        public static <T> com.google.common.reflect.Invokable<T,​T> constructor​(Class<T> ownerType,
                                                                             Class<?>... parameterTypes)
        returns an Invokable object that reflects a constructor present in the TypeToken type.
        Parameters:
        ownerType - corresponds to Invokable.getOwnerType()
        parameterTypes - corresponds to Constructor.getParameterTypes()
        Throws:
        IllegalArgumentException - if the constructor doesn't exist or a security exception occurred

      • constructors

        public static <T> Collection<com.google.common.reflect.Invokable<T,​T>> constructors​(com.google.common.reflect.TypeToken<T> ownerType)
        return all constructors or static factory methods present in the class as Invokables.
        Parameters:
        ownerType - corresponds to Invokable.getOwnerType()

      • method

        public static <T,​R> com.google.common.reflect.Invokable<T,​R> method​(com.google.common.reflect.TypeToken<T> ownerType,

        returns an Invokable object that links the method to its owner.
        Parameters:

        method - present in ownerType

      • method

        public static <T,​R> com.google.common.reflect.Invokable<T,​R> method​(Class<T> ownerType,
                                                                                String name,

        returns an Invokable object that reflects a method present in the TypeToken type. If there are multiple methods of the same name and parameter list, returns the method in the nearest ancestor with the most specific return type (see Class.getDeclaredMethod(java.lang.String, java.lang.Class<?>...)).
        Parameters:
        ownerType - corresponds to Invokable.getOwnerType()
        name - name of the method to be returned
        parameterTypes - corresponds to Method.getParameterTypes()
        Throws:
        IllegalArgumentException - if the method doesn't exist or a security exception occurred
