Enum Constant Detail

CASE_INSENSITIVE

public static final Regex.Option CASE_INSENSITIVE

Enables case-insensitive matching.

FIXED_ENDER

public static final Regex.Option FIXED_ENDER

Creates a matcher for grammars where a fixed string ends the match. Examples are xml comments ending in --> or PCDATA ending in ]]>. Regular expression like '.\*\-\\->' without FIXED_ENDER option doesn't work. However with FIXED_ENDER option the underlying NFA is modified to support that kind of parsing before DFA creation. Note that the suffix is pushed back after recognition.

ACCEPT_IMMEDIATELY

public static final Regex.Option ACCEPT_IMMEDIATELY

Normally parser tries to match as more characters as is possible. For expression 'LITERAL|LITERALS' it accepts LITERALS for input LITERALS. if FIXED_ENDER options is used 'LITERAL' is matched instead without reading further input.

Method Detail

values

public static Regex.Option[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Regex.Option c : Regex.Option.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Regex.Option valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type has no constant with the specified name

NullPointerException - if the argument is null

supports

public static boolean supports(Regex.Option[] options,
               Regex.Option option)
