First of all, I have started implementation, and a part of
implementation is completed.
For your question, I can explain it as follows:
Example I have 3 memory blocks.
Memory block 1: Ptr = 0x1000, Len = 100
Memory block 2: Ptr = 0x2000, Len = 5
Memory block 3: Ptr = 0x3000, Len = 150
Into the class FragmentedMemory, you append those three memory
blocks. Then it provides you an interface like those three memory
blocks are consecutive.
Let's say: fragmem[ 125 ] = 5;
Because the index 125 is in memory block 3, the value is written
to memoryBlock3[ 20 ];
(125 = 100 + 5 + 20 )
Reading is in the same way. I think you can think about use cases
on your side.
Currently, set, get, append operations are completed.
I will implement bulk memory copy and assign operations as well.
