Interface SelectionSet

@ProviderType
public interface SelectionSet

Interface to wrap information from GraphQL DataFetchingFieldSelectionSet.

Mainly it keeps information about fields name that got selected.

 For example:
 
   queryName {
       field1
       field2 {
           ... on Type1 {
               field3
           }
       }
       field4
       field5 {
           field6
           field7 {
               field8
           }
       }
   }
 
 

Would result in a mapping with corresponding SelectedField(s).

field1 would be accessible with qualified name "field1" while field3 would be accessible with qualified name "field2/Type1/field3" and field8 would be accessible with qualified name "field5/field7/field8"

Type1 would be a SelectedField with isInline() returning true
