Enum Constant Summary

Enum Constants

Enum Constant	Description
AUTO	Produce native sealed classes when compiling for a suitable target bytecode (JDK17+) and automatically emulate the concept on earlier JDKs.
EMULATE	Indicate the sealed nature using annotations.
NATIVE	Produce Java-like code with sealed nature indicated by "native" bytecode information (JEP 360/397/409).

Method Summary

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

Enum Constant Details

EMULATE

public static final SealedMode EMULATE

Indicate the sealed nature using annotations. This allows sealed hierarchies in earlier JDKs but for integration purposes won't be recognised by Java.

NATIVE

public static final SealedMode NATIVE

Produce Java-like code with sealed nature indicated by "native" bytecode information (JEP 360/397/409). Produces a compile-time error when used on earlier JDKs.

AUTO

public static final SealedMode AUTO

Produce native sealed classes when compiling for a suitable target bytecode (JDK17+) and automatically emulate the concept on earlier JDKs.

Method Details

values

public static SealedMode[] values()

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

Returns:

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

valueOf

public static SealedMode 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
