Detailed Description

template<class T, class B, bool A = false>
class GetBlock< T, B, A >

Access a block of memory.

Template Parameters

T	class or type
B	enumeration indicating endianness
A	flag indicating alignment

GetBlock() provides alternate read access to a block of memory. The enumeration B is BigEndian or LittleEndian. The flag A indicates if the memory block is aligned for class or type T. Repeatedly applying operator() results in advancing in the block of memory.

An example of reading two word32 values from a block of memory is shown below. w1 will be 0x03020100 and w1 will be 0x07060504.

   word32 w1, w2;
   byte buffer[8] = {0,1,2,3,4,5,6,7};
   GetBlock<word32, LittleEndian> block(buffer);
   block(w1)(w2);
