Class TimedMeasurements

java.lang.Object
  avrora.util.profiling.TimedMeasurements

public class TimedMeasurements

extends java.lang.Object

The TimedMeasurements class implements a simple array-like data structure that collects a large list of integers and supports iterating over that list. For memory-efficient storage, it uses a set of arrays where each array represents a fragment of the measurements obtained.

Nested Class Summary

class	TimedMeasurements.Iterator
static class	TimedMeasurements.Measurement

Constructor Summary

TimedMeasurements()
The default constructor for the Measurements class creates a new instance where the fragment size is 500.

TimedMeasurements(int fragsize)
This constructor for the Measurements class creates a new instance with the specified fragment size.

Method Summary

void	add(long time, int nm) The add() method adds a new measurement to this set.
void	addAll(TimedMeasurements m) The addAll() method adds all of the measurements from another measurement structure to the end of this measurement structure.
long	getLastTime() The getLastTime() method returns the time when the last measurement was recorded.
TimedMeasurements.Iterator	iterator(long startTime) The iterator() method returns an interator over the measurements, starting with the specified measurement.
int	max()
int	min()
int	size() The size() method returns the number of entries in this measurement data.

Constructor Detail

TimedMeasurements

public TimedMeasurements()

The default constructor for the Measurements class creates a new instance where the fragment size is 500.

TimedMeasurements

public TimedMeasurements(int fragsize)

This constructor for the Measurements class creates a new instance with the specified fragment size.

Parameters:

fragsize - the fragment size to use for internal representation

Method Detail

add

public void add(long time,
                int nm)

The add() method adds a new measurement to this set.

Parameters:

time - the time of the measurement

nm - the new measurement to add

iterator

public TimedMeasurements.Iterator iterator(long startTime)

The iterator() method returns an interator over the measurements, starting with the specified measurement.

Parameters:

startTime - the time to start

Returns:

an iterator that will start at the specified measurement and continue until the end

size

public int size()

The size() method returns the number of entries in this measurement data.

Returns:

the number of measurements

addAll

public void addAll(TimedMeasurements m)

The addAll() method adds all of the measurements from another measurement structure to the end of this measurement structure.

Parameters:

m - the measurements to add to the end of this list

getLastTime

public long getLastTime()

The getLastTime() method returns the time when the last measurement was recorded.

Returns:

the time in clock cycles that the last measurement was recorded

min

public int min()

max

public int max()
