Public Member Functions | |
| Window (const iterator_t &stream, const iterator_t &eof, letter_t eol, length_t length) | |
| Standard constructor for the Window class. | |
| bool | eof () const |
| Indicates wether the end of the stream has been reached or not. | |
| bool | eol () const |
| Indicates wether a new line has been reached or not. | |
| void | shift (unsigned int n) |
| Shift the window. | |
| void | shift () |
| Shift the window completely (equivalent to shift (size ())). | |
| length_t | size () const |
| Returns the actual window size. | |
| letter_t | operator[] (length_t i) const |
| Returns the i-th character of the window. | |
| std::ostream & | print (std::ostream &ostr) const |
| Print the window. | |
| void | moveto (length_t offset) |
| Move to a specific offset. | |
| void | moveto (iterator_t position) |
| Move to a specific offset. | |
Accessors | |
| iterator_t | begin () const |
| Get an iterator to the beginning of the stream. | |
| iterator_t | stream () const |
| Get an iterator to the current position in the stream. | |
| iterator_t | end () const |
| Get an iterator to the end of the stream. | |
| size_t | offset () const |
| Get the actual offset in the stream. | |
| letter_t | eol_value () const |
| Get the letter value used for ending lines. | |
| length_t | length () const |
| Get the maximum length of the window. | |
| string_t | window () const |
Get the window as a basic_string<letter_t>. | |
Handle windows in streams for performing regular expression search.
A window is a portion of a stream, viewable as a string, on which several operations can be performed:
A window has a constant size, unless an end of line ('\n') or an end of file occurs, in which case a window is shorter than its supposed size.
| InputIterator | The type of input iterator used to read the stream. It shall be a random access iterator. | |
| Letter | The type used for letters. |
