ValueForm (SwimOS)

java.lang.Object
- swim.structure.Form<Value>
- - swim.structure.form.ValueForm

```
public final class ValueForm
extends Form<Value>
```
Fall-through transformation between a structurally typed Item and a structurally typed Value. mold(swim.structure.Value) simply returns the Value argument itself, and cast(swim.structure.Item) simply invokes Item.toValue() against the Item argument.

Method Summary

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

public Value unit()
```
    Description copied from class: Form
    
    Returns a default–possibly null–value of type T. Used as the fallback return value when coercing an invalid structural value.
    
    Overrides:
    
    unit in class Form<Value>
  - unit
```
public Form<Value> unit(Value unit)
```
    Description copied from class: Form
    
    Returns a version of this Form with the given unit value.
    
    Overrides:
    
    unit in class Form<Value>
  - type
```
public Class<Value> type()
```
    Description copied from class: Form
    
    Returns the reified Class of type T.
    
    Specified by:
    
    type in class Form<Value>
  - mold
```
public Item mold(Value value)
```
    Description copied from class: Form
    
    Converts a nominally typed Java object into its structurally typed equivalent. The returned Item must never be null.
    
    Specified by:
    
    mold in class Form<Value>
  - cast
```
public Value cast(Item item)
```
    Description copied from class: Form
    
    Converts a structurally typed item into a nominally typed Java object. The passed-in item is assumed to be non-null.
    
    Specified by:
    
    cast in class Form<Value>
