Example 1 with SegmentIdProvider

use of org.apache.jackrabbit.oak.segment.SegmentIdProvider in project jackrabbit-oak by apache.

the class StandbyTestUtils method mockSegment.

public static Segment mockSegment(UUID uuid, byte[] buffer) {
    SegmentStore store = mock(SegmentStore.class);
    SegmentIdProvider idProvider = mock(SegmentIdProvider.class);
    SegmentReader reader = mock(SegmentReader.class);
    long msb = uuid.getMostSignificantBits();
    long lsb = uuid.getLeastSignificantBits();
    SegmentId id = new SegmentId(store, msb, lsb);
    ByteBuffer data = ByteBuffer.wrap(buffer);
    return new Segment(idProvider, reader, id, data);
}
