Example usage for org.apache.commons.collections PredicateUtils uniquePredicate

Introduction

In this page you can find the example usage for org.apache.commons.collections PredicateUtils uniquePredicate.

Prototype

public static Predicate uniquePredicate() 

Source Link

Document

Creates a Predicate that returns true the first time an object is encountered, and false if the same object is received again.

Usage

From source file:BeanUtilsCollectionsV2.java

 public static void main(String args[]) {
   BeanPredicate predicate =//from   w  w  w .j  av a 2 s .c  om
     new BeanPredicate("title", PredicateUtils.uniquePredicate());

   Movie movie = new Movie();
   movie.setTitle("The Italian Job");

   Movie movie1 = new Movie();
   movie1.setTitle("The Italian Job");

   System.err.println(predicate.evaluate(movie)); // evaluates true
   System.err.println(predicate.evaluate(movie1)); // evaluates false

}
