Interface Summary

Interface	Description
Mappable<V>	Allows its implementors to provide a method to view the tensor as a map from position to values.
MappableTensor<V>	Enhances the tensor interface by a method to view the tensor as a map from position to values.
Scalar<V>	The specialization of a tensor with zero dimensions and exactly one value.
Tensor<E>	The top interface for Tensor like objects.
TensorBuilder<V>	The interface any builder of a tensor have to implement.
Tensoric<V>	The most generic interface of a multidimensional object within tensorics.
TensorView<V>	Marks a tensor, which is a view on one or more other tensor(s).
VerificationCallback<S>	A callback that can be passed to a builder so that it can check any new scalar added if it is conform to certain criteria.

Class Summary

Class	Description
AbstractScalar<V>	A base class for scalars, that already guarantees the shape and the correct delegation of the get() methods to the value method.
AbstractTensor<V>	Provides sceletal behaviour of tensors.
AbstractTensorBuilder<V>
BroadcastedTensorView<V>	Lets a tensors appear as a tensor with a bigger shape.
Coordinates	Utility methods to handle coordinates
ImmutableScalar<V>	An immutable implementation of a scalar (a tensor with zero dimensions and exactly one value).
ImmutableTensor<V>	Default Implementation of Tensor.
ImmutableTensor.Builder<V>	A builder for an immutable tensor.
Position	Defines the position of a value within a tensor in the N-dimensional coordinate space.
PositionPair	A pair of positions, usually representing a position in the left tensor of an operation and its corresponding position in the right tensor.
Positions	Contains utility methods for position objects.
Positions.DimensionStripper	A functional object to transform positions to other positions with the dimensions stripped as given in the constructor.
Shape	Defines the shape of a tensor.
Shape.Builder	The builder for a tensor shape.
Shapes	Contains utility methods to deal with tensor shapes.
TensorPair<V>	A pair of tensors which are used together in several occasions.

Package org.tensorics.core.tensor Description

This package contains the base classes for tensoric elements. There are in general two aspects taken into account by this hierarchy:

1. Deferrence: A tensoric can either be a real object containing data or it can be 'deferred', meaning that is simply a placeholder for the real object, which will be determined later.
2. Tensoric base types: The base type for all real data-holding objects is the Tensor. A special version of it is a scalar, which has zero dimensions (order, rank). A special treatment is sometimes required for the elements of the tensors themselves: These can be java objects of any type. However, if calculations have to be performed by them, than a mathematical environment is required for them.

An overview of the actual types is depicted in the following diagram:
