Public Methods

Method	Description
Allocate ( byte source ) : ByteBuffer	Creates a ByteBuffer loaded with the provided byte array.
Allocate ( int bufferCapacity ) : ByteBuffer	Creates a ByteBuffer with a specified capacity in bytes.
Capacity ( ) : int	Returns the capacity of the ByteBuffer
Get ( ) : byte	Gets the current byte and advances the position by one.
GetDouble ( ) : double	Gets the double floating point number (double) at the current position, and then advances by eight.
GetInt ( ) : int	Gets the 32 bit integer (int) at the current position, and then advances by four.
GetLong ( ) : long	Gets the 64 bit integer (long) at the current position, and then advances by eight.
GetShort ( ) : short	Gets the 16 bit integer (short) at the current position, and then advances by two.
Put ( byte value ) : void	Writes a byte value to the current position, and advances the position by one.
PutDouble ( double value ) : void	Sets the bytes at the current position to the value of the passed value, and advances the position.
PutInt ( int value ) : void	Sets the bytes at the current position to the value of the passed value, and advances the position.
PutInt ( int index, int value ) : void	Sets the bytes at the provided position to the value of the passed value, and does not advance the position. This can be useful for writing a value into an earlier placeholder e.g. a header property for storing the body length.
PutLong ( long value ) : void	Sets the bytes at the current position to the value of the passed value, and advances the position.
ReadFrom ( System source, int length ) : int	Reads from the provided System.IO.Stream, into the buffer.
Remaining ( ) : int	The remaining capacity.

Private Methods

Method	Description
BlockCopy ( Array src, int srcOffset, int dstOffset, int count ) : void
BlockGet ( Array target, int targetOffset, int sourceOffset, int count ) : void
ByteBuffer ( int bufferCapacity ) : System
CheckByteArgument ( byte value, int startIndex, int bytesRequired ) : void	Checks the given argument for validity.
CheckedFromBytes ( byte value, int startIndex, int bytesToConvert ) : long	Checks the arguments for validity before calling FromBytes (which can therefore assume the arguments are valid).
FromBytes ( byte buffer, int startIndex, int bytesToConvert ) : long	Returns a value built from the specified number of bytes from the given buffer, starting at index.
Int64BitsToDouble ( long value ) : double	Converts the specified 64-bit signed integer to a double-precision floating point number. Note: the endianness of this converter does not affect the returned value.
ToArray ( ) : byte[]	Gets a copy of the internal byte array.
ToInt64 ( byte value, int startIndex ) : long	Returns a 64-bit signed integer converted from eight bytes at a specified position in a byte array.

Method Details

Allocate() public static method

Creates a ByteBuffer loaded with the provided byte array.

public static Allocate ( byte source ) : ByteBuffer
source	byte	The source byte array to load the buffer with.
return	ByteBuffer

Allocate() public static method

Creates a ByteBuffer with a specified capacity in bytes.

public static Allocate ( int bufferCapacity ) : ByteBuffer
bufferCapacity	int	The capacity of the buffer in bytes
return	ByteBuffer

Capacity() public method

Returns the capacity of the ByteBuffer

public Capacity ( ) : int
return	int

Get() public method

Gets the current byte and advances the position by one.

public Get ( ) : byte
return	byte

GetDouble() public method

Gets the double floating point number (double) at the current position, and then advances by eight.

public GetDouble ( ) : double
return	double

GetInt() public method

Gets the 32 bit integer (int) at the current position, and then advances by four.

public GetInt ( ) : int
return	int

GetLong() public method
