Public Member Functions
virtual std::size_t	size () const noexcept=0
	Returns the payload size in bytes.
virtual void	Read (std::size_t offset, void *dst, std::size_t size) const =0
	Copies size bytes starting at offset into dst.
virtual void	WriteTo (std::ostream &dst) const =0
	Writes the whole payload to dst without materializing a copy.

Detailed Description

Read-only source for an attachment payload.

A source owns or shares the (already decrypted) bytes and exposes them without forcing the object model to materialize a per-attachment copy. The KDBX 4 importer stores all inner-header binaries in one shared, zeroized buffer and creates a small source view for each attachment.

Member Function Documentation

Read()

virtual void keepass::detail::BinarySource::Read ( std::size_t  offset, void *  dst, std::size_t  size  ) const

pure virtual

Copies size bytes starting at offset into dst.

Exceptions

IoError

if the requested range is outside the source.

Implemented in keepass::detail::BufferBinarySource.

size()

virtual std::size_t keepass::detail::BinarySource::size ( ) const

pure virtualnoexcept

Returns the payload size in bytes.

Implemented in keepass::detail::BufferBinarySource.

WriteTo()

virtual void keepass::detail::BinarySource::WriteTo ( std::ostream &  dst ) const

pure virtual

Writes the whole payload to dst without materializing a copy.

Exceptions

IoError

on write failure.

Implemented in keepass::detail::BufferBinarySource.
