Constructor & Destructor Documentation

Arguments() [1/2]

Arguments::Arguments ( void  )

inline

Arguments() [2/2]

Arguments::Arguments	(	int	argc,
		char *	argv[]
	)

initialize this Arguments object with argc and argv

Member Function Documentation

getPassphrase()

std::string Arguments::getPassphrase

(

bool

doublecheck = false

)

parse()

void Arguments::parse

(

void

)

parse Argc and Argv filling the Arg* member variable for later access

parse_Checksum()

bool Arguments::parse_Checksum ( ArgIt &  curarg )

private

parse_Command()

void Arguments::parse_Command ( ArgIt &  curarg )

private

parse the command

Note: parse_Command is the only parse_* function that requires curarg to be a command. (because the command is the only argument with a fixed position).

parse_Compression()

bool Arguments::parse_Compression ( ArgIt &  curarg )

private

parse_CvrFn()

bool Arguments::parse_CvrFn ( ArgIt &  curarg )

private

parse_Debug()

bool Arguments::parse_Debug ( ArgIt &  curarg )

private

parse_EmbedEmbFn()

bool Arguments::parse_EmbedEmbFn ( ArgIt &  curarg )

private

parse_EmbFn()

bool Arguments::parse_EmbFn ( ArgIt &  curarg )

private

test if curarg points to an emb filename argument and if yes: parse it

Returns

true iff one or more arguments have been parsed

parse_Encryption()

bool Arguments::parse_Encryption ( ArgIt &  curarg )

private

parse_ExtFn()

bool Arguments::parse_ExtFn ( ArgIt &  curarg )

private

parse_Force()

bool Arguments::parse_Force ( ArgIt &  curarg )

private

parse_Goal()

bool Arguments::parse_Goal ( ArgIt &  curarg )

private

parse_Passphrase()

private

setDefaults()

void Arguments::setDefaults ( void  )

private

stdin_isused()

bool Arguments::stdin_isused

(

void

)

const

is standard input used ? - according to the given arguments
