harpoon.Analysis.Realtime
Class RealtimeAllocationStrategy

java.lang.Object
  harpoon.Backend.Runtime1.AllocationStrategy
      harpoon.Backend.Runtime1.MallocAllocationStrategy
          harpoon.Analysis.Realtime.RealtimeAllocationStrategy

All Implemented Interfaces:

Serializable

public class RealtimeAllocationStrategy
extends MallocAllocationStrategy

RealtimeAllocationStrategy makes all memory allocations to go through RTJ_malloc. If DEBUG_REF is turned on, then it calls RTJ_malloc_ref(size, fileNumber, "fileName"). The const char* "fileName" must be emitted in a separate area, so emitStrings must be called later in the file to emit that data.
