java.sql.SQLException

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

Description copied from interface: FirebirdBlob.BlobOutputStream

Write single byte into the stream.

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.

writeSegment

public void writeSegment(byte[] buf)
                  throws GDSException

Throws:

GDSException

write

public void write(byte[] b,
                  int off,
                  int len)
           throws java.io.IOException

Description copied from interface: FirebirdBlob.BlobOutputStream

Write data from the buffer into this stream.

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.

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.io.Closeable

Specified by:

close in interface FirebirdBlob.BlobOutputStream

Overrides:

close in class java.io.OutputStream

Throws:

java.io.IOException - if I/O error occurs.
