Enum PythonREMode

java.lang.Enum<PythonREMode>

All Implemented Interfaces:

Serializable, Comparable<PythonREMode>

public enum PythonREMode
extends Enum<PythonREMode>

The enumeration of different flavors of Python regular expressions.

In Python, the standard regular expression engine behaves differently based on whether the pattern is a 'str' (string) or a 'bytes' (immutable byte buffer) object. Since all regexes are represented as Strings in TRegex, we cannot dispatch on the type of the pattern. Instead, we dispatch on values of this enumeration.
