Detailed Description
An input stream over elements of type "T" that reads from user-specified explicit offsets.
Public Types
typedef T ElementType
typedef Offset OffsetType

Public Functions
readAt(OffsetType offset, T * buffer, U32 num)
Read the next "num" elements at "offset" into "buffer".
Parameters:
| offset | The offset in the stream from which to read. |
| buffer | The buffer into which the elements are stored. |
| num | Number of elements to read. |
return:
the number of elements actually read; this may be less than "num" or even zero if no elements are available or reading failed.
