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> . |
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. |
