Method Details

configure

public void configure(String name,
 org.apache.commons.configuration.HierarchicalConfiguration config)

Configures the internals of this application, provides reference to configuration with root inside applications tag. Server structure is not yet initialized, so does not have reference to Database, the Database reference will be available during activate call.

Specified by:

configure in interface Application

Overrides:

configure in class AbstractApplication

Parameters:

name - a String object

config - configuration with room inside application tag.

activate

public void activate()

Application has now reference to Database. Application might want to connect to other records on this server or PVs on other servers. This can not be done until all records from configuration has been loaded. Call to this method signals application that records has been loaded and linking to other values can be commenced.

Specified by:

activate in interface Application

Overrides:

activate in class AbstractApplication

notifyRecordChange

protected void notifyRecordChange(String name,
 boolean alarmOnly)

This method is called whenever record value changed for any record, which belongs to this application (it was added to the application AbstractApplication.addRecord(String, Record)). Implementation class should override this method to intercept the update.

Overrides:
