public class CacheMarshaller210
extends CacheMarshaller200

An evolution of CacheMarshaller200, created to fix JBCACHE-1211.

To prevent ints taking too much space, they are written as variable-length ints. Details here on VInts.

Since:

2.1.0

Method Detail

writeReference

protected void writeReference(ObjectOutputStream out,
                  int reference)
                       throws IOException

This version of writeReference is written to solve JBCACHE-1211, where references are encoded as ints rather than shorts.

Overrides:

writeReference in class CacheMarshaller200

Parameters:

out - stream to write to

reference - reference to write

Throws:

IOException - propagated from OOS

See Also:

JBCACHE-1211

readReference

protected int readReference(ObjectInputStream in)
                     throws IOException

This version of readReference is written to solve JBCACHE-1211, where references are encoded as ints rather than shorts.

Overrides:

readReference in class CacheMarshaller200

Parameters:

in - stream to read from

Returns:

reference

Throws:

IOException - propagated from OUS
