Method Details

configure

public void configure(Record record,
 org.apache.commons.configuration.HierarchicalConfiguration config)

Configures the internals of value processor, provides reference to parent record and to configuration with root inside processor tag. Parent record 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 ValueProcessor

Overrides:

configure in class MemoryValueProcessor

Parameters:

record - the parent record.

config - configuration with room inside processor tag.

activate

public void activate()

Record has now reference to Database. processor 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 to the processor that records has been loaded and linking to other values can be commenced.

Specified by:

activate in interface ValueProcessor

Overrides:

activate in class MemoryValueProcessor

propertyChange

public void propertyChange(PropertyChangeEvent evt)

Specified by:

propertyChange in interface PropertyChangeListener
