Examples with StreamSegmentMetadata io.pravega.segmentstore.server.containers.StreamSegmentMetadata used on opensource projects

Example 1 with StreamSegmentMetadata

use of io.pravega.segmentstore.server.containers.StreamSegmentMetadata in project pravega by pravega.

the class ContainerMetadataUpdateTransaction method createSegmentMetadata.

/**
 * Creates a new UpdateableSegmentMetadata for the given Segment and registers it.
 */
private UpdateableSegmentMetadata createSegmentMetadata(String segmentName, long segmentId, long parentId) {
    UpdateableSegmentMetadata metadata;
    if (parentId == ContainerMetadata.NO_STREAM_SEGMENT_ID) {
        metadata = new StreamSegmentMetadata(segmentName, segmentId, this.containerId);
    } else {
        metadata = new StreamSegmentMetadata(segmentName, segmentId, parentId, this.containerId);
    }
    this.newSegments.put(metadata.getId(), metadata);
    this.newSegmentNames.put(metadata.getName(), metadata.getId());
    return metadata;
}

Example 2 with StreamSegmentMetadata

use of io.pravega.segmentstore.server.containers.StreamSegmentMetadata in project pravega by pravega.
