Member Function Documentation

as_buffer()

template<class ALLOCATOR = legacy_allocator, typename CAPACITY_POLICY = default_capacity_policy>

buffer<ALLOCATOR, CAPACITY_POLICY> mdbx::to_base64::as_buffer ( const ALLOCATOR &  allocator = ALLOCATOR() ) const

inline

Returns a buffer with a Base64 dump of a passed slice.

as_string()

template<class ALLOCATOR = legacy_allocator>

string<ALLOCATOR> mdbx::to_base64::as_string ( const ALLOCATOR &  allocator = ALLOCATOR() ) const

inline

Returns a string with a Base64 dump of a passed slice.

envisage_result_length()

MDBX_CXX11_CONSTEXPR size_t mdbx::to_base64::envisage_result_length ( ) const

inlinenoexcept

Returns the buffer size in bytes needed for Base64 dump of passed slice.

is_empty()

bool mdbx::to_base64::is_empty ( ) const

inlinenoexcept

Checks whether a passed slice is empty, and therefore there will be no output bytes.

is_erroneous()

bool mdbx::to_base64::is_erroneous ( ) const

inlinenoexcept

Checks whether the content of a passed slice is a valid data and could be encoded or unexpectedly not.

output()

::std::ostream& mdbx::to_base64::output

(

::std::ostream &

out

)

const

Output Base64 dump of passed slice to the std::ostream.

Exceptions

std::ios_base::failure

corresponding to std::ostream::write() behaviour.

write_bytes()

char* mdbx::to_base64::write_bytes	(	char *	dest,
		size_t	dest_size
	)		const

Fills the buffer by Base64 dump of passed slice.

Exceptions

std::length_error

if given buffer is too small.
