Class ReferencePreprocessor

java.lang.Object
  net.sourceforge.nrl.parser.preprocessing.ReferencePreprocessor

public class ReferencePreprocessor
extends Object

The reference processor class detects fragment references, and resolves them before the main parsing stage.

It scans the rule file for fragment declarations, and then for any sentence fragments that equal the fragment declaration. If it finds any, it puts the curly brackets that the parser expects around them.

For example, if "this is a fragment" is declared as a fragment somewhere and the text this is a fragment is detected in the rule file, it has curly brackets placed around it.
