TypeTupleSet (randoop 4.3.3 API)

java.lang.Object
- randoop.reflection.TypeTupleSet

```
class TypeTupleSet
extends Object
```
Represents a set of lists of candidate type arguments for a ParameterizedType, and uses this set to construct substitutions for a list of TypeArgument objects.
Starts as a singleton list with the empty list, which is expanded by repeated use of the extend(List) method that adds new types to the lists in the set, then the set of Substitution objects is created by a call to filter(List).

- Method Detail
  - extend
```
public void extend(List<ReferenceType> types)
```
    Extends all of the elements of the current tuple set with all of the types in the given list. In other words, if there are k types given then each tuple will be replaced by k new tuples extended by one of the input types.
    
    Parameters:
    
    types - the list of types
  - filter
```
List<Substitution> filter(List<TypeVariable> typeParameters)
```
    Returns a list of substitutions for type tuples that can instantiate the given list of TypeArgument objects, and filters the set of tuples.
    
    Parameters:
    
    typeParameters - the type arguments
    
    Returns:
    
    the list of substitutions that instantiate the type arguments
