Package org.tensorics.core.tensor

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:

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.
