Enum Constant Summary

Enum Constants

Enum Constant	Description
IMPLICIT	Discover the type when no ambiguity is present if neither on a method nor a constructor, it implies the annotated element (type, field etc), if on a method or constructor with no parameter, it implies RETURN_VALUE, if on a method with no return value (void), it implies PARAMETERS. Otherwise, IMPLICIT is not accepted and either RETURN_VALUE or PARAMETERS is required.
PARAMETERS	Constraint applies to the parameters of a method or a constructor
RETURN_VALUE	Constraint applies to the return value of a method or a constructor.

Method Summary

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

Enum Constant Details

IMPLICIT

public static final ConstraintTarget IMPLICIT

Discover the type when no ambiguity is present

• if neither on a method nor a constructor, it implies the annotated element (type, field etc),
• if on a method or constructor with no parameter, it implies RETURN_VALUE,
• if on a method with no return value (void), it implies PARAMETERS.

Otherwise, IMPLICIT is not accepted and either RETURN_VALUE or PARAMETERS is required. This is the case for constructors with parameters and methods with parameters and return value.

RETURN_VALUE

public static final ConstraintTarget RETURN_VALUE

Constraint applies to the return value of a method or a constructor.

PARAMETERS

public static final ConstraintTarget PARAMETERS

Constraint applies to the parameters of a method or a constructor

Method Details

values

public static ConstraintTarget[] 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 ConstraintTarget 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
