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

Constructor.

Parameters
rows:RowList

RowList object

completer:Supplier<ProtocolEntity>

Supplier for StatementExecuteOk object

rowToData:ProtocolEntityFactory<T, XMessage>

ProtocolEntityFactory

Method Detail

countback to summary
public long count()

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

Returns:long

number of elements in result

fetchAllback to summary
public List<T> fetchAll()

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

Returns:List<T>

list of result elements

finishStreamingback to summary
public void finishStreaming()

Implements com.mysql.cj.protocol.ResultStreamer.finishStreaming.

Doc from com.mysql.cj.protocol.ResultStreamer.finishStreaming.

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.

@Override
hasNextback to summary
public boolean hasNext()

Implements java.util.Iterator.hasNext.

Doc from java.util.Iterator.hasNext.

Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)

Returns:boolean

true if the iteration has more elements
