Class MetricOnDemandListener

java.lang.Object
  org.apache.muse.ws.dm.muws.impl.MetricOnDemandListener

All Implemented Interfaces:

PropertyReadListener

public class MetricOnDemandListener

extends java.lang.Object

implements PropertyReadListener

MetricOnDemandListener is a simple property listener that makes sure an OnDemand metric's timestamps are updated for each property read that occurs. Because OnDemand metrics are collected on a need-to-know basis, we must update metric metadata to reflect new values even if they didn't come from a property insert/update/etc.

public MetricOnDemandListener(Metric metric)

Method Detail

getPropertyName

public QName getPropertyName()

Specified by:

getPropertyName in interface PropertyReadListener

Returns:

The name of the property to monitor.

readRequested

public org.w3c.dom.Element[] readRequested(org.w3c.dom.Element[] properties)

Specified by:

readRequested in interface PropertyReadListener

Parameters:

properties - The actual property values that will be returned to the caller at the end of the read operation. WS-RP collections should not pass copies of the values to a listener, since that prevents the ability to define dynamic property values (properties that constantly change and are only updated on read requests).
