  extended by gov.sandia.cognition.util.AbstractCloneableSerializable
      extended by gov.sandia.cognition.learning.function.kernel.DefaultKernelContainer<InputType>
Type Parameters:
InputType - The type of the input to the Kernel. For example, Vector.
All Implemented Interfaces:
KernelContainer<InputType>, CloneableSerializable, Serializable, Cloneable

public class DefaultKernelContainer<InputType>
extends AbstractCloneableSerializable
implements KernelContainer<InputType>

The DefaultKernelContainer class implements an object that contains a kernel inside. It is extended by various other classes, including Kernels that contain an internal kernel that is used.

Field Detail


protected Kernel<? super InputType> kernel
The internal kernel.

Constructor Detail


public DefaultKernelContainer()
Creates a new instance of KernelContainer. The kernel defaults to null.


public DefaultKernelContainer(Kernel<? super InputType> kernel)
Creates a new instance of KernelContainer with the given kernel.

kernel - The kernel to put in the container.


public DefaultKernelContainer(DefaultKernelContainer<? super InputType> other)
Creates a new copy of a KernelContainer and the kernel inside.

other - The KernelContainer to copy.
Method Detail


public DefaultKernelContainer<InputType> clone()
Description copied from class: AbstractCloneableSerializable
This makes public the clone method on the Object class and removes the exception that it throws. Its default behavior is to automatically create a clone of the exact type of object that the clone is called on and to copy all primitives but to keep all references, which means it is a shallow copy. Extensions of this class may want to override this method (but call super.clone() to implement a "smart copy". That is, to target the most common use case for creating a copy of the object. Because of the default behavior being a shallow copy, extending classes only need to handle fields that need to have a deeper copy (or those that need to be reset). Some of the methods in ObjectUtil may be helpful in implementing a custom clone method. Note: The contract of this method is that you must use super.clone() as the basis for your implementation.
