Custom Controller - Example 1

// Custom controller for Visualforce Page - Example 1
// Probably the nicest part of this controller is: 'AND OwnerId = :UserInfo.getUserId'  
// which utilizes the getUserId method from the UserInfo class. More info here: salesforce.com/us/developer/docs/apexcode/Content/apex_methods_system_userinfo.htm

public class OpportunityRevisitDatesController {

    public ApexPages.StandardSetController ssc { // allows us to create list controllers
        get {
            if(ssc == null) { 

                ssc = new ApexPages.StandardSetController(Database.getQueryLocator( // instantiate via a query locater
                    [SELECT Name, Account.Name, Revisit_Date__c FROM Opportunity WHERE Revisit_Date__c <= TODAY AND OwnerId = :UserInfo.getUserId()]));
            }
            return ssc;
        }
        set; 
    } 
    
    public List<Opportunity> getOpportunities() { // Method of List collection of sObject Opportunity called getOpportunities
        return (List<Opportunity>) ssc.getRecords(); // return List of sObject results from ssc (Standard Set Controller)
