/**
 * INTERNAL:
 * An implementation of in memory queries with Like which uses the
 * regular expression framework.
 */
public static Boolean conformLike(Object left, Object right) {
  if ((left == null) && (right == null)) {
    return Boolean.TRUE;
  } else if ((left == null) || (right == null)) {
    return Boolean.FALSE;
  }
  left = String.valueOf(left);
  right = String.valueOf(right);
  // PERF: First check the pattern cache for the pattern.
  // Note that the original string is the key, to avoid having to translate it first.
  Pattern pattern = (Pattern)patternCache.get(right);
  if (pattern == null) {
    // Bug 3936427 - Replace regular expression reserved characters with escaped version of those characters
    // For instance replace ? with \?
    String convertedRight = Helper.convertLikeToRegex((String)right);
    pattern = Pattern.compile(convertedRight);
    // Ensure cache does not grow beyond 100.
    if (patternCache.size() > 100) {
      patternCache.remove(patternCache.keySet().iterator().next());
    }
    patternCache.put(right, pattern);
  }
  return pattern.matcher((String)left).matches();
}
