java.lang.Enum<OptionalBoolean>

com.kakao.util.OptionalBoolean

All Implemented Interfaces:

Serializable, Comparable<OptionalBoolean>

public enum OptionalBoolean
extends Enum<OptionalBoolean>

Enum class for representing nullable boolean values, usually in API responses. For example, the following API responses will translate to a variable (in a wrapper class) with enum type OptionalBoolean like below: {"has_email": true} = TRUE {"has_email": false} = FALSE {} = NONE

Represents true

Method Detail

getBoolean

public Boolean getBoolean()

getOptionalBoolean

public static OptionalBoolean getOptionalBoolean(Boolean bool)

valueOf

public static OptionalBoolean 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

values

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

Returns:

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