Constructor & Destructor Documentation

sub_binary()

bsoncxx::v_noabi::builder::basic::sub_binary::sub_binary ( core * core )

inline

Default constructor.

Member Function Documentation

allocate() [1/2]

std::uint8_t * bsoncxx::v_noabi::builder::basic::sub_binary::allocate ( binary_sub_type sub_type, std::uint32_t length )

inline

Allocate space for an un-initialized BSON Binary element of any subtype.

Parameters

sub_type	BSON binary subtype code, identifying the format of the data within.
length	Number of bytes to allocate

Returns

Pointer to uninitialized memory within the bson_t, valid only during this sub_binary builder's lifetime. The caller must overwrite every byte if the resulting BSON document is to be used.

Exceptions

bsoncxx::v_noabi::exception	if this sub_binary has already allocated.
bsoncxx::v_noabi::exception	if the binary fails to append due to the BSON size limit.

allocate() [2/2]

template<typename Format, typename SFINAE = typename vector::detail::format_traits<Format>::value_type>

vector::accessor< Format > bsoncxx::v_noabi::builder::basic::sub_binary::allocate ( Format fmt, std::size_t element_count )

inline

Allocate and format space for a BSON Binary Vector with uninitialized elements.

Parameters

fmt	Instance of a format type from bsoncxx::v_noabi::vector::formats
element_count	Number of elements to allocate space for.

Returns

A writable vector::accessor, valid during the lifetime of this sub_binary builder. Every element must be overwritten before that element is read or the resulting document is used.

Exceptions

bsoncxx::v_noabi::exception	if this sub_binary has already allocated.
bsoncxx::v_noabi::exception	if the binary fails to append due to the BSON size limit.
bsoncxx::v_noabi::exception	if a vector of the requested size would be too large to represent.
