    • Method Detail

      • checksumCRC32

        public final String checksumCRC32()

        The Base64 encoded, 32-bit CRC32 checksum of the object. This checksum is only be present if the checksum was uploaded with the object. When you use an API operation on an object that was uploaded using multipart uploads, this value may not be a direct checksum value of the full object. Instead, it's a calculation based on the checksum values of each individual part. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.

        Returns:
        The Base64 encoded, 32-bit CRC32 checksum of the object. This checksum is only be present if the checksum was uploaded with the object. When you use an API operation on an object that was uploaded using multipart uploads, this value may not be a direct checksum value of the full object. Instead, it's a calculation based on the checksum values of each individual part. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.

      • checksumCRC32C

        public final String checksumCRC32C()

        The Base64 encoded, 32-bit CRC32C checksum of the object. This checksum is only present if the checksum was uploaded with the object. When you use an API operation on an object that was uploaded using multipart uploads, this value may not be a direct checksum value of the full object. Instead, it's a calculation based on the checksum values of each individual part. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.

        Returns:
        The Base64 encoded, 32-bit CRC32C checksum of the object. This checksum is only present if the checksum was uploaded with the object. When you use an API operation on an object that was uploaded using multipart uploads, this value may not be a direct checksum value of the full object.

      • checksumCRC64NVME

        public final String checksumCRC64NVME()

        The Base64 encoded, 64-bit CRC64NVME checksum of the object. This checksum is present if the object was uploaded with the CRC64NVME checksum algorithm, or if the object was uploaded without a checksum (and Amazon S3 added the default checksum, CRC64NVME, to the uploaded object). For more information, see Checking object integrity in the Amazon S3 User Guide.

        Returns:
        The Base64 encoded, 64-bit CRC64NVME checksum of the object. This checksum is present if the object was uploaded with the CRC64NVME checksum algorithm, or if the object was uploaded without a checksum (and Amazon S3 added the default checksum, CRC64NVME, to the uploaded object). For more information, see Checking object integrity in the Amazon S3 User Guide.

      • checksumSHA1

        public final String checksumSHA1()

        The Base64 encoded, 160-bit SHA1 digest of the object. This will only be present if the object was uploaded with the object. When you use the API operation on an object that was uploaded using multipart uploads, this value may not be a direct checksum value of the full object. Instead, it's a calculation based on the checksum values of each individual part. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.

        Returns:
        The Base64 encoded, 160-bit SHA1 digest of the object. This will only be present if the object was uploaded with the object.

      • checksumSHA256

        public final String checksumSHA256()

        The Base64 encoded, 256-bit SHA256 digest of the object. This will only be present if the object was uploaded with the object. When you use an API operation on an object that was uploaded using multipart uploads, this value may not be a direct checksum value of the full object. Instead, it's a calculation based on the checksum values of each individual part. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.

        Returns:
        The Base64 encoded, 256-bit SHA256 digest of the object. This will only be present if the object was uploaded with the object.

      • checksumTypeAsString

        public final String checksumTypeAsString()

        The checksum type that is used to calculate the object’s checksum value. For more information, see Checking object integrity in the Amazon S3 User Guide.

        If the service returns an enum value that is not available in the current SDK version, checksumType will return ChecksumType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from checksumTypeAsString().

        Returns:
        The checksum type that is used to calculate the object’s checksum value. For more information, see Checking object integrity in the Amazon S3 User Guide.
