Enum Class PythonREMode

java.lang.Object
java.lang.Enum<PythonREMode>

All Implemented Interfaces:
Serializable, Comparable<PythonREMode>, Constable
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.

  • Enum Constant Details

    • Str

      public static final PythonREMode Str
      String-based patterns, where the Python regular expression was given as a 'str' object.

    • Bytes

      public static final PythonREMode Bytes
      Bytes-based (binary) patterns, where the Python regular expression was given as a 'bytes' object.

  • Method Details

    • values

      public static PythonREMode[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static PythonREMode valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
