V.Narayanan updated DERBY-1328:
-------------------------------
Attachment: ClobBlob_free_v1.diff
ClobBlob_free_v1.stat
Implementation of free() methods in Clob and Blob interface
Involves freeing the resources that are used by the Clob and Blob
implementation once the free() method is called on these interfaces. Most of
the cases this involved closing the streams that were used in the
implementation. Any IO Exception that may occur during the closing of these
streams is wrapped as a SQLException and returned to the user.
Calling a free on a Clob or a Blob on which free has already been called is a
no-op. When any other method in the Clob or Blob interface is called after free
is called then an SQLException is raised.
When free is called on either a Clob or a Blob a boolean variable isValid is
set to false. This variable is checked each time any method on a Clob or Blob
interface is called. If found to be false a SQLExeption is thrown. By default
isValid = true.
A function checkValidity() has been introduced on the interfaces to check for
the isValid variable and return an appropriate SQLException.
