您可以在 C++/CX 程式中任意使用標準 C-Style 陣列或 std::array (雖然 std::vector 通常是比較好的選擇),但若是在中繼資料中所發行的任何 API 中,您必須根據 C-Style 陣列或向量的用途,將其轉換為 Platform::Array 或Platform::WriteOnlyArray 類型。 Platform::Array 類型的效率及功能都不如 std::vector...

前面的语句都是判断,知道最后的copy_array(s, src_pos, d, dst_pos, length, thread)是真正的copy,进一步看这里,在openjdk6-src/hotspot/src/share/vm/oops/typeArrayKlass.cpp中: voidtypeArrayKlass::copy_array(arrayOop s,intsrc_pos, arrayOop d,intdst_pos,intlength, TRAPS) { assert(s->is_ty...

Copy In the above example, we’ve created a single function template named passByRef() that has a parameter of type std::array<T, N>. T and N are defined in the template parameter declaration on the previous line: template <typename T, std::size_t N>. T is a standard type template...

voidCopy(constCArray& src); 参数 src 要复制到数组的元素的源。 备注 调用此成员函数以用另一个数组的元素覆盖一个数组的元素。 Copy不释放内存;但是,如有必要,Copy可能会分配额外的内存来容纳复制到数组的元素。 示例 C++ CArray<CPoint, CPoint> myArray1, myArray2;// Add elements to the second a...
