공개 메소드들

메소드	설명
CompressMemory ( byte original, int origStart, int origLength, byte changed, int changedStart, int changedLength ) : byte[]	Compresses a block of memory by comparing it with the original version from the game file.
Contains ( string type ) : bool	Checks whether the Quetzal file contains a given chunk type.
DecompressMemory ( byte original, byte delta ) : byte[]	Reconstitutes a changed block of memory by applying a compressed set of differences to the original block from the game file.
FromStream ( Stream stream ) : Quetzal	Loads a collection of chunks from a Quetzal file. Duplicate chunks are not supported by this class. Only the last chunk of a given type will be available.
Quetzal ( ) : System	Initializes a new chunk collection.
WriteToStream ( Stream stream ) : void	Writes the chunks to a Quetzal file.
this ( string type ) : byte[]	Gets or sets typed data chunks.

StrToID ( string type ) : uint

Compresses a block of memory by comparing it with the original version from the game file.

public static CompressMemory ( byte original, int origStart, int origLength, byte changed, int changedStart, int changedLength ) : byte[]
original	byte	An array containing the original block of memory.
origStart	int	The offset within the array where the original block /// starts.
origLength	int	The length of the original block, in bytes.
changed	byte	An array containing the changed block to be compressed.
changedStart	int	The offset within the array where the changed /// block starts.
changedLength	int	The length of the changed block. This may be /// greater than , but may not be less.
리턴	byte[]

Checks whether the Quetzal file contains a given chunk type.

public Contains ( string type ) : bool
type	string	The 4-character type identifier.
리턴	bool

Reconstitutes a changed block of memory by applying a compressed set of differences to the original block from the game file.

public static DecompressMemory ( byte original, byte delta ) : byte[]
original	byte	The original block of memory.
delta	byte	The RLE-compressed set of differences, /// prefixed with a 4-byte length. This length may be larger than /// the original block, but not smaller.
리턴	byte[]

Loads a collection of chunks from a Quetzal file.

Duplicate chunks are not supported by this class. Only the last chunk of a given type will be available.

public static FromStream ( Stream stream ) : Quetzal
stream	Stream	The stream to read from.
리턴	Quetzal

Initializes a new chunk collection.

public Quetzal ( ) : System
리턴	System

Writes the chunks to a Quetzal file.

public WriteToStream ( Stream stream ) : void
stream	Stream	The stream to write to.
리턴	void

Gets or sets typed data chunks.

public this ( string type ) : byte[]
type	string	The 4-character type identifier.
리턴	byte[]
