Assignment (Digipost Digg 0.31 API)

Type Parameters:

V - The type that may be assigned (or not).

All Superinterfaces:

Consumer<V>, Supplier<V>, ViewableAsOptional<V>, ViewableAsOptional.Single<V>

All Known Implementing Classes:

ChainableAssignment, OneTimeAssignment
```
public interface Assignment<V>
extends Supplier<V>, Consumer<V>, ViewableAsOptional.Single<V>
```
An assignment may or may not be assigned, the assigned value can be retrieved with Supplier.get() and will return null if unassigned, and may be assigned with set(Object) if the assignment allows (re-)assignment.

- Method Detail
  - from
```
static <V> Assignment<V> from(AtomicReference<V> reference)
```
    Create a new Assignment which uses an AtomicReference to hold the assigned value.
    
    Parameters:
    
    reference - the holder of the assigned value
    
    Returns:
    
    the new Assignment using the given AtomicReference.
  - from
```
static <V,S> Assignment<V> from(S container,
                                      Function<? super S,V> getter,
                                      BiConsumer<? super S,? super V> setter)
```
    Create a new Assignment, which assigns to and retrieves from an arbitrary container object.
    
    Parameters:
    
    container - The holder of the assigned value.
    
    getter - how the get the value from the container
    
    setter - how to set the value on the container
    
    Returns:
    
    the get and set operations as a new Assignment.
  - set
```
void set(V value)
```
    Assign the given value.
    
    Parameters:
    
    value - the value to assign.
  - accept
```
default void accept(V value)
```
    Specified by:
    
    accept in interface Consumer<V>
  - chainableWith
```
default <C> ChainableAssignment<V,C> chainableWith(C chainReturnObject)
```
    Create a ChainableAssignment from this assignment.
