Usage

From source file:com.discursive.jccook.collections.predicate.PredicatedMapExample.java

public void start() {
    // Create the Predicates
    ValidTeamPredicate validTeam = new ValidTeamPredicate();
    ValidCoachPredicate validCoach = new ValidCoachPredicate();

    // Tie two Predicates together into an AndPredicate
    AndPredicate valuePredicate = new AndPredicate(validTeam, validCoach);

    // Decorate a HashMap with a predicate on the value
    teamMap = PredicatedMap.decorate(new HashMap(), null, valuePredicate);

    // Manufacture some teams
    Team redSox = new Team("Red Sox", new Coach("Patrick", "Moloney"));
    Team yankees = new Team("Yankees", new Coach("David", "McGarry"));
    Team dodgers = new Team("Dodgers", new Coach("Nick", "Taylor"));
    Team twins = new Team(null, new Coach("Patrick", "Moloney"));
    Team braves = new Team("Braves", null);

    // The follow put calls should work fine
    teamMap.put("RedSox", redSox);
    teamMap.put("Yankees", yankees);
    teamMap.put("Dodgers", dodgers);

    // This put should fail because the team name is null
