It is mostly implemented in C++, because it is mainly usedinternally and little functionality is needed by users. It has thefollowing major C++ methods:<P><UL><LI><TT>get_page(const char* name)</TT> - Returns a pointer to the page with the given name. </LI><LI><TT>add_page(const char *name, int size, double mt, double et, double age)</TT> - Add a page with given size, last modification time (mt), cache entry time (et), and page lifetime (age). </LI><LI><TT>remove_page(const char* name)</TT> - Remove a page from cache.</LI></UL><P>This page pool should support various cache replacement algorithms,however, it has not been implemented yet. <P><BR><HR><ADDRESS>2003-09-23</ADDRESS></BODY></HTML>⌨️ 快捷键说明
