What are differences between PageList, ValueList and Code-Pega-List?

Question

I run into a question about differences between PageList/ValueList and Code-Pega-List.

I know that

1) ValueList is a group of elementary type elements, which has unique index.

2) PageList is an indexed group of complex elements.

But what about class Code-Pega-List? Where I am allowed to utilize it?

When I was researching that question, I found out, that PageList or ValueList property cannot be passed as parameter where is awaited Code-Pega-List type property.

Thank you.

Firstly, Page List and ValueList is property types such as for example Page, Single Property, Page Group, etc. You can create property any type applies to any class, for example @baseclass.

Code-Pega-List is class. Class consist of several properties any types (Page, Page List, etc.). You can open class Code-Pega-List in application explorer and see it.

Code-Pega-List is a core class for Pega Platform. Many rules used it, such as methods in activity rule (Obj-Browse), report definition rule, etc. This class contains standard logic, for example count of elements in page-list contain in property .pxResults. I think that my answer help you understand difference.
