Constructor & Destructor Documentation

virtual wide_output_unexpand::~wide_output_unexpand

(

)

[virtual]

The destructor.

wide_output_unexpand::wide_output_unexpand	(	const wide_output::pointer &	deeper,
		int	tabwidth
	)		[private]

The constructor. It is private on purpose, use the open class method instead.

Parameters:

deeper	where to write the filtered output
tabwidth	the column width of tab characters

wide_output_unexpand::wide_output_unexpand

(

)

[private]

The default constructor. Do not use.

wide_output_unexpand::wide_output_unexpand

(

const wide_output_unexpand &

)

[private]

The copy constructor. Do not use.

Member Function Documentation

void wide_output_unexpand::end_of_line_inner

(

)

[protected, virtual]

The end_of_line_inner method is used to do end-of-line processing by the derived class, if the buffered character state is not sufficient for the end_of_line method to determine whether or not the output position is currently at the start of a line.

Implements wide_output.

nstring wide_output_unexpand::filename

(

)

[protected, virtual]

The filename method is used to obtain the name of the file being written by this output stream.

Returns:

the name of the destination

Implements wide_output.

void wide_output_unexpand::flush_inner

(

)

[protected, virtual]

The flush_inner method is called by the flush method, after it writes any buffered data via the write_inner method.

Implements wide_output.

static pointer wide_output_unexpand::open	(	const wide_output::pointer &	deeper,
		int	tabwidth = 8
	)		[static]

The open class method is used to create new dynamically allocated instances of this class.

Parameters:

deeper	where to write the filtered output
tabwidth	the column width of tab characters

wide_output_unexpand& wide_output_unexpand::operator=

(

const wide_output_unexpand &

)

[private]

The assignment operator. Do not use.

int wide_output_unexpand::page_length

(

)

[protected, virtual]

The length method is used to obtain the length (in whole lines) of the output destination.

Implements wide_output.

int wide_output_unexpand::page_width

(

)

[protected, virtual]

The page-width method is used to obtain the width (in printing columns) of the output destination.

Implements wide_output.

const char* wide_output_unexpand::type_name

(

)

const [protected, virtual]

The type_name method is used to return the name of the class of output. Useful for debugging.

Implements wide_output.

void wide_output_unexpand::write_inner	(	const wchar_t *	data,
		size_t	len
	)		[protected, virtual]

The write_inner method is called by the write method to emit buffered data.

Parameters:

data	The data to be written
len	The number of wide characters to be written

Implements wide_output.
