JoinType (Jakarta EE Platform API)

java.lang.Object
- java.lang.Enum<JoinType>
- - jakarta.persistence.criteria.JoinType

All Implemented Interfaces:

Serializable, Comparable<JoinType>
```
public enum JoinType
extends Enum<JoinType>
```
Defines the three types of joins. Right outer joins and right outer fetch joins are not required to be supported. Applications that use RIGHT join types will not be portable.

Since:

2.0

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