Class PerformanceStackData

java.lang.Object
  atg.service.perfmonitor.PerformanceStackData

All Implemented Interfaces:

Resetable

public class PerformanceStackData
extends java.lang.Object
implements Resetable

This class represents an operation, possibly parameterized, during runtime. It contains the name of an operation, an optional parameter, and the start time. The optional parameter should be the object that the given operation is operating on. The start time is stored in milliseconds since Jan 1, 1970.

When startOperation is called in PerformanceMonitor, an object of this type is retrieved from the pool, populated, and added to the mThreadStackHash table in the PerformanceMonitor. When endOperation is called, it is popped off the stack and its start time is used to determine stats for the specified operation.
