Making a Post-transaction Filter

To make a post-transaction filter, create a Java class that extends the abstract class neo.xredsys.api.services.PostTransactionFilterService. This is a convenience class containing empty "do nothing" implementations of the methods defined in the neo.xredsys.api.PostTransactionFilter interface:

doPostCreate(object)

which is executed immediately after a new object is saved.

doPostUpdate(object)

which is executed immediately after changes to an existing object are saved.

doPostDelete(object)

which is executed immediately after an existing object is deleted.

isEnabled()

which is called by the Content Engine to determine whether or not the filter is currently enabled.

Before a post-transaction filter can be used it must be:

• Compiled

• Added to the Content Engine's classpath

To compile a post-transaction filter you need the Escenic JAR file engine-core-5.4.7.169266.jar in your classpath.
