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.

extract

protected double[] extract(Record input)

Implementation must extract array data from record. Any data manipulation should be applied here.

Parameters:

input - a Record object

Returns:

an array of

invalid reference

double

objects

update

protected void update()

update.

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:

notifyRecordChange in class AbstractApplication

Parameters:

name - the name of record, that triggered change.

alarmOnly - if true then only alarm has been changed
