Methods

template <typename T>
static void writeBitKey(T* Key, unsigned int Pos, unsigned int BitWrite)

Write a bit into the Key in the position defined.

Parameters:

Key	The Key to write
Pos	The Position of the bit
BitWrite	0 for write 0, any other to write 1.

template <typename T>
static bool readBitKey(T* Key, Uint32 Pos)

Read a bit from a 32 bit key, in the position defined

Parameters:

Key	The Key to read
Pos	The Position in the key to read

Returns:

True if the bit is 1

template <typename T>
static void setBitFlagValue(T* Key, Uint32 Val, Uint32 BitWrite)

Write a bit flag value

Parameters:

Key	The Key to write or remove
Val	The Value to write or remove
BitWrite	0 to remove, any value to write
