Example 7 with BlobMetaData

use of org.elasticsearch.common.blobstore.BlobMetaData in project elasticsearch by elastic.

the class FsBlobContainer method listBlobsByPrefix.

@Override

    // If we get duplicate files we should just take the last entry
    Map<String, BlobMetaData> builder = new HashMap<>();
    blobNamePrefix = blobNamePrefix == null ? "" : blobNamePrefix;
    try (DirectoryStream<Path> stream = Files.newDirectoryStream(path, blobNamePrefix + "*")) {
        for (Path file : stream) {
            final BasicFileAttributes attrs = Files.readAttributes(file, BasicFileAttributes.class);
            if (attrs.isRegularFile()) {
                builder.put(file.getFileName().toString(), new PlainBlobMetaData(file.getFileName().toString(), attrs.size()));
            }
        }
    }
    return unmodifiableMap(builder);
