When (Eagler Reborn API)

java.lang.Object
- java.lang.Enum<When>
- - javax.annotation.meta.When

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<When>
```
public enum When
extends java.lang.Enum<When>
```
Used to describe the relationship between a qualifier T and the set of values S possible on an annotated element. In particular, an issues should be reported if an ALWAYS or MAYBE value is used where a NEVER value is required, or if a NEVER or MAYBE value is used where an ALWAYS value is required.

Enum Constants
Enum Constant	Description
`ALWAYS`	S is a subset of T
`MAYBE`	S intersection T is non empty and S - T is nonempty
`NEVER`	S intersection T is empty
`UNKNOWN`	nothing definitive is known about the relation between S and T

```
public static When[] 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 (When c : When.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static When 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
