Class SelfScoredOracle

java.lang.Object

edu.odu.cs.zeil.codegrader.oracle.Oracle

edu.odu.cs.zeil.codegrader.oracle.SelfScoredOracle

public class SelfScoredOracle
extends Oracle

An oracle that scans the output for the score. Each line is matched against a pattern that must supply a named capturing group "pts" and, optionally, a named capturing group "poss". If the pattern provides only pts, the match is considered to be the score. If the pattern provides both pts and poss, the score is 100*pts/poss. The patten is applied to each line of the out. It can match a substring of that line. The last line of observed output containing a match to the pattern is the one that is used.
