calcDigest()

digidoc::DataFile::calcDigest ( const std::string &  method ) const

pure virtual

Calculates digest for data file. If digest is already calculated returns it, otherwise calculates the digest.

Supported uris:

• http://www.w3.org/2000/09/xmldsig#sha1
• http://www.w3.org/2001/04/xmldsig-more#sha224
• http://www.w3.org/2001/04/xmlenc#sha256
• http://www.w3.org/2001/04/xmldsig-more#sha384
• http://www.w3.org/2001/04/xmlenc#sha512

In case of DDoc files, the parameter is ignored and SHA1 hash is always returned

Parameters

method

method uri for calculating digest.

Returns

returns calculated digest.

Exceptions

Exception

throws exception if the file does not exist or digest calculation fails.

fileName()

digidoc::DataFile::fileName ( ) const

pure virtual

Returns data file name

fileSize()

digidoc::DataFile::fileSize ( ) const

pure virtual

Returns data file size

id()

digidoc::DataFile::id ( ) const

pure virtual

Returns data file id

mediaType()

digidoc::DataFile::mediaType ( ) const

pure virtual

Returns data file's media type

saveAs() [1/2]

void digidoc::DataFile::saveAs ( const std::string &  path ) const

pure virtual

Saves a copy of the data file as file specified by path.

Parameters

path	full file path, where the data file should be saved to. If file exists, it is overwritten

Exceptions

Exception

if part of path does not exist or path is existing directory (without file name)

saveAs() [2/2]

void digidoc::DataFile::saveAs ( std::ostream &  os ) const

pure virtual

Saves a copy of the data file as file specified by stream.

Parameters

os	stream where data is written
