Class BlobProxy

java.lang.Object
  extended by org.hibernate.engine.jdbc.BlobProxy
All Implemented Interfaces:
InvocationHandler

public class BlobProxy
extends Object
implements InvocationHandler

Manages aspects of proxying Blob references for non-contextual creation, including proxy creation and handling proxy invocations. We use proxies here solely to avoid JDBC version incompatibilities.
