Enum Constants

TOP_LEVEL

public static final NestingKind TOP_LEVEL

A top-level type, not contained within another type.

MEMBER

public static final NestingKind MEMBER

A type that is a named member of another type.

LOCAL

public static final NestingKind LOCAL

A named type declared within a construct other than a type.

ANONYMOUS

public static final NestingKind ANONYMOUS

A type without a name.

Methods

values

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

Returns:

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

valueOf

public static NestingKind 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

isNested

public boolean isNested()

Does this constant correspond to a nested type element? A nested type element is any that is not top-level. An inner type element is any nested type element that is not static.

Returns:

whether or not the constant is nested
