class
AllocationTracker
: public umpire::strategy::AllocationStrategy, umpire::strategy::mixins::Inspector¶ Public Functions
-
void *
allocate
(size_t bytes)¶ Allocate bytes of memory.
- Return
- Pointer to start of allocated bytes.
- Parameters
bytes
: Number of bytes to allocate.
-
void
deallocate
(void *ptr)¶ Free the memory at ptr.
- Parameters
ptr
: Pointer to free.
-
void
release
()¶ Release any and all unused memory held by this AllocationStrategy.
-
long
getCurrentSize
() const¶ Get current (total) size of the allocated memory.
This is the total size of all allocation currently ‘live’ that have been made by this AllocationStrategy object.
- Return
- Current total size of allocations.
-
long
getHighWatermark
() const¶ Get the high watermark of the total allocated size.
This is equivalent to the highest observed value of getCurrentSize.
- Return
- High watermark allocation size.
-
long
getActualSize
() const¶ Get the current amount of memory allocated by this allocator.
Note that this can be larger than getCurrentSize(), particularly if the AllocationStrategy implements some kind of pooling.
- Return
- The total size of all the memory this object has allocated.
-
Platform
getPlatform
()¶ Get the platform associated with this AllocationStrategy.
The Platform distinguishes the appropriate place to execute operations on memory allocated by this AllocationStrategy.
- Return
- The platform associated with this AllocationStrategy.
-

const std::string &
getName
() Get the name of this AllocationStrategy.
- Return
- The name of this AllocationStrategy.
-
int
