Enum TypeI.Nullability

java.lang.Object

java.lang.Enum<TypeI.Nullability>

com.google.javascript.rhino.TypeI.Nullability

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<TypeI.Nullability>

Enclosing interface:

TypeI

public static enum TypeI.Nullability
extends java.lang.Enum<TypeI.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 Summary

Enum Constants

Enum Constant and Description
EXPLICIT Include an explicit '!' for non-nullable reference types.
IMPLICIT Omit the explicit '!' from the outermost non-nullable reference type.

Method Summary

Modifier and Type	Method and Description
static TypeI.Nullability	valueOf(java.lang.String name) Returns the enum constant of this type with the specified name.
static TypeI.Nullability[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

EXPLICIT

public static final TypeI.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 TypeI.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 Detail

values

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

Returns:

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

valueOf

public static TypeI.Nullability valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
