public final class RegexResult
extends AbstractConstantKeysObject

RegexResult is a TruffleObject that represents the result of matching a regular expression against a string. It can be obtained as the result of a RegexObject's exec method and has the following properties:

1. boolean isMatch: true if a match was found, false otherwise.
2. TruffleObject getStart(int groupNumber): returns the position where the beginning of the capture group with the given number was found. If the result is no match, the returned value is undefined. Capture group number 0 denotes the boundaries of the entire expression. If no match was found for a particular capture group, the returned value is -1.
3. TruffleObject end: returns the position where the end of the capture group with the given number was found. If the result is no match, the returned value is undefined. Capture group number 0 denotes the boundaries of the entire expression. If no match was found for a particular capture group, the returned value is -1.
4. int lastGroup: The index of the last capture group that was matched. -1 if no capture group was matched. This property is only tracked for Python regular expressions. For other flavors of regular expressions, this always has the value -1.
