Adds the AfterNewline method to SourceFile. More...
Adds the AfterNewline method to SourceFile.
When implementing a lexer, the most efficient approach to building the list of line breaks is to save the location of each newline as it is encountered while lexing, rather than doing a separate pass over the file just to find line breaks. This class supports this optimization.

Allows a lexer to record the index of the character after each line break, in the order they exist in the file or string.
| index | Index of the first character after the newline. |
A lexer is not required to call this method; if the lexer doesn't call it, the list of line breaks (which is used to map indexes to line numbers and vice versa) will be built on-demand when one calls methods such as IndexToLine.
