Detailed Description
The wide_output_to_narrow class represents the filtering necessary to convert a wide output stream into a narrow (multi-byte-char) output stream.Definition at line 31 of file to_narrow.h.
Constructor & Destructor Documentation
| virtual wide_output_to_narrow::~wide_output_to_narrow | ( | ) | [virtual] |
The destructor.
| wide_output_to_narrow::wide_output_to_narrow | ( | const output::pointer & | deeper | ) | [private] |
| wide_output_to_narrow::wide_output_to_narrow | ( | ) | [private] |
The default constructor. Do not use.
| wide_output_to_narrow::wide_output_to_narrow | ( | const wide_output_to_narrow & | ) | [private] |
The copy constructor. Do not use.
Member Function Documentation
| static pointer wide_output_to_narrow::open | ( | const output::pointer & | deeper | ) | [static] |
The open class method is used to create new dynamically alocated instances of this class.
- Parameters:
-
deeper where to write the filtered output
| nstring wide_output_to_narrow::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.
| int wide_output_to_narrow::page_width | ( | ) | [protected, virtual] |
The page-width method is used to obtain the width (in printing columns) of the output destination.
Implements wide_output.
| int wide_output_to_narrow::page_length | ( | ) | [protected, virtual] |
The length method is used to obtain the length (in whole lines) of the output destination.
Implements wide_output.
| const char* wide_output_to_narrow::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_to_narrow::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.
| void wide_output_to_narrow::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.
| void wide_output_to_narrow::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.
| wide_output_to_narrow& wide_output_to_narrow::operator= | ( | const wide_output_to_narrow & | ) | [private] |
The assignment operator. Do not use.
