Detailed Description
The wide_output_expand class is used to replace tabs with spaces. This simplifies a lot of the internal width calculations for things like truncating, wrapping and reassembling. This internal filtering uses 8-character tabs; the -tw option is exclusively for output tab widths.
Constructor & Destructor Documentation
| virtual wide_output_expand::~wide_output_expand | ( | ) | [virtual] |
The destructor.
| wide_output_expand::wide_output_expand | ( | const wide_output::pointer & | deeper | ) | [private] |
The constructor. It is private on purpose, use the open class method instead.
- Parameters:
-
deeper when to send the expanded output
| wide_output_expand::wide_output_expand | ( | ) | [private] |
The default constructor. Do not use.
| wide_output_expand::wide_output_expand | ( | const wide_output_expand & | ) | [private] |
The copy constructor. Do not use.
Member Function Documentation
| void wide_output_expand::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_expand::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_expand::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_expand::open | ( | const wide_output::pointer & | deeper | ) | [static] |
The open class method is sued to create new dynamically allocated instances of this class.
- Parameters:
-
deeper when to send the expanded output
| wide_output_expand& wide_output_expand::operator= | ( | const wide_output_expand & | ) | [private] |
The assignment operator. Do not use.
| int wide_output_expand::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_expand::page_width | ( | ) | [protected, virtual] |
The page-width method is used to obtain the width (in printing columns) of the output destination.
Implements wide_output.
| void wide_output_expand::put_hex | ( | int | n | ) | [private] |
| const char* wide_output_expand::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_expand::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.
