  • Method Details

    • hasCrc32C

      boolean hasCrc32C()
       CRC32C digest of the object data. Computed by the Cloud Storage service for
 all written objects.
 If set in a WriteObjectRequest, service will validate that the stored
 object matches this checksum.
      optional fixed32 crc32c = 1;
      Returns:
      Whether the crc32c field is set.

    • getCrc32C

      int getCrc32C()
       CRC32C digest of the object data. Computed by the Cloud Storage service for
 all written objects.
 If set in a WriteObjectRequest, service will validate that the stored
 object matches this checksum.
      optional fixed32 crc32c = 1;
      Returns:
      The crc32c.

    • getMd5Hash

      com.google.protobuf.ByteString getMd5Hash()
       128 bit MD5 hash of the object data.
 For more information about using the MD5 hash, see
 [https://cloud.google.com/storage/docs/hashes-etags#json-api][Hashes and
 ETags: Best Practices].
 Not all objects will provide an MD5 hash. For example, composite objects
 provide only crc32c hashes. This value is equivalent to running `cat
 object.txt | openssl md5 -binary`
      bytes md5_hash = 2;
      Returns:
      The md5Hash.
