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.


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 Detail

close

void close()
           throws java.io.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:
java.io.IOException - if I/O error occurs.

length

long length()
            throws java.io.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:
java.io.IOException - if I/O error occurs.

write

void write(byte[] buffer,
           int offset,
           int length)
           throws java.io.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:
java.io.IOException - if I/O error occurs.

write

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