.new
.read(io : IO, file_offset : UInt32 = 0) : Directory
Read an io from the WAD and convert it into a Directory.

#clone
Returns a copy of self with all instance variables cloned.
#file_pos : UInt32
An integer holding a pointer to the start of the lump's data in the file.
#file_pos=(file_pos : UInt32)
An integer holding a pointer to the start of the lump's data in the file.
#initialize
#name : String
An ASCII string defining the lump's name.
#name=(name : String)
An ASCII string defining the lump's name.
#size : UInt32
An integer representing the size of the lump in bytes.
#size=(size : UInt32)
An integer representing the size of the lump in bytes.

def self.new #

def self.read(io : IO, file_offset : UInt32 = 0) : Directory #

Read an io from the WAD and convert it into a Directory.

Reads a directory from a WAD file with directory_start and Directory::SIZE:

file.read_at(directory_start, Directory::SIZE) do |io|
  directory = Directory.read(io)
end

NOTE file_offset is used when the start of the WAD is offset in a file

def clone #

Returns a copy of self with all instance variables cloned.

def initialize #

def name : String #

An ASCII string defining the lump's name.

def name=(name : String) #

An ASCII string defining the lump's name.

def size : UInt32 #

An integer representing the size of the lump in bytes.

def size=(size : UInt32) #

An integer representing the size of the lump in bytes.
