ClobImpl (Castor 1.3.2 API)

java.lang.Object
- org.exolab.castor.jdo.engine.ClobImpl

All Implemented Interfaces:

Clob
```
public class ClobImpl
extends Object
implements Clob
```
This is an implementation of java.sql.Clob interface that is constructed from java.io.Reader, in needs information about the length of the stream (which is not provided by java.io.Reader interface).
It is useful for setting CLOB values in the database.
Note: This implementation does not attempt to implement features of JDBC3 or JDBC4.
