Enum Constant Detail

LOWER_HYPHEN

public static final CaseFormat LOWER_HYPHEN

Hyphenated variable naming convention, e.g., "lower-hyphen".

LOWER_UNDERSCORE

public static final CaseFormat LOWER_UNDERSCORE

C++ variable naming convention, e.g., "lower_underscore".

LOWER_CAMEL

public static final CaseFormat LOWER_CAMEL

Java variable naming convention, e.g., "lowerCamel".

UPPER_CAMEL

public static final CaseFormat UPPER_CAMEL

Java and C++ class naming convention, e.g., "UpperCamel".

UPPER_UNDERSCORE

public static final CaseFormat UPPER_UNDERSCORE

Java and C++ constant naming convention, e.g., "UPPER_UNDERSCORE".

Method Detail

values

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

Returns:

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

valueOf

public static CaseFormat 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

to

public final String to(CaseFormat format,
        String str)

Converts the specified String str from this format to the specified format. A "best effort" approach is taken; if str does not conform to the assumed format, then the behavior of this method is undefined but we make a reasonable effort at converting anyway.

converterTo

@Beta
public Converter<String,String> converterTo(CaseFormat targetFormat)

Returns a Converter that converts strings from this format to targetFormat.
