ItemForm (SwimOS)

java.lang.Object
- swim.structure.Form<Item>
- - swim.structure.form.ItemForm

```
public final class ItemForm
extends Form<Item>
```
Fall-through "transformation" between a structural Item and a nominal Item. Both mold(swim.structure.Item) and cast(swim.structure.Item) simply return the Item argument itself.

public Form<Item> unit(Item unit)
```
    Description copied from class: Form
    
    Returns a version of this Form with the given unit value.

```
    Description copied from class: Form
    
    Returns the reified Class of type T.
    
    Specified by:

  - mold
```
public Item mold(Item item)
```
    Description copied from class: Form
    
    Converts a nominally typed Java object into its structurally typed equivalent. The returned Item must never be null.

    mold in class Form<Item>
  - cast
```
public Item cast(Item item)
```
    Description copied from class: Form
