hi
I am trying to create a vf page to fetch related opportunities for specific account and to add pagination.
Whenever I try to save my code I get the below error:
Error: Compile Error: Method does not exist or incorrect signature: [ListPaginationBase].initializePagination(List<NewStockTransferExtension.materialWrapperList>, Integer) 
 

public class NewStockTransferExtension{

    public ListPaginationBase ConstructionOpportunityList {get; set;}
    
    public list<materialWrapperList> materialWrapperList{get;set;}
  
    public Account currentAccount {get; set;}

    public NewStockTransferExtension(ApexPages.StandardController controller) {
        ConstructionOpportunityList = new ListPaginationBase();
        currentAccount = (Account) controller.getRecord();

       
        ConstructionOpportunityList.initializePagination(materialWrapperList, 20);
       
    }
        public class materialWrapperList
        {
            public  boolean checked{get;set;}
            Public Opportunity ConstructionOpportunityList {get;set;}
            public materialWrapperList(Opportunity ConstructionOpportunityList ){
            this.ConstructionOpportunityList = ConstructionOpportunityList ;
            }
         }



}

 

I wrote the below test class and it only covered 45% of my code, it doesn;t cover the next and previouse page reference

        if (pageSize <= 0 || listSize <= 0)
            return 1;
        else
            return (Integer) Math.ceil((Decimal)listSize / (Decimal)pageSize);

        return currentPageIndex > 0;
    }
    
    public Integer getfirstRowIndex() {
        //Returns the index of the first row to show in the PageBlockTable using the first attribute
        return currentPageIndex * pageSize;

        if(getHasPrevious())
            currentPageIndex = 0;
        
        return null;
    }
    
    public PageReference lastAction() {
        //Action fired when the user click the Last Button
        //Set the Page Index to pages count - 1
        
        if(getHasNext())
            currentPageIndex = getPageCount() - 1;

    }

        if(getHasNext())

    }

hi
I am trying to create a vf page to fetch related opportunities for specific account and to add pagination.
Whenever I try to save my code I get the below error:
Error: Compile Error: Method does not exist or incorrect signature: [ListPaginationBase].initializePagination(List<NewStockTransferExtension.materialWrapperList>, Integer) 
 

public class NewStockTransferExtension{

    public ListPaginationBase ConstructionOpportunityList {get; set;}
    
    public list<materialWrapperList> materialWrapperList{get;set;}
  
    public Account currentAccount {get; set;}

    public NewStockTransferExtension(ApexPages.StandardController controller) {
        ConstructionOpportunityList = new ListPaginationBase();
        currentAccount = (Account) controller.getRecord();

       
        ConstructionOpportunityList.initializePagination(materialWrapperList, 20);
       
    }
        public class materialWrapperList
        {
            public  boolean checked{get;set;}
            Public Opportunity ConstructionOpportunityList {get;set;}
            public materialWrapperList(Opportunity ConstructionOpportunityList ){
            this.ConstructionOpportunityList = ConstructionOpportunityList ;
            }
         }



}

 

Hi folks,
      Can anyone tell me how to write the test class for pagination?
Below is my test class which covers 85%  but it didnt covers the hasnext,previous and pagenumber method.
 

@isTest(SeeAllData=true)
public class PaginationControllerTest {
    
        public static testMethod void testSearchAccount() {
        PageReference pageRef = Page.TestPagination;
        Test.setCurrentPage(pageRef);

        // Instantiate a new controller with all parameters in the page
    
        PaginationController  p=new PaginationController ();
        
        p.getAccountList();
        p.Next();
        p.First();
        p.Last();
        p.Previous();
        p.Cancel();
        p.con.getHasPrevious();
        p.con.getHasNext();
        p.con.getPageNumber();
        
       
     }

}

Controller:

public class PaginationController {
    public ApexPages.StandardSetController con {
        get {
                if(con == null) {
                    con = new ApexPages.StandardSetController(Database.getQueryLocator([Select Id, Name,Type FROM Account])); 
                    con.setPageSize(5);                      
                }
                return con;
        }
        set;
    }
    
    public List<Account> getAccountList(){
        return (List<Account>)con.getRecords();
    }
    
    public Boolean hasNext {
        get {
                return con.getHasNext();
            }
        set;
    }
   
    public Boolean hasPrevious {
        get {
            return con.getHasPrevious();
        }
        set;
    }
   
    public Integer pageNumber {
        get {
            return con.getPageNumber();
        }
        set;
    }
