```
eXclusive Or (Xor) 'Right' (or primary type) biased disjunct union. Often called Either, but in a generics heavy Java world Xor is half the length of Either. No 'projections' are provided, swap() and secondaryXXXX alternative methods can be used instead. Xor is used to represent values that can be one of two states (for example a validation result, either everything is ok - or we have an error). It can be used to avoid a common design anti-pattern where an Object has two fields one of which is always null (or worse, both are defined as Optionals).

fromPublisher

static <T> Xor<java.lang.Throwable,T> fromPublisher(org.reactivestreams.Publisher<T> pub)

Construct a Primary Xor from the supplied publisher

  
   ReactiveSeq<Integer> stream =  ReactiveSeq.of(1,2,3);
        
         Xor<Throwable,Integer> future = Xor.fromPublisher(stream);
        
         //Xor[1]

Parameters:: pub - Publisher to construct an Xor from
Returns:: Xor constructed from the supplied Publisher

fromIterable

static <ST,T> Xor<ST,T> fromIterable(java.lang.Iterable<T> iterable)

Construct a Primary Xor from the supplied Iterable

  
   List<Integer> list =  Arrays.asList(1,2,3);

Parameters:: iterable - Iterable to construct an Xor from
Returns:: Xor constructed from the supplied Iterable

secondary
```
static <ST,PT> Xor<ST,PT> secondary(ST value)
```
Create an instance of the secondary type. Most methods are biased to the primary type, so you will need to use swap() or secondaryXXXX to manipulate the wrapped value
```
  
   Xor.<Integer,Integer>secondary(10).map(i->i+1);
   //Xor.secondary[10]
    
    Xor.<Integer,Integer>secondary(10).swap().map(i->i+1);
    //Xor.primary[11]
 
 
```
Parameters:

value - to wrap

Returns:

Secondary instance of Xor

primary
```
static <ST,PT> Xor<ST,PT> primary(PT value)
```
Create an instance of the primary type. Most methods are biased to the primary type, which means, for example, that the map method operates on the primary type but does nothing on secondary Xors
```
  
   Xor.<Integer,Integer>primary(10).map(i->i+1);
   //Xor.primary[11]
    
   
 
 
```
Parameters:

value - To construct an Xor from

Returns:

Primary type instanceof Xor
