All Implemented Interfaces:

NameContext, NameContextBindingListener, NameContextElement, java.io.Serializable, java.lang.Cloneable, java.util.EventListener, java.util.Map<java.lang.String,PerformanceData>

public class PerformanceHashtable
extends atg.core.util.WrapperHashtable<java.lang.String,PerformanceData>
implements NameContext, NameContextBindingListener

This class stores the performance objects for operations. Also, it stores the totals for all the parameterized operations stored within the hash.

When endOperation is called, it gets the PerformanceStackData object. Some calculations are performed and then the totals are put into a PerformanceData object which is stored into this hashtable. The totals from this object are also added to the PerformanceData object contained within this object.
