Member Function Documentation

◆alloc()

virtual void* Vertica::VTAllocator::alloc(size_t size)

pure virtual Allocate size_t bytes of memory on a pool. This memory is guaranteed to persist beyond the destroy call but might have been destroyed when the dtor is run or freed explicitly.

◆free()

virtual void Vertica::VTAllocator::free(void * ptr, size_t size)

inlinevirtual

Free size_t bytes of memory allocated for ptr. Caution: safety is only guaranteed if free() is called on the same VTAllocator object that performed the alloc()
