public sealed class Link : INotifyPropertyChanged, IChanged

For Dynamic Bayesian Networks, an order can be specified to link temporal nodes between different time slices.

Constructors

Link(Node, Node)

Initializes a new instance of the Link class with the parent node specified in from and the child in to.

Declaration
public Link(Node from, Node to)
Parameters
Type Name Description
Node from

The parent node.
Node to

The child node.
Exceptions
Type Condition
System.ArgumentNullException

Raised if either from or to is null.

Link(Node, Node, Int32)

Initializes a new instance of the Link class with a specified temporalOrder, the parent node specified in from and the child in to.

Declaration
public Link(Node from, Node to, int temporalOrder)
Parameters
Type Name Description
Node from

The parent node.
Node to

The child node.
System.Int32 temporalOrder

The temporal order. Must be greater than or equal to zero.
Remarks

If a temporal order is specified that is greater than zero, then a link can connect two nodes (which may be the same) at different times.

Exceptions
Type Condition
System.ArgumentNullException

Raised if either from or to is null.
System.ArgumentException

Raised if temporalOrder is negative.

Properties

Gets custom properties associated with this instance.

Declaration
public CustomPropertyCollection CustomProperties { get; }
Property Value
Type Description
CustomPropertyCollection

Custom properties allow storage of custom information, which will be saved with the network.

Optional description for the link.

Declaration
public string Description { get; set; }
Property Value
Type Description
System.String

The parent node of the directed link.

Declaration
public Node From { get; }
Property Value
Type Description
Node

The Index of this instance in the collection of links belonging to a network, or -1 if the link does not belong to a network.

Declaration
public int Index { get; }
Property Value
Type Description
System.Int32

The Network the link belongs to. Value will be null unless the link has been added to a network.

Declaration
[Browsable(false)]
public Network Network { get; }
Property Value
Type Description
Network

Gets or sets a value which determines the nature of the causal effect between the parent node (from) and a noisy child node (to).

Declaration
public NoisyOrder NoisyOrder { get; set; }
Property Value
Type Description
NoisyOrder

This property has no effect if the child node is not a noisy node.

Gets the temporal order of the link. If the link is not temporal, zero will be returned.

Declaration
public int TemporalOrder { get; }
Property Value
Type Description
System.Int32

The child node of the directed link.

Declaration
public Node To { get; }
Property Value
Type Description
Node

Methods

Copy(Node, Node, Int32)

Creates a new link, copying the properties from this instance, such as Description and CustomProperties.

Declaration
public Link Copy(Node from, Node to, int temporalOrder)
Parameters
Type Name Description
Node from

The parent node.
Node to

The child node.
System.Int32 temporalOrder

The temporal order. Must be greater than or equal to zero.
Returns
Type Description
Link

A new link instance.
