Constructor & Destructor Documentation

virtual input_uudecode::~input_uudecode

(

)

[virtual]

The destructor.

input_uudecode::input_uudecode

(

input &

deeper

)

The constructor.

Parameters:

deeper

The source of data for this filter.

input_uudecode::input_uudecode

(

)

[private]

The default constructor. Do not use.

input_uudecode::input_uudecode

(

const input_uudecode &

arg

)

[private]

The copy constructor. Do not use.

Member Function Documentation

nstring input_uudecode::name

(

)

[virtual]

The name method is used to determine the name of the input.

Implements input_ty.

long input_uudecode::length

(

)

[virtual]

The length method is used to determine the length of the input. May return -1 if the length is unknown.

Implements input_ty.

void input_uudecode::keepalive

(

)

[virtual]

The keepalive method is used to set the SO_KEEPALIVE socket option, if the file is a socket. Does nothing otherwise.

Reimplemented from input_ty.

long input_uudecode::read_inner	(	void *	data,
		size_t	nbytes
	)			[virtual]

The read_inner method is used to read unbuffered data from the given input stream. At most nbytes bytes will be read into data. The number of bytes actually read will be returned. At end-of-file, a value <= 0 will be returned, and data will be unchanged. All file read errors or format errors are fatal, and will cause the method to not return.

Parameters:

	data	Where to put the results of the read.
	nbytes	The maximum number of bytes to read.

Returns:

The actual number of bytes read, or zero for end-of-file.

Implements input_ty.

long input_uudecode::ftell_inner

(

)

[virtual]

The ftell_inner method is used to determine the unbuffered current position within the input.

Implements input_ty.

bool input_uudecode::is_remote

(

)

const [virtual]

The is_remote method is used to determine whether or not an input stream is from a local file or a remote source. This is only intended to be a generally informative thing, to provide information to the user, it isn't (and can't be) utterly precise.

Reimplemented from input_ty.

static bool input_uudecode::candidate

(

input &

deeper

)

[static]

The candidate class method is used to determine whether or not an input needs to be uudecoded. All input is pushed back, no matter what the result is.

input_uudecode& input_uudecode::operator=

(

const input_uudecode &

arg

)

[private]

The assignment operator. Do not use.
