All Implemented Interfaces:

ObservablePathProvider, Device, Configurable, Findable, gda.observable.IObservable, gda.observable.IObserver, org.springframework.beans.factory.InitializingBean

public class ObservablePathConstructor
extends DeviceBase
implements ObservablePathProvider, gda.observable.IObserver, org.springframework.beans.factory.InitializingBean

An ObservablePathProvider that when configured with a template of the form expected by PathConstructor creates a path using PathConstructor. A PathChanged event is sent to registered Observers when any MetadataEntry referenced by the template changes.

Description copied from class: ConfigurableBase

Default implementation for classes that do not have to do any specific configuration.
Classes that do their own configuration should *not* call this superclass function, as it may cause the object to appear configured before it really is.

Specified by:

configure in interface Configurable

Overrides:

configure in class ConfigurableBase

Throws:

FactoryException - if there is an error in configuration e.g. required variable not set or cannot connect to device

getPath

public String getPath()

Specified by:

getPath in interface ObservablePathProvider

setGdaMetadata

public void setGdaMetadata(GdaMetadata gdaMetadata)

getGdaMetadata

public GdaMetadata getGdaMetadata()

getReferedMetadataEntries

public List<IMetadataEntry> getReferedMetadataEntries()

update

public void update(Object source,
 Object arg)

Specified by:

update in interface gda.observable.IObserver

afterPropertiesSet

public void afterPropertiesSet()
                        throws Exception

Specified by:
