Method Details

withTypeParameters

InstancioApi<T> withTypeParameters(Class<?>... types)

Method for supplying type parameters for generic classes.

Example:

   List<Address> addresses = Instancio.of(List.class)
           .withTypeParameters(Address.class)
           .create();
 

This method can be used when the type parameters need to be supplied dynamically at runtime, however it also has a couple of limitations:

• its usage produces an unchecked assignment warning
• it cannot be used for nested generics, such as Map<String, List<Integer>>

The recommended approach for instantiating generic classes is using TypeTokens:

   List<Address> addresses = Instancio.create(new TypeToken<List<Address>>() {});
 

Parameters:

types - one or more type arguments

Returns:

API builder reference

Since:

1.0.1
