Member Function Documentation

as_buffer()

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

buffer<ALLOCATOR, CAPACITY_POLICY> mdbx::from_base64::as_buffer ( const ALLOCATOR &  allocator = ALLOCATOR() ) const

inline

Decodes Base64 dump from a passed slice to returned buffer.

as_string()

template<class ALLOCATOR = legacy_allocator>

string<ALLOCATOR> mdbx::from_base64::as_string ( const ALLOCATOR &  allocator = ALLOCATOR() ) const

inline

Decodes Base64 dump from a passed slice to returned string.

envisage_result_length()

MDBX_CXX11_CONSTEXPR size_t mdbx::from_base64::envisage_result_length ( ) const

inlinenoexcept

Returns the number of bytes needed for conversion Base64 dump from a passed slice to decoded data.

is_empty()

bool mdbx::from_base64::is_empty ( ) const

inlinenoexcept

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

is_erroneous()

bool mdbx::from_base64::is_erroneous ( ) const

noexcept

Checks whether the content of a passed slice is a valid Base64 dump, and therefore there could be decoded or not.

write_bytes()

char* mdbx::from_base64::write_bytes	(	char *	dest,
		size_t	dest_size
	)		const

Fills the destination with data decoded from Base64 dump from a passed slice.

Exceptions

std::length_error

if given buffer is too small.
