Examples of xtc.parser.Result.createValue()

xtc.parser.Result.createValue()
Create a semantic value based on this result. A straight-forward implementation of this method simply creates a new semantic value, using the specified actual value, this result's index, and the specified parse error:
```
 public SemanticValue value(Object value, ParseError error) { return new SemanticValue(value, index, error); } 
```
However, for a result that already is a semantic value, a more sophisticated implementation can avoid creating a new semantic value if the specified actual value and parse error are identical to those for this result. @param value The actual value. @param error The embedded parse error. @throws IllegalStateException Signals that this result is aparse error.
