| EqualTo | | public class EqualTo extends Equality (Code) | | Binary Predicate that returns TRUE for object arguments x and
y when x == y using the built-in equals() method or an optional
Comparator given at construction. By default, this functor will not throw
NullPointerException: it will return true if both runtime arguments are null
but false if only one is null. If an optional comparator is used, then its
implementation will determine if a NullPointerException is thrown when passed
a null argument.
To serialize an Equal functor, the comparator passed at construction(if any)
must be Serializable.

| public | EqualTo()
Builds an EqualTo that uses the built-in equals method. | | public | EqualTo(Comparator<? super T> comp)
Builds an EqualTo that uses the given comparator. |

| EqualTo | | public EqualTo()(Code) | | Builds an EqualTo that uses the built-in equals method.

| EqualTo | | public EqualTo(Comparator<? super T> comp)(Code) | | Builds an EqualTo that uses the given comparator.
|
| accept | | public void accept(net.sf.jga.fn.Visitor v)(Code) | | Calls the Visitor's visit(EqualTo) method, if it
implements the nested Visitor interface.
|
| fn | | public Boolean fn(T x, T y)(Code) | | Given arguments x and y, returns x.equals(y). Will not
throw NullPointerException if either x or y are null: will return true
if both x and y are null and false if either x or y are null.
