Examples of org.contikios.cooja.mote.memory.SectionMoteMemory

org.contikios.cooja.mote.memory.SectionMoteMemory
Represents a mote memory consisting of non-overlapping memory sections with symbol addresses.
Every section must implement MemoyInterface.
Implements MemoryInterface by forwarding calls to available sections or returning an error if no section is available. @author Fredrik Osterlind @author Enrico Jorns
