Enum Class JSType.Nullability

java.lang.Object

java.lang.Enum<JSType.Nullability>

com.google.javascript.rhino.jstype.JSType.Nullability

All Implemented Interfaces:

Serializable, Comparable<JSType.Nullability>, Constable

Enclosing class:

JSType

public static enum JSType.Nullability
extends Enum<JSType.Nullability>

Specifies how to express nullability of reference types in annotation strings and error messages. Note that this only applies to the outer-most type. Nullability of generic type arguments is always explicit.

Enum Constant Details

EXPLICIT

public static final JSType.Nullability EXPLICIT

Include an explicit '!' for non-nullable reference types. This is suitable for use in most type contexts (particularly 'type', 'param', and 'return' annotations).

IMPLICIT

public static final JSType.Nullability IMPLICIT

Omit the explicit '!' from the outermost non-nullable reference type. This is suitable for use in cases where a single reference type is expected (e.g. 'extends' and 'implements').

Method Details

values

public static JSType.Nullability[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static JSType.Nullability valueOf(String name)

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

NullPointerException - if the argument is null
