Class InputStreamBlob

java.lang.Object
  org.apache.lucene.store.jdbc.support.InputStreamBlob

All Implemented Interfaces:

Blob

public class InputStreamBlob
extends Object
implements Blob

A helper class that can wrap an InputStream as a Jdbc Blob.

Some jdbc drivers do not support the PreparedStatement.setBinaryStream(int, java.io.InputStream, int) method, but require using PreparedStatement.setBlob(int, java.sql.Blob). For code that already has an InputStream ready, this Blob implementation can help.
