Detailed Description

the output_tee class is used to represent an output filter which writes its output to two places at once.

Definition at line 28 of file tee.h.

Constructor & Destructor Documentation

virtual output_tee::~output_tee

(

)

[virtual]

The destructor.

output_tee::output_tee	(	const output::pointer &	d1,
		const output::pointer &	d2
	)		[private]

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

Parameters:

d1	the deeper output stream on which this filter writes to.
d2	the deeper output stream on which this filter writes to.

output_tee::output_tee

(

)

[private]

The default constructor. Do not use.

output_tee::output_tee

(

const output_tee &

)

[private]

The copy constructor. Do not use.

Member Function Documentation

static pointer output_tee::create	(	const output::pointer &	d1,
		const output::pointer &	d2
	)		[static]

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

Parameters:

d1	the deeper output stream on which this filter writes to.
d2	the deeper output stream on which this filter writes to.

void output_tee::end_of_line_inner

(

void

)

[protected, virtual]

The end_of_line_inner method is used to ensure that the current output position is at the beginning of a line, without taking the buffering into account.

Implements output.

nstring output_tee::filename

(

void

)

const [protected, virtual]

The filename method is used to obtain the filename of this output.

Implements output.

void output_tee::flush_inner

(

void

)

[protected, virtual]

The flush_inner method is called by the flush method once all the data has been written. The default implementation does nothing.

Reimplemented from output.

long output_tee::ftell_inner

(

void

)

const [protected, virtual]

The ftell_inner method is used to determine the current file position, without taking the buffering into account.

Implements output.

output_tee& output_tee::operator=

(

const output_tee &

)

[private]

The assignment operator. Do not use.

int output_tee::page_length

(

void

)

const [protected, virtual]

The page_length method is used to obtain the length of the page of the output device.

Reimplemented from output.

int output_tee::page_width

(

void

)

const [protected, virtual]

The page_width method is used to obtain the width of the page of the output device.

Reimplemented from output.

nstring output_tee::type_name

(

void

)

const [protected, virtual]

The type_name method is used to determine the name of this output device or file or type.

Implements output.

void output_tee::write_inner	(	const void *	data,
		size_t	length
	)		[protected, virtual]

The write_inner method is used write data to the output, without taking the buffering into account.

Implements output.

Field Documentation

output::pointer output_tee::d1 [private]

The d1 instance variable is used to remember the deeper output stream on which this filter writes to.

Definition at line 91 of file tee.h.

bool output_tee::d1_close [private]

The d1_close instance variable is used to remember whether or not the d1 output stream is to be deleted in our destructor.

Definition at line 97 of file tee.h.

output::pointer output_tee::d2 [private]

The d2 instance variable is used to remember the deeper output stream on which this filter writes to.

Definition at line 103 of file tee.h.

bool output_tee::d2_close [private]

The d2_close instance variable is used to remember whether or not the d2 output stream is to be deleted in our destructor.

Definition at line 109 of file tee.h.
