Comments:
This is a BIG object.

Mechanism suggested by G.Matas.

RandomBagC(IntT Size = 0)

Constructor.

RandomBagC(const SArray1dC<T> & data)

Construct from an array of data.
this assumes that all the entries in 'data' are valid.

NB. This does NOT copy the data from the array and will leave its contents is an unspecified state.

RandomBagC(const RandomBagC & Oth)

~RandomBagC()

Destructor

const RandomBagC<T> & operator=(const RandomBagC & Oth)

Assignment.

void Reset(IntT Size)

Empty pool and set to new size.

BooleanT Insert(const T & Px)

Add new data to pool, returns false if pool is full.

void Resize(SizeT nSize)

Change the size of the pool (Slow).

T Pick(void)

Pick a data item at random from the pool.
NB. Only use if you know the pool is not empty, this can be tested by IsElm().

BooleanT IsEmpty() const

Is pool empty ?

BooleanT IsElm() const

Does pool contain any data ?

void Empty()

Empty it of all data.

IntT Size() const

Number of elements in the pool.
