| <h4><a class="xref" href="Lucene.Net.QueryParsers.Flexible.Standard.Parser.ICharStream.html">ICharStream</a></h4> |
| <section><p>This interface describes a character stream that maintains line and |
| column number positions of the characters. It also has the capability |
| to backup the stream to some extent. An implementation of this |
| interface is used in the TokenManager implementation generated by |
| JavaCCParser.</p> |
| <p>All the methods except <a class="xref" href="Lucene.Net.QueryParsers.Flexible.Standard.Parser.ICharStream.html#Lucene_Net_QueryParsers_Flexible_Standard_Parser_ICharStream_BackUp_System_Int32_">BackUp(Int32)</a> can be implemented in any fashion. <a class="xref" href="Lucene.Net.QueryParsers.Flexible.Standard.Parser.ICharStream.html#Lucene_Net_QueryParsers_Flexible_Standard_Parser_ICharStream_BackUp_System_Int32_">BackUp(Int32)</a> |
| needs to be implemented correctly for the correct operation of the lexer. |
| Rest of the methods are all used to get information like line number, |
| column number and the string that constitutes a token and are not used |
| by the lexer. Hence their implementation won't affect the generated lexer's |
| operation.</p> |
