I have a collection property of an object of type Property and would like to determine the membership type of the collection. Does anyone know how to do this.

The CollClass class has a method getMemberType that returns the type of the members in a collection. For Example the following code fragment will assign Object to the variable c and then write Object on the screen.

vars
oa : ObjectArray;
c : Type;begin

create oa transient;
c := oa.class.CollClass.getMemberType;
write c.name;
delete oa;
end;
