Constructor & Destructor Documentation

HexenThings::HexenThings (  const Lump &  lump  )  throw ()

Construct from a Lump. Constructs a HexenThings object given raw Lump data. The constructor parses the Lump into integers and creates Thing objects from them. It then stores them in order inside of itself. Parameters: lump  Source Lump from which to pull HexenThing data. Definition at line 336 of file things.cpp. References setFromLump().

HexenThings::~HexenThings (  void   )  throw () [virtual]

Destructor. Does nothing, but is necessary for inheritance. Definition at line 347 of file things.cpp.

Member Function Documentation

bool HexenThings::setFromLump (  const Lump &  lump  )  throw () [virtual]

Convert a Lump to this entry. Lumps should not know about specific data structures. Those structures know about Lumps, including how to convert from them. Setting from a Lump involves parsing that Lump's contents to see if they are valid. If they are, then this object will contain what you expect it to. If not, it will return false and the atomic operation will not succeed. Parameters: lump  Reference to a source Lump object. Returns: True if successful, false if not. Implements Doomwad::WadEntry. Definition at line 352 of file things.cpp. References Doomwad::HexenThing::read(), and Doomwad::Lump::size(). Referenced by HexenThings().

Lump HexenThings::toLump (  void   )  const throw () [virtual]

Convert this entry to a Lump. Each subclass must be able to convert itself to a Lump for storage in a Wad. Returns: Lump containing the raw file representation of this entry. Implements Doomwad::WadEntry. Definition at line 370 of file things.cpp. References NAME.

std::string HexenThings::toString (  void   )  const throw () [virtual]

Convert this entry to a std::string. The exact implementation varies by the exact concrete class, but the idea is to convert the entry into a summary to be displayed to the user. Please note that converting to a string may lose information. This is not serialization in the purest sense of the word, this is merely a quick and dirty user-readable summary of the entry. True serialization is achieved by converting a Lump object and using its stream I/O functions to read and write. Returns: std::string containing a summary of this entry. Implements Doomwad::WadEntry. Definition at line 384 of file things.cpp.
