Creates a PageHandle to access the next.

Parameters

n	bytes of the Page.

void read	(	PageHandle::Ptr &	pageHandle,
		std::streamsize	n,
		bool	delayed = true
	)

Takes a pageHandle and updates the referenced page with the current stream pointer position and if delayed is false performs an immediate read of the data.
