
                                int index)

Returns the primary key of a specific row based on the table name and index. The multi-row results returned in BatchGetRowResult allow partial success and partial failure, with results organized by table, and the order of rows within the table corresponds one-to-one with the BatchGetRowRequest. If the user needs to retry some failed GetRow queries in the BatchGetRowResult, they can look up the corresponding row's primary key from the BatchGetRowRequest using the table name and its index in the result list where the failed query resides.

参数:

tableName - The name of the table

index - The index of the row in the parameter list

返回:

The primary key of the row

getCriteriasByTable

public Map<String,MultiRowQueryCriteria> getCriteriasByTable()

Get the multi-row query parameters organized by table.

返回:

Multi-row query parameters.

getCriteria

public MultiRowQueryCriteria getCriteria(String tableName)

Get the multi-row query parameters for the specified table.

参数:

tableName - The name of the table

返回:

If the row exists, return the query parameters for that row, otherwise return null

createRequestForRetry

public BatchGetRowRequest createRequestForRetry(List<BatchGetRowResponse.RowResult> failedRows)

Creates a new request for retry based on the returned result.

参数:

failedRows - rows that failed to query in the returned result

返回:

a new request

isEmpty

public boolean isEmpty()
