Enum Constant Detail

IGNORE_NULL

public static final Strings.NullConcatenation IGNORE_NULL

Null values in concatenation are ignored. Effectively, nulls are treated as the empty string.

YIELD_NULL

public static final Strings.NullConcatenation YIELD_NULL

Null values in concatenation make the result null

Method Detail

values

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

Returns:

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

valueOf

public static Strings.NullConcatenation 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
