/** @file PageReplacementScheme.hpp * @brief PageReplacementScheme class implementation file * * @author Student Name * @note cwid: 123456 * @date Fall 2019 * @note ide: g++ 8.2.0 / GNU Make 4.2.1 * * Implementation file for our PageReplacementScheme class. The PageReplacementScheme * class is an abstract base class that defines the interface * for implementing different page replacement schemes. * Basically any page replacement scheme needs to be able to * select a physical frame of memory to be replaced, using whatever * algorithm the scheme implements. This abstract interface * defines the api calls supported so that the PagingSystem * simulator can use any particular PageReplacementScheme. */ #include "PageReplacementScheme.hpp" /** * @brief constructor * * The basic constructor is called by the PagingSystem when setting up/creating * the paging scheme to use for a simulation. We keep track of the paging system * instance we are associated with, so we can call the paging system to get * needed information to make replacment decisions. * * @param sys The associated PagingSystem system instance that this scheme * is associated with. */ PageReplacementScheme::PageReplacementScheme(PagingSystem* sys) { this->sys = sys; } /** * @brief destructor * * Define a concrete destructor. This destructor has no work to do, but * base classes that need a destructor should define their own. */ PageReplacementScheme::~PageReplacementScheme() { }
