org.exolab.castor.jdo.engine.ClobImpl
- Clob
public class ClobImpl
extends java.lang.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.
ClobImpl(Reader reader, long length) - Examples:
new ClobImpl(new StringReader(str), str.length())
new ClobImpl(new FileReader(file), file.length())
