Package tech.ydb.yoj.repository.ydb

Class YdbSpliterator<V>

java.lang.Object

tech.ydb.yoj.repository.ydb.YdbSpliterator<V>

All Implemented Interfaces:

Spliterator<V>

public class YdbSpliterator<V>
extends Object
implements Spliterator<V>

YdbSpliterator is used for read data from YDB streams. It's possible to supply values from different threads, but supplier threads mustn't call onNext concurrently.

Should be closed by close() method for finish work in session.
