IsLessThanOrEqual (Commons Functor 1.0-SNAPSHOT API)

java.lang.Object
- org.apache.commons.functor.core.comparator.IsLessThanOrEqual<T>

Type Parameters:
T - the binary predicate input types

All Implemented Interfaces:

Serializable, BinaryFunctor<T,T>, BinaryPredicate<T,T>, Functor
```
public final class IsLessThanOrEqual<T>
extends Object
implements BinaryPredicate<T,T>, Serializable
```
A BinaryPredicate that tests true iff the left argument is less than or equal to the right argument under the specified Comparator. When no (or a null Comparator is specified, a Comparable Comparator is used.

  - test
```
public boolean test(T left,
           T right)

    Evaluate this predicate. Return true iff the left parameter is less than or equal to the right parameter under my current Comparator.
    
    Specified by:
    
    test in interface BinaryPredicate<T,T>
    
    Parameters:
    left - the L element of the ordered pair of arguments

    Returns:
    the result of this test for the given arguments
  - equals
```
public boolean equals(Object that)
```
    Overrides:
    
    equals in class Object
  - equals
```
public boolean equals(IsLessThanOrEqual<?> that)
```
    Learn whether another IsLessThanOrEqual is equal to this.
    
    Parameters:

```
public static <T extends Comparable<?>> IsLessThanOrEqual<T> instance()
```
    Get a typed IsLessThanOrEqual instance.
    
    Type Parameters:
