Class PDSEncoder.RewriteCheckingDecodeObjectInputStream

java.lang.Object
  java.io.InputStream
      java.io.ObjectInputStream
          wt.pds.PDSEncoder.DecodeObjectInputStream
              wt.pds.PDSEncoder.RewriteCheckingDecodeObjectInputStream

All Implemented Interfaces:

DataInput, ObjectInput, ObjectStreamConstants, PDSObjectInput

Enclosing class:

PDSEncoder

static class PDSEncoder.RewriteCheckingDecodeObjectInputStream

extends PDSEncoder.DecodeObjectInputStream

This class exists to deal with bad versions of the wt.meta.LocalizedValue class if they're encountered during (small)blob decodings.
