Method AllocatedSize

tensorflow/core/framework/allocator.h:189–191

Returns the allocated size of the buffer at 'ptr' if known, otherwise returns RequestedSize(ptr). AllocatedSize(ptr) is guaranteed to be >= RequestedSize(ptr). REQUIRES: TracksAllocationSizes() is true. REQUIRES: 'ptr!=nullptr' and points to a buffer previously allocated by this allocator.

  // REQUIRES: 'ptr!=nullptr' and points to a buffer previously
  // allocated by this allocator.
  virtual size_t AllocatedSize(const void* ptr) const {
    return RequestedSize(ptr);
  }

  // Returns either 0 or an identifier assigned to the buffer at 'ptr'
  // when the buffer was returned by AllocateRaw. If non-zero, the
