Example 1 with SegmentInfo

use of io.pravega.client.segment.impl.SegmentInfo in project pravega by pravega.

the class RevisionedStreamClientImpl method readFrom.

@Override

        log.trace("Creating iterator from {} until {}", startOffset, endOffset);
        return new StreamIterator(startOffset, endOffset);
    }
}

Example 2 with SegmentInfo

use of io.pravega.client.segment.impl.SegmentInfo in project pravega by pravega.

the class BatchClientImpl method getSegmentRange.

/*
     * Given a segment, fetch its SegmentRange.
     * - If segment is part of startStreamCut / endStreamCut update startOffset and endOffset accordingly.
     * - If segment is not part of the streamCuts fetch the data using SegmentMetadataClient.
