UnaryPredicateUnaryFunction (Commons Functor 1.0-SNAPSHOT API)

java.lang.Object
- org.apache.commons.functor.adapter.UnaryPredicateUnaryFunction<A>

Type Parameters:
A - the argument type.

All Implemented Interfaces:

Serializable, Functor, UnaryFunction<A,Boolean>, UnaryFunctor<A>
```
public final class UnaryPredicateUnaryFunction<A>
extends Object
implements UnaryFunction<A,Boolean>, Serializable
```
Adapts a UnaryPredicate to the UnaryFunction interface.
Note that although this class implements Serializable, a given instance will only be truly Serializable if the underlying predicate is. Attempts to serialize an instance whose delegate is not Serializable will result in an exception.

    evaluate in interface UnaryFunction<A,Boolean>
    
    Parameters:
    obj - the A object to evaluate
    
    Returns:
    a non-null Boolean instance
  - equals
```
public boolean equals(Object that)
```
    Overrides:
    
    equals in class Object
  - equals
```
public boolean equals(UnaryPredicateUnaryFunction<?> that)
```
    Learn whether another UnaryPredicateUnaryFunction is equal to this.
    
    Parameters:
    that - UnaryPredicateUnaryFunction to test
    
    Returns:
    boolean
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - adapt
```
public static <A> UnaryPredicateUnaryFunction<A> adapt(UnaryPredicate<? super A> predicate)
```
    Adapt a UnaryPredicate to the UnaryFunction interface.
    
    Type Parameters:
    A - the argument type.
    Parameters:
    predicate - to adapt
    
    Returns:
    UnaryPredicateUnaryFunction
