Class SessionClearingRowCallbackHandler

java.lang.Object
  com.atlassian.confluence.upgrade.upgradetask.SessionClearingRowCallbackHandler

All Implemented Interfaces:

org.springframework.jdbc.core.RowCallbackHandler

public abstract class SessionClearingRowCallbackHandler
extends java.lang.Object
implements org.springframework.jdbc.core.RowCallbackHandler

Implementation of RowCallbackHandler which clears the session after processing a configurable number of rows. Subclasses should implement processRowInternal(ResultSet) to do their specific processing. If you need a custom flushing and clearing strategy (not after a certain number of rows), you can write your own RowCallbackHandler and use flushAndClear(Session) to do the flushing.
