Class SelectsMediaRecorder

java.lang.Object
  com.ap.jdbcunit.SelectsMediaRecorder

All Implemented Interfaces:

Recorder

public class SelectsMediaRecorder

extends java.lang.Object

implements Recorder

A recorder that records only SELECT sql statements, it fails if some other statement is executed (like insert, update or delete).

This recorder is a light recorder implementation targeted for "read-only" JDBC applications.

This recorder is a light recorder because it easily can decide it some statement was already recorded and pick up the previous result. It also doesn't need to have any strategy about track versioning, all the tracks are version 1.

Finally, the recorded application can change, provided the same statements are reused, and still the recorded data remain valid.
