output/java_guava/1.4.19/TypeToken.java:219–223

Returns a new TypeToken where type variables represented by typeParam are substituted by typeArg. For example, it can be used to construct Map for any K and V type: {@code static TypeToken > mapOf( TypeToken

(TypeParameter<X> typeParam, TypeToken<X> typeArg)

  public final <X> TypeToken<T> where(TypeParameter<X> typeParam, TypeToken<X> typeArg) {
    TypeResolver resolver = new TypeResolver().where(ImmutableMap.of(new TypeResolver.TypeVariableKey(typeParam.typeVariable), typeArg.runtimeType));
    // If there's any type error, we'd report now rather than later.
    return new SimpleTypeToken<T>(resolver.resolveType(runtimeType));
  }
