Put End Of Stream marker.

bool IsGetReady() const

Is some data ready ?
true = yes.

DataT Get()

Get next piece of data.
May block if not ready, or it will return a constructed with the default constructor.

DataT Get()

Get next piece of data.
May block if not ready, or it could throw an DataNotReadyC exception. NB. This function MUST be provided by client class.

bool Get(DataT & buff)

Try and get next piece of data.
This may not NOT block, if no data is ready it will return false, and not set buff. NB. The default version of this function uses the Get() method defined above and so need not be provided by derived classes.

IntT GetArray(SArray1dC<DataT> & data)

Get an array of data from stream.
returns the number of elements succesfully processed. NB. This need NOT be overridden in client classes unless fast handling of arrays of data elements is required.

bool Put(const DataT &)

Put data.
This function MUST be provided by client class.

IntT PutArray(const SArray1dC<DataT> & data)

Put an array of data to stream.
returns number of elements processed. NB. This need NOT be overridden in client classes unless fast handling of arrays of data elements is required.
