Class BlobImpl

java.lang.Object
  org.apache.derbyTesting.functionTests.tests.largedata.BlobImpl

All Implemented Interfaces:

java.sql.Blob

 class BlobImpl
extends java.lang.Object
implements java.sql.Blob

Class to simulate a 4Gb blob impl in order to test if Derby handles such large blobs correctly. The main methods here are only the length() and the getBinaryStream(). Rest are just placeholders/dummy methods in order to implement the java.sql.Blob interface ---- Derby throws an error if the blob length exceeds the max range of int.
