Interface FirebirdBlob.BlobOutputStream

All Known Implementing Classes:
FBBlobOutputStream
Enclosing interface:
FirebirdBlob
public static interface FirebirdBlob.BlobOutputStream
Blob output stream. This interface defines methods to write contents of the Blob field. Some method signatures are copied from the OutputStream only because it is abstract class and not interface that we can extend.

    Write single byte into the stream.

  • Method Details

    • getBlob

      FirebirdBlob getBlob()
      Get instance of FirebirdBlob to which this stream belongs to.

      Note, code 

       FirebirdBlob.BlobOutputStream otherStream = (FirebirdBlob.BlobOutputStream)
     inputStream.getBlob().setBinaryStream(1);
      will return new stream object.
      Returns:
      instance of FirebirdBlob.

    • close

      void close() throws IOException
      Close this stream. Calling this method closes Blob stream and moves Blob from temporary into permanent state making any further content updates impossible.
      Throws:
      IOException - if I/O error occurs.

    • length

      long length() throws IOException
      Get Blob length. This method is the only available way to obtain length of a Blob that is in temporary state,
      Returns:
      length of the blob.
      Throws:
      IOException - if I/O error occurs.

    • write

      void write(byte[] buffer, int offset, int length) throws IOException
      Write data from the buffer into this stream.
      Parameters:
      buffer - buffer from which data should be written.
      offset - offset in the buffer.
      length - number of bytes to write.
      Throws:
      IOException - if I/O error occurs.

    • write

      void write(int data) throws IOException
      Write single byte into the stream.
      Parameters:
      data - data to write, only lowest 8 bits are written.
      Throws:
      IOException - if I/O error occurs.
