sqlj.runtime.CharacterStream Class
sqlj.runtime.CharacterStream Class
A Reader-derived class that represents an input stream of bytes. The bytes of a
CharacterStream object are interpreted as Unicode characters.
To pass a Reader object as an input parameter (host variable or expression) to an
SQL statement, you must provide the SQLJ run time with the length of the Reader.
Therefore, SQL operations in an SQLJ application accept instances of the
CharacterStream class instead of direct references to Reader objects.
