Java Source Code / Java Documentation » Parser » Rats Parser Generators » xtc.parser   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    xtc.tree.Visitor       xtc.parser.CostEstimator CostEstimator public class CostEstimator extends Visitor (Code) Visitor to provide a conservative estimate for the cost of parsing a production. One unit of cost is approximately equivalent to the effort involved in parsing a character and testing it for a specific value. The cost estimate for a production includes the costs for any other productions referenced by that production. If the cost cannot be statically determined (for example, for a repetition) or a set of productions is mutually recursive, the cost is assumed to be unlimited, as represented by Integer.MAX_VALUE. This visitor must be invoked by visiting a grammar, which clears any previous cost estimates and annotates each production with its estimated cost. This visitor assumes that the entire grammar is contained in a single module. author:    Robert Grimm version:    $Revision: 1.26 $ Field Summary final protected  Analyzer analyzer      The analyzer utility.
