Detailed Description

Wraps an archive around a binary filestream for input.

Constructor & Destructor Documentation

BinaryFstreamInputArchive() [1/2]

madness::archive::BinaryFstreamInputArchive::BinaryFstreamInputArchive	(	const char *	filename = nullptr,
		std::ios_base::openmode	mode = std::ios_base::binary | std::ios_base::in
	)

Default constructor.

The filename and open modes are optional here; they can be specified later by calling open().

Parameters

[in]	filename	Name of the file to read from.
[in]	mode	I/O attributes for opening the file.

References madness::filename, and open().

BinaryFstreamInputArchive() [2/2]

madness::archive::BinaryFstreamInputArchive::BinaryFstreamInputArchive ( const std::string  name, std::ios_base::openmode  mode = std::ios_base::binary | std::ios_base::in  )

inline

Default constructor.

The filename and open modes are optional here; they can be specified later by calling open().

Parameters

[in]	filename	Name of the file to read from.
[in]	mode	I/O attributes for opening the file.

Member Function Documentation

close()

void madness::archive::BinaryFstreamInputArchive::close

(

)

Close the filestream.

References iobuf, and is.

Referenced by main().

load()

template<class T >

std::enable_if< is_trivially_serializable< T >::value, void >::type madness::archive::BinaryFstreamInputArchive::load ( T *  t, long  n  ) const

inline

Load from the filestream.

The function only appears (due to enable_if) if T is serializable.

Template Parameters

T	The type of data to be read.

Parameters

[out]	t	Where to put the loaded data.
[in]	n	The number of data items to be loaded.

References is, and T().

open()

void madness::archive::BinaryFstreamInputArchive::open	(	const char *	filename,
		std::ios_base::openmode	mode = std::ios_base::binary | std::ios_base::in
	)

Open the filestream.

Parameters

[in]	filename	Name of the file to read from.
[in]	mode	I/O attributes for opening the file.
