little discription about these MFRC522 codes

hi every body

i want to use mfrc522 mbed library in keil compiler & dont want to export codes directrly but i have some problem with these codes

MFRC522.h

class MFRC522 {
public:
.........
.........
.........
  /**
  * MFRC522 constructor
  *
  * @param mosi  SPI MOSI pin
  * @param miso  SPI MISO pin
  * @param sclk  SPI SCLK pin
  * @param cs    SPI CS pin
  * @param reset Reset pin
  */
  MFRC522(PinName mosi, PinName miso, PinName sclk, PinName cs, PinName reset);

  /**
  * MFRC522 destructor
  */
  ~MFRC522();


private:
  SPI              m_SPI;
  DigitalOut       m_CS;
  DigitalOut       m_RESET;

};

i know about classes & have some experiences in c++ compiler show errors about unknown type names :PinName, SPI & DigitalOut perhaps <<code>> DigitalOut m_CS;<</code>> defines chip select pin as output & m_RESET is same but whats meaning of <<code>> DigitalOut m_RESET;<</code>> defines chip select pin as output & m_RESET is same but whats meaning of <<code>> DigitalOut m_RESET;<</code>> ? what does it work ? & whats function & type of PinName? what dose it do? whats differences between PinName cs & DigitalOut m_CS;

tnaks every body
