Member Function Documentation

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.

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()
