ParserAttribute (CoffeeGrinder, Earley and GLL parsers in Java)

java.lang.Object
- org.nineml.coffeegrinder.util.ParserAttribute

```
public class ParserAttribute
extends java.lang.Object
```
Attributes that can be associated with a symbol or token.
ParserAttributes are a way to associate arbitrary additional information with the symbols in the grammar or the tokens in the input. For example, to associate additional metadata with nonterminals or to associate line and column numbers with tokens.

It's worth observing that the terminals created from the input stream don't get metadata.
