## javax.persistence.criteria
Enum JoinType

    java.lang.Object
      java.lang.Enum<JoinType>
          javax.persistence.criteria.JoinType

All Implemented Interfaces:
  java.io.Serializable, java.lang.Comparable<JoinType>

    public enum JoinType

extends java.lang.Enum<JoinType>

Defines the three types of joins. Right outer joins and right outer fetch joins are not required to be supported in Java Persistence 2.0. Applications that use `RIGHT` join types will not be portable.

Since:
  Java Persistence 2.0

Enum Constant Summary
`INNER` Inner join.
`LEFT` Left outer join.
`RIGHT` Right outer join.

Method Summary
`static JoinType` | `valueOf(java.lang.String name)` Returns the enum constant of this type with the specified name.
`static JoinType[]` | `values()` Returns an array containing the constants of this enum type, in the order they are declared.

Methods inherited from class java.lang.Enum
`compareTo, equals, getDeclaringClass, hashCode, name, ordinal, toString, valueOf`

Methods inherited from class java.lang.Object
`getClass, notify, notifyAll, wait, wait, wait`

Enum Constant Detail

### INNER

    public static final JoinType INNER

  Inner join.

### LEFT

    public static final JoinType LEFT

  Left outer join.

### RIGHT

    public static final JoinType RIGHT

  Right outer join.

Method Detail

### values

    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(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
