  - newParameterizedType
```
public static ParameterizedType newParameterizedType(Type rawType,
                                                     Type... typeArguments)
```
    Returns a new parameterized type, applying typeArguments to rawType. The returned type does not have an owner type.
    
    Returns:
    
    a serializable parameterized type.
  - newParameterizedTypeWithOwner
```
public static ParameterizedType newParameterizedTypeWithOwner(Type ownerType,
                                                              Type rawType,
                                                              Type... typeArguments)
```
    Returns a new parameterized type, applying typeArguments to rawType and enclosed by ownerType.
    
    Returns:
    
    a serializable parameterized type.
  - arrayOf
```
public static GenericArrayType arrayOf(Type componentType)
```
    Returns an array type whose elements are all instances of componentType.
    
    Returns:
    
    a serializable generic array type.
  - subtypeOf
```
public static WildcardType subtypeOf(Type bound)
```
    Returns a type that represents an unknown type that extends bound. For example, if bound is CharSequence.class, this returns ? extends CharSequence. If bound is Object.class, this returns ?, which is shorthand for ? extends Object.
  - supertypeOf
```
public static WildcardType supertypeOf(Type bound)
```
    Returns a type that represents an unknown supertype of bound. For example, if bound is String.class, this returns ? super String.
  - listOf
```
public static ParameterizedType listOf(Type elementType)
```
    Returns a type modelling a List whose elements are of type elementType.
    
    Returns:
    
    a serializable parameterized type.
  - collectionOf
```
public static ParameterizedType collectionOf(Type elementType)
```
    Returns a type modelling a Collection whose elements are of type elementType.
    
    Returns:
    
    a serializable parameterized type.
  - setOf
```
public static ParameterizedType setOf(Type elementType)
```
    Returns a type modelling a Set whose elements are of type elementType.
    
    Returns:
    
    a serializable parameterized type.
  - mapOf
```
public static ParameterizedType mapOf(Type keyType,
                                      Type valueType)
```
    Returns a type modelling a Map whose keys are of type keyType and whose values are of type valueType.
    
    Returns:
    
    a serializable parameterized type.
  - providerOf
```
public static ParameterizedType providerOf(Type providedType)
```
    Returns a type modelling a Provider that provides elements of type elementType.
    
    Returns:
    
    a serializable parameterized type.
  - javaxProviderOf
```
public static Type javaxProviderOf(Type type)
```
    Returns a type modelling a Provider that provides elements of type elementType.
    
    Returns:
    
    a serializable parameterized type.
