Interface CpdData

  • All Superinterfaces:
    java.lang.Cloneable, CpdEventSender, CpdXML,

    As of 6.0, PMI Client API is replaced with JMX interface and MBean StatisticsProvider model. PMI CpdCollection data structure is replaced by J2EE Performance Data Framework defined in package.

    The CpdData is a 4.0 class and will be supported in 5.0. It contains the config info and an object of CpdDouble, CpdLong, CpdLoad, or CpdStat depending on the data type.

    The CpdData object is the lowest level in the data hierarchy. Each CpdData instance contains all the static information for the performance data and a getValue method to return the data dynamic information, in the form of an instance of the CpdValue object. The CpdData interface provides an update method to take a reference to a new version of a piece of data and update the current object with the new value. The value is updated only if the new data has the same name as the original object. The CpdData interface also includes an addListener interface to enable data objects to register as event listeners; see The CpdEventListener and CpdEvent interfaces for details. The CpdData interface extends the CpdXML and CpdEventSender interfaces, which are shown in the definition located in that section.
