UnaryEquator (Apache Mina SSHD :: Common support utilities 2.7.0 API)

Type Parameters:

T - Type of compared entity

All Superinterfaces:

BiPredicate<T,T>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface UnaryEquator<T>
extends BiPredicate<T,T>
```
Checks equality between 2 entities of same type

default UnaryEquator<T> and(UnaryEquator<? super T> other)
```
    Returns a composed equator that represents a short-circuiting logical AND of this equator and another. When evaluating the composed equator, if this equator is false, then the other equator is not evaluated.
    
    Parameters:
    
    other - The other (never null equator
    
    Returns:
    
    The compound equator
  - or
```
default UnaryEquator<T> or(UnaryEquator<? super T> other)
```
    Returns a composed equator that represents a short-circuiting logical AND of this equator and another. When evaluating the composed equator, if this equator is true, then the other equator is not evaluated.
    
    Parameters:
    
    other - The other (never null equator
    
    Returns:
    
    The compound equator
  - negate
```
default UnaryEquator<T> negate()
```
    Specified by:
    
    negate in interface BiPredicate<T,T>
    
    Returns:
    
    an equator that represents the logical negation of this one
  - isSameReference
```
static <T> boolean isSameReference(T o1,
                                   T o2)
```
  - defaultEquality
```
static <T> UnaryEquator<T> defaultEquality()
```
    Type Parameters:
    
    T - Type of entity
    
    Returns:
    
    The default equality checker
    
    See Also:
    
    Objects.equals(Object, Object)
  - referenceEquality
```
static <T> UnaryEquator<T> referenceEquality()
```
    Type Parameters:
    
    T - Type of entity
    
    Returns:
    
    An equator that checks reference equality
    
    See Also:
    
    isSameReference(Object, Object)
  - comparing
```
static <T> UnaryEquator<T> comparing(Comparator<? super T> c)
```
    Converts a Comparator into a UnaryEquator that returns true if the comparator returns zero
    
    Type Parameters:
    
    T - Type of entity
    
    Parameters:
    
    c - The (never null) comparator
    
    Returns:
    
    The equivalent equator
  - verum
```
static <T> UnaryEquator<T> verum()
```
    Type Parameters:
    
    T - Type of evaluated entity
    
    Returns:
    
    A UnaryEquator that returns always true
    
    See Also:
    
    verum
  - falsum
```
static <T> UnaryEquator<T> falsum()
```
    Type Parameters:
    
    T - Type of evaluated entity
    
    Returns:
    
    A UnaryEquator that returns always false
    
    See Also:
