- Method Detail
  - wrapAsCSet

public static <X> CSetSupplier<X> wrapAsCSet(SetSupplier setSupplier,
                                             java.util.function.Supplier<X> valueSupplier)
```
  - none
```
public static SetSupplier none()
```
    A supplier that supplies null instead of set instances. In nested structures such null values may act as placeholders that are replaced in a post-processing step.
    
    Returns:
    
    'null' casted to the appropriate type.
  - forceCast
```
public static SetSupplier forceCast(java.util.function.Supplier<Set<?>> setSupplier)
```
    Force cast to the requested type. Useful for e.g. TreeSets: While e.g. HashSet::new can supply set instances for any generic type, TreeSets are dependent on a comparator which may only work with specific types.
    
    Parameters:
    
    setSupplier -
    
    Returns:
  - forTreeSet
```
public static <X> SetSupplier forTreeSet(Comparator<X> cmp)
