Class StartEndTracer

java.lang.Object

overit.geocall.util.tracer.MemoryTracer

overit.geocall.util.tracer.StartEndTracer

All Implemented Interfaces:

Serializable, Tracer

public class StartEndTracer
extends MemoryTracer
implements Serializable

This class extends the abstract class MemoryTracer and creates an instance of the tracer.
This tracer put in the register the first 'n/2' rows and the last 'n/2' rows, where 'n' is the value of the parameter passed to the constructor StartEndTracer(maxSize).
Usually the 'maxSize' corresponds to the value ThreadContext.MAX_MEMORY_TRACE_SIZE.

Constructors

Constructor	Description
StartEndTracer(int maxSize)	Class constructor using the first parameter to determine the maximum registry length. The maximum length will be splitted in two equals part, so the first rows will be placed in the registry up to half the maximum length and the same thing for the last rows.
