Enum Constant Summary

Enum Constants
Enum Constant and Description
`AUTO` The automatic lock mode will use optimistic locking if possible or no locking.
`NONE` No locking at any point is done.
`OPTIMISTIC` The optimistic locking mode will use the version attribute of an entity to for optimistic locking.
`PESSIMISTIC_READ` The pessimistic read locking mode will acquire a `LockModeType.PESSIMISTIC_READ` for the entity when reading the entity view.
`PESSIMISTIC_WRITE` The pessimistic write locking mode will acquire a `LockModeType.PESSIMISTIC_WRITE` for the entity when reading the entity view.

- Enum Constant Detail
  - AUTO
```
public static final LockMode AUTO
```
    The automatic lock mode will use optimistic locking if possible or no locking.
  - OPTIMISTIC
```
public static final LockMode OPTIMISTIC
```
    The optimistic locking mode will use the version attribute of an entity to for optimistic locking.
  - PESSIMISTIC_READ
```
public static final LockMode PESSIMISTIC_READ
```
    The pessimistic read locking mode will acquire a LockModeType.PESSIMISTIC_READ for the entity when reading the entity view. This lock mode is only useful within the bounds of a single transaction as the lock is bound to it.
  - PESSIMISTIC_WRITE
```
public static final LockMode PESSIMISTIC_WRITE
```
    The pessimistic write locking mode will acquire a LockModeType.PESSIMISTIC_WRITE for the entity when reading the entity view. This lock mode is only useful within the bounds of a single transaction as the lock is bound to it.
  - NONE
```
public static final LockMode NONE
```
    No locking at any point is done.
- Method Detail
  - values
```
public static LockMode[] 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 (LockMode c : LockMode.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static LockMode 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
