Public Methods

Method	Description
MemCpy ( [ src, [ dest, int len ) : void	Copies contents of src buffer to dest buffer, as efficiently as possible.
MemSet ( [ array, byte value ) : void	Fills the entire given byte array with a specified byte value, as efficiently as possible.
MemSet ( [ array, byte value, int startIndex, int length ) : void	Fills a section of the given byte array with a specified byte value, as efficiently as possible.
ReadAll ( [ source, [ destination ) : void	Reads a number of bytes from source that matches the length of destination byte array.
WriteAll ( [ source, [ destination ) : void	Writes contents of given byte array to a stream, in chunks of at most 512 MiB. Works around an overflow in BufferedStream.Write(byte[]) that happens on 1 GiB+ writes.

Method Details

MemCpy() public static method

Copies contents of src buffer to dest buffer, as efficiently as possible.

public static MemCpy ( [ src, [ dest, int len ) : void
src	[	Source array/pointer.
dest	[	Destination array/pointer.
len	int	Number of bytes to copy.
return	void

MemSet() public static method

Fills the entire given byte array with a specified byte value, as efficiently as possible.

array is null.

public static MemSet ( [ array, byte value ) : void
array	[	Array to work with.
value	byte	Value to assign to each byte of the array.
return	void

MemSet() public static method

Fills a section of the given byte array with a specified byte value, as efficiently as possible.

array is null. length is negative; startIndex is negative; /// or if (length+startIndex) is greater than array length.

public static MemSet ( [ array, byte value, int startIndex, int length ) : void
array	[	Array to work with.
value	byte	Value to assign to each byte of the array.
startIndex	int	Index of the first byte that should be set.
length	int	Number of bytes of the array to set.
return	void

ReadAll() public static method

Reads a number of bytes from source that matches the length of destination byte array.

source or destination is null. The end of stream is reached before destination array was filled.

public static ReadAll ( [ source, [ destination ) : void
source	[	Stream to read from.
destination	[	Byte array to write to. Length of this array is used.
return	void

WriteAll() public static method

Writes contents of given byte array to a stream, in chunks of at most 512 MiB. Works around an overflow in BufferedStream.Write(byte[]) that happens on 1 GiB+ writes.

source or destination is null.

public static WriteAll ( [ source, [ destination ) : void
source	[	Byte array to read from. Must not be null.
destination	[	Stream to write to. Must not be null.
return	void
