public class SimpleMetrics
extends AbstractManageabilityCapability
implements Metrics

SimpleMetrics is Muse's default implementation of the WSDM Metrics capability. It uses the WS-RP and WS-RMD implementations in Muse to collect metric metadata and expose it to WS-RP clients without requiring users to treat metric and non-metric properties differently in their code. Metrics that are defined in a resource's RMD have various property change listeners and approvers set up for them so that all metadata is kept up-to-date.

Constructor Detail

SimpleMetrics

public SimpleMetrics()
Method Detail

getCurrentTime

public Date getCurrentTime()
Specified by:
getCurrentTime in interface Metrics
Returns:
The current time, according to the resource or its manager.

getMetric

public Metric getMetric(QName propertyQName)
Specified by:
getMetric in interface Metrics
Parameters:
propertyQName - The name of the property that is also defined as a metric.
Returns:
The collection of metric metadata for the property, or null if the property does not exist.

getPropertyNames

public QName[] getPropertyNames()
Concrete capability classes that define properties MUST override this method and provide the names of the properties.

Overrides:
getPropertyNames in class AbstractWsResourceCapability
Returns:
The names of the resource properties defined by this capability.

initialize

public void initialize()
                throws SoapFault
Description copied from class: AbstractWsResourceCapability


AbstractWsResourceCapability continues the initialization process by inspecting the concrete class to find all of the getters (and, if applicable, setters) for its resource properties. It then registers itself with the resource's WSRP collection so that read and write requests for its properties are delegated to it.

Specified by:
initialize in interface Initialization
Overrides:
initialize in class AbstractWsResourceCapability
Throws:
SoapFault

shutdown

public void shutdown()
              throws SoapFault
Specified by:
shutdown in interface Shutdown
Overrides:
shutdown in class AbstractCapability
Throws:
SoapFault

deleteProperty

public void deleteProperty(QName property)
                    throws BaseFault
Throws:
BaseFault

getProperty

public Element[] getProperty(QName property)
                      throws BaseFault
Throws:
BaseFault

insertProperty

public void insertProperty(QName property,
                           Element[] values)
                    throws BaseFault
Throws:
BaseFault

updateProperty

public void updateProperty(QName property,
                           Element[] values)
                    throws BaseFault
Throws:
BaseFault
