构造器详细资料

AbstractDataResult

public AbstractDataResult(RowList rows,
                          java.util.function.Supplier<ProtocolEntity> completer,
                          ProtocolEntityFactory<T,XMessage> rowToData)

Constructor.

参数:

rows - RowList object

completer - Supplier for StatementExecuteOk object

rowToData - ProtocolEntityFactory

方法详细资料

next

public T next()

指定者:

next 在接口中 Iterator<T>

fetchAll

public List<T> fetchAll()

Create a list of all elements in the result forcing internal buffering.

返回:

list of result elements

count

public long count()

Return the number of items in this result. Forces internal buffering of the entire result.

返回:

number of elements in result

hasNext

public boolean hasNext()

指定者:

hasNext 在接口中 Iterator<T>

getStatementExecuteOk

public StatementExecuteOk getStatementExecuteOk()

Get StatementExecuteOk object finalizing the result transfer. Forces internal buffering of the entire result.

返回:

StatementExecuteOk object

finishStreaming

public void finishStreaming()

从接口复制的说明: ResultStreamer

Finish the result streaming. This happens if a new command is started or the warnings/etc are requested. This is safe to call multiple times and only has an effect the first time.

指定者:

finishStreaming 在接口中 ResultStreamer

getAffectedItemsCount

public long getAffectedItemsCount()

从接口复制的说明: Result

Get the count of affected items from manipulation statements. This method forces internal buffering of the result.

指定者:

getAffectedItemsCount 在接口中 Result

返回:

count

getWarningsCount

public int getWarningsCount()

从接口复制的说明: Result

Get the number of warnings generated during statement execution. This method forces internal buffering of the result.

指定者:

getWarningsCount 在接口中 Result

返回:

number of warnings

getWarnings

public Iterator<Warning> getWarnings()

从接口复制的说明: Result

Get warnings generated during statement execution. This method forces internal buffering of the result.

指定者:

getWarnings 在接口中 Result

返回:

iterator over warnings
