◆ areEqual() [1/2]

boolean javolution.util.internal.comparator.StandardComparatorImpl< E >.areEqual	(	E	e1,
		E	e2
	)

Definition at line 29 of file StandardComparatorImpl.java.

                                         {
         return (e1 == e2) || (e1 != null && e1.equals(e2));
     }

◆ areEqual() [2/2]

boolean javolution.util.function.Equality< T >.areEqual	(	T	left,
		T	right
	)

inherited

Indicates if the specified objects can be considered equal. This methods is equivalent to

(compare(o1, o2) == 0)

but usually faster.

Parameters

left	the first object (or `null`).
right	the second object (or `null`).

Returns: true if both objects are considered equal; false otherwise.

Here is the caller graph for this function:

		E	right

             return ((Comparable<E>) left).compareTo(right);
  
         // Empirical method (consistent with equals).
         if (left.equals(right))
             return 0;
         return left.hashCode() < right.hashCode() ? -1 : 1;
     }

◆ compare() [2/2]

int javolution.util.function.Equality< T >.compare	(	T	left,
		T	right
	)

inherited

Compares the specified objects for order. Returns a negative integer, zero, or a positive integer as the first argument is less than, possibly equal to, or greater than the second. Implementation classes should ensure that comparisons with

null

is supported.

Parameters

left	the first object.
right	the second object.

Returns: a negative integer, zero, or a positive integer as the first argument is less than, possibly equal to, or greater than the second.

◆ hashCodeOf() [1/2]

int javolution.util.internal.comparator.StandardComparatorImpl< E >.hashCodeOf ( E e )

Definition at line 24 of file StandardComparatorImpl.java.

                                {
         return (e == null) ? 0 : e.hashCode();
     }

◆ hashCodeOf() [2/2]

int javolution.util.function.Equality< T >.hashCodeOf ( T object )

inherited

Returns the hash code for the specified object (consistent with areEqual). Two objects considered equal have the same hash code. The hash code of null is always 0.

Parameters

object the object to return the hashcode for.
