public interface IClob
An optional interface that represents a Character Large Object (CLOB) value.  
 
The interface must be implemented only if the ODA driver 
 supports the CLOB data type.
 
The IClob interface provides methods for retrieving a CLOB value
 as a Java stream that can be read in smaller chunks, and
 for optionally getting the length of a CLOB value.
 
 The interface method IResultSet.getClob returns 
 an IClob instance.
| Method Summary | |
|---|---|
|  java.io.Reader | getCharacterStream()Retrieves the CLOB value designated by this IClob instance as a java.io.Reader object for reading a stream of characters. | 
|  java.lang.String | getSubString(long position,
             int length)Retrieves a copy of the specified substring in the CLOB value designated by this IClob instance. | 
|  long | length()Returns the number of characters in the CLOB value designated by this IClob object. |
