AutoCloseable

@Name(value="tvm::runtime::InplaceArrayBase<tvm::runtime::ADTObj,tvm::runtime::ObjectRef>")
 @Properties(inherit=tvm_runtime.class)
public class ADTObjBase
extends Pointer

\brief Base template for classes with array like memory layout. It provides general methods to access the memory. The memory layout is ArrayType + [ElemType]. The alignment of ArrayType and ElemType is handled by the memory allocator. \tparam ArrayType The array header type, contains object specific metadata. \tparam ElemType The type of objects stored in the array right after ArrayType.

 // Example usage of the template to define a simple array wrapper
 class ArrayObj : public InplaceArrayBase<ArrayObj, Elem> {
 public:
  // Wrap EmplaceInit to initialize the elements
  template <typename Iterator>
  void Init(Iterator begin, Iterator end) {
   size_t num_elems = std::distance(begin, end);
   auto it = begin;
   this->size = 0;
   for (size_t i = 0; i < num_elems; ++i) {
     InplaceArrayBase::EmplaceInit(i, *it++);
     this->size++;
   }
  }
 }

 void test_function() {
   vector<Elem> fields;
   auto ptr = make_inplace_array_object<ArrayObj, Elem>(fields.size());
   ptr->Init(fields.begin(), fields.end());

   // Access the 0th element in the array.
   assert(ptr->operator[](0) == fields[0]);
 }
