Method Detail

values

public static RegexNFATypeEnum[] 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 (RegexNFATypeEnum c : RegexNFATypeEnum.values())
    System.out.println(c);

Returns:

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

valueOf

public static RegexNFATypeEnum 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

public boolean isMultipleMatches()

Returns indicator if single or multiple matches.

Returns:

indicator

isOptional

public boolean isOptional()

Returns indicator if optional matches.

Returns:

indicator

isGreedy

public Boolean isGreedy()

Returns indicator if greedy or reluctant.

Returns:

indicator

fromString
