      • length

        public long length()
                    throws java.io.IOException
        Description copied from interface: FirebirdBlob.BlobOutputStream
        Get Blob length. This method is the only available way to obtain length of a Blob that is in temporary state,
        Specified by:
        length in interface FirebirdBlob.BlobOutputStream
        Returns:
        length of the blob.
        Throws:
        java.io.IOException - if I/O error occurs.
      • write

        public void write​(int b)
                   throws java.io.IOException
        Write single byte into the stream.

        Writes are buffered up to the buffer length of the blob (optionally specified by the connection property blobBufferSize).

        Specified by:
        write in interface FirebirdBlob.BlobOutputStream
        Specified by:
        write in class java.io.OutputStream
        Parameters:
        b - data to write, only lowest 8 bits are written.
        Throws:
        java.io.IOException - if I/O error occurs.
      • write

        public void write​(byte[] b,
                          int off,
                          int len)
                   throws java.io.IOException
        Write data from the buffer into this stream.

        Writes are buffered up to the buffer length of the blob (optionally specified by the connection property blobBufferSize).

        Specified by:
        write in interface FirebirdBlob.BlobOutputStream
        Overrides:
        write in class java.io.OutputStream
        Parameters:
        b - buffer from which data should be written.
        off - offset in the buffer.
        len - number of bytes to write.
        Throws:
        java.io.IOException - if I/O error occurs.
      • flush

        public void flush()
                   throws java.io.IOException
        Specified by:
        flush in interface java.io.Flushable
        Overrides:
        flush in class java.io.OutputStream
        Throws:
        java.io.IOException
      • close

        public void close()
                   throws java.io.IOException
        Description copied from interface: FirebirdBlob.BlobOutputStream
        Close this stream. Calling this method closes Blob stream and moves Blob from temporary into permanent state making any further content updates impossible.
        Specified by:
        close in interface java.lang.AutoCloseable
