A read-only BSON array that owns its underlying buffer.
When a array::value goes out of scope, the underlying buffer is freed. Generally this class should be used sparingly; array::view should be used instead wherever possible.
bsoncxx::v_noabi::array::value::value | ( | std::uint8_t * | data, |
std::size_t | length, | ||
deleter_type | dtor | ||
) |
Constructs a value from a buffer.
This constructor transfers ownership of the buffer to the resulting value. A user-provided deleter is used to destroy the buffer.
data | A pointer to a buffer containing a valid BSON array. |
length | The length of the document. |
dtor | A user provided deleter. |
bsoncxx::v_noabi::array::value::value | ( | unique_ptr_type | ptr, |
std::size_t | length | ||
) |
Constructs a value from a std::unique_ptr to a buffer.
The ownership of the buffer is transferred to the resulting value.
ptr | A pointer to a buffer containing a valid BSON array. |
length | The length of the document. |
|
explicit |
Constructs a value from a view of an array.
The data referenced by the array::view will be copied into a new buffer managed by the constructed value.
view | A view of another array to copy. |
|
noexcept |
Conversion operator that provides a view given a value.
unique_ptr_type bsoncxx::v_noabi::array::value::release | ( | ) |
Transfer ownership of the underlying buffer to the caller.
