Class MaxValue<T>

java.lang.Object
  net.sf.jga.fn.Functor<R>
      net.sf.jga.fn.UnaryFunctor<java.util.Collection<? extends T>,T>
          net.sf.jga.fn.algorithm.MaxValue<T>

All Implemented Interfaces:

java.io.Serializable, Visitable

Deprecated. This functionality is moved into Summarize

public class MaxValue<T>
extends UnaryFunctor<java.util.Collection<? extends T>,T>

Identifies the largest value in a collection.

To serialize a MaxValue, the comparator passed at construction must be Serializable.

Constructor Detail

MaxValue

public MaxValue(java.util.Comparator<T> comp)

Deprecated.

Builds a MaxValue functor that will use the given comparator to compare elements in the collection. Typically, the functor would compare its two arguments and return the greater value.

Throws:

java.lang.IllegalArgumentException - if the Comparator is null

Method Detail

getComparator

public java.util.Comparator<T> getComparator()

Deprecated.

Returns the comparator used to order values in the collection.

fn

public T fn(java.util.Collection<? extends T> collection)

Deprecated.

Returns the largest value in the collection

Specified by:

fn in class UnaryFunctor<java.util.Collection<? extends T>,T>

Throws:

NoSuchElementException - if the collection is empty

accept

public void accept(Visitor v)

Deprecated.

Calls the Visitor's visit(MaxValue) method, if it implements the nested Visitor interface.

Specified by:

accept in interface Visitable

Overrides:

accept in class Functor<T>

toString

public java.lang.String toString()

Deprecated.

Overrides:

toString in class java.lang.Object
