com.quadcap.sql.io.DataOutputStream Class Reference

Inheritance diagram for com.quadcap.sql.io.DataOutputStream:

OutputStream DataOutput com.quadcap.sql.io.ObjectOutputStream List of all members.

Detailed Description

This class implements data output somewhat more efficiently than the JDK version.

It also implements buffering and counting, to help us avoid extra layers of stream classes.

4/2/03: XX What JDK version? this hasn't been examined recently...
