Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`boolean`	`booleanValue()`	Always returns `true` because `Extant` behaves like a truthy value.
`boolean`	`booleanValue(boolean orElse)`	Always returns `true` because `Extant` behaves like a truthy value.
`int`	`compareTo(Item other)`
`<T> Output<T>`	`debug(Output<T> output)`	Writes a developer readable, debug-formatted string representation of this object to `output`.
`boolean`	`equals(Object other)`
`static Extant`	`extant()`
`int`	`hashCode()`
`boolean`	`isConstant()`	Returns `true` if this `Item` always `evaluates` to the same `Item`.
`boolean`	`isDefined()`	Always returns `true` because `Extant` is a defined value.
`boolean`	`isDefinite()`	Always returns `false` because `Extant` is not a definite value.
`boolean`	`isDistinct()`	Always returns `false` because `Extant` is not a distinct value.
`Value`	`not()`
`String`	`stringValue()`	Always returns the empty `String` because `Extant` behaves like an empty `Record`, which converts to a `String` by concatenating the string values of all its members, if all its members convert to string values.
`String`	`stringValue(String orElse)`	Always returns the empty `String` because `Extant` behaves like an empty `Record`, which converts to a `String` by concatenating the string values of all its members, if all its members convert to string values.
`int`	`typeOrder()`	Returns the heterogeneous sort order of this `Item`.
`Record`	`unflattened()`	Always returns an empty `Record` because `Extant` is not a distinct value.

- Method Detail
  - isDefined
```
public boolean isDefined()
```
    Always returns true because Extant is a defined value.
    
    Overrides:
    
    isDefined in class Value
  - isDistinct
```
public boolean isDistinct()
```
    Always returns false because Extant is not a distinct value.
    
    Overrides:
    
    isDistinct in class Value
  - isDefinite
```
public boolean isDefinite()
```
    Always returns false because Extant is not a definite value.
    
    Overrides:
    
    isDefinite in class Value
  - isConstant
```
public boolean isConstant()
```
    Description copied from class: Item
    
    Returns true if this Item always evaluates to the same Item.
    
    Specified by:
    
    isConstant in class Item
  - unflattened
```
public Record unflattened()
```
    Always returns an empty Record because Extant is not a distinct value.
    
    Overrides:
    
    unflattened in class Value
  - not
```
public Value not()
```
    Overrides:
    
    not in class Value
  - stringValue
```
public String stringValue()
```
    Always returns the empty String because Extant behaves like an empty Record, which converts to a String by concatenating the string values of all its members, if all its members convert to string values.
    
    Overrides:
    
    stringValue in class Value
  - stringValue
```
public String stringValue(String orElse)
```
    Always returns the empty String because Extant behaves like an empty Record, which converts to a String by concatenating the string values of all its members, if all its members convert to string values.
    
    Overrides:
    
    stringValue in class Value
  - booleanValue
```
public boolean booleanValue()

```
public int typeOrder()
```
    Description copied from class: Item
    
    Returns the heterogeneous sort order of this Item. Used to impose a total order on the set of all items. When comparing two items of different types, the items order according to their typeOrder.
    
    Specified by:
    
    typeOrder in class Item
  - compareTo
```
public int compareTo(Item other)
```
    Specified by:

    Specified by:
    
    debug in interface Debug
    
    Specified by:
    
    debug in class Item
    
    Returns:
    
    the continuation of the output.
