Private Attributes

Poco::SharedPtr< std::vector
< char > > 
 Returns the size of the BLOB in bytes.


class BLOBStreamBuf

Detailed Description

Representation of a Binary Large OBject.

A BLOB can hold arbitrary binary data. The maximum size depends on the underlying database.

The BLOBInputStream and BLOBOutputStream classes provide a convenient way to access the data in a BLOB.
