extends java.lang.Object
    This class gives an access to the methods for Tensorbacked object support.

    • Method Detail

      • dimensionsOf

        public static <T extends Tensorbacked<?>> java.util.Set<java.lang.Class<?>> dimensionsOf​(java.lang.Class<T> tensorBackedClass)
        Retrieves the dimensions from the given class inheriting from tensor backed. This is done by inspecting the Dimensions annotation.
        Parameters:
        tensorBackedClass - the class for which to determine the dimensions
        Returns:
        the set of dimensions (classses of coordinates) which are required to create an instance of the given class.

      • createBackedByTensor

        public static <V,​T extends Tensorbacked<V>> T createBackedByTensor​(java.lang.Class<T> tensorBackedClass,
                                                                         Tensor<V> tensor)
        Creates an instance of a class backed by a tensor.
        Parameters:
        tensorBackedClass - the type of the class for which to create an instance.
        tensor - the tensor to back the instance
        Returns:
        a new instance of the given class, backed by the given tensor
