Constructor Details

TimeValueProcessor

public TimeValueProcessor()

Constructor for TimeValueProcessor.

TimeValueProcessor

public TimeValueProcessor(String format)

Constructor for TimeValueProcessor.

Parameters:

format - a String object

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.

process

public void process()

Called by Database in interval set by the trigger parameter in milliseconds. Not called if trigger in 0.

Specified by:

process in interface ValueProcessor

Overrides:

process in class AbstractValueProcessor

process

public Object process(long time,
 gov.aps.jca.dbr.Severity severity,
 gov.aps.jca.dbr.Status status,
 boolean notify)

process.

Parameters:

time - a long

severity - a Severity object

status - a Status object

notify - a boolean

Returns:

a Object object

convert

public Object convert(long time)

convert.

Parameters:

time - a long

Returns:

a Object object

propertyChange

public void propertyChange(PropertyChangeEvent evt)

Specified by:

propertyChange in interface PropertyChangeListener

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
