All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`Number`	`cast(Item item)`	Converts a structurally typed `item` into a nominally typed Java object.
`Item`	`mold(Number value)`	Converts a nominally typed Java `object` into its structurally typed equivalent.
`Class<Number>`	`type()`	Returns the reified `Class` of type `T`.
`Number`	`unit()`	Returns a default–possibly `null`–value of type `T`.

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

  - cast
```
public Number cast(Item item)
```
    Description copied from class: Form
