3.1 LibraryTime Class Reference

#include <LibraryTime.h>

Public Member Functions

• LibraryTime ()

• void Start (void)

• void Stop (void)

• double Get (void)

• void Delay (const int miliseconds)

• virtual ∼LibraryTime ()

3.1.1 Detailed Description

Classe que executa verificação de tempo decorrido para realização de determinadas tarefas. Usada parafazer análise de complexidade computacional em relação a quanto tempo um determinado trecho de códigoconsome para ser realizado. O retorno é dado em milisegundos com base no clock da máquina.

3.1.2.2 virtual LibraryTime::∼LibraryTime () [inline, virtual]

Método destrutor da classe responsável por desalocar quaisquer recursos previamente alocados retornandoos mesmos ao sistema.


00066 {};

3.1.3 Member Function Documentation

3.1.3.1 void LibraryTime::Delay (const int miliseconds) [inline]

Método que imprime uma pausa em milisegundos na execução do fluxo do programa a partir do ponto ondeela foi chamada.


00060 { clock_t exit_time = clock() + miliseconds; while(clock() <= exit_time); }

3.1.3.2 double LibraryTime::Get (void) [inline]

Método responsável por retornar o intervalo em milisegundos decorrido entre as chamadas dos métodoStart() e Stop()


00053 { return double( stop - start )/CLOCKS_PER_SEC; }

Here is the caller graph for this function:

LibraryTime::Get main

3.1.3.3 void LibraryTime::Start (void) [inline]

Método responsável por capturar o tempo ou intervalo inicial de execução de alguma operação.


00041 { start = clock(); }


LibraryTime::Start main
