        public int readBlob​(java.lang.String blobId,
                    long pos,
                    byte[] buff,
                    int off,
                    int length)
             throws java.io.IOException
        Description copied from interface: BlobStore
        Read a number of bytes from a blob.
        Specified by:
        readBlob in interface BlobStore
        Parameters:
        blobId - the blob id
        pos - the position within the blob
        buff - the target byte array
        off - the offset within the target array
        length - the number of bytes to read
        Returns:
        the number of bytes read
        Throws:

      • getBlobLength

        public long getBlobLength​(java.lang.String blobId)
                   throws java.io.IOException
        Description copied from interface: BlobStore
        Get the length of the blob.
        Specified by:
        getBlobLength in interface BlobStore
        Parameters:

      • getInputStream

        public java.io.InputStream getInputStream​(java.lang.String blobId)
                                   throws java.io.IOException
        Description copied from interface: BlobStore
        Returns a new stream for given blobId. The streams returned from multiple calls to this method are byte wise equals. That is, subsequent calls to read return the same sequence of bytes as long as neither call throws an exception.
        Specified by:

        Description copied from interface: BlobStore
        Returns the blobId that referred by the given binary reference. Returns null if the reference is invalid, for example if it points to a blob that does not exist.
        Specified by:
        getBlobId in interface BlobStore
        Parameters:
        reference - binary reference
        Returns:
        matching blobId, or null

      • getReference

        public java.lang.String getReference​(java.lang.String blobId)
