Interface FirebirdBlob.BlobOutputStream

Known Implementing Classes:
FBBlob.FBBlobOutputStream

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.

Method Summary

void
close()
Close this stream.
long
length()
Get Blob length.
void
write(byte[] buffer, int offset, int length)
Write data from the buffer into this stream.
void
write(int data)
Write single byte into the stream.

Method Details

close

public 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.

length

public 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.

write

public 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.

write

public void write(int data)
            throws IOException
Write single byte into the stream.
Parameters:
