Field Detail

groundingPamLink

protected PamLink groundingPamLink

PamLink in a PerceptualAssociativeMemory that grounds this Link.

Constructor Detail

LinkImpl

public LinkImpl()

Default constructor

LinkImpl

@Deprecated
public LinkImpl(Node src,
                           Linkable snk,
                           LinkCategory cat)

Deprecated. Use ElementFactory.getLink(Node, Linkable, LinkCategory) instead.

Constructs a new Link with specified parameters.

Parameters:

src - source Node

snk - sink Linkable

cat - link's LinkCategory

LinkImpl

@Deprecated
public LinkImpl(LinkImpl l)

Deprecated. Use ElementFactory.getLink(String, Node, Linkable, LinkCategory, String, String, double, double) instead.

Copy constructor

Parameters:

l - source LinkImpl

Method Detail

getExtendedId

public ExtendedId getExtendedId()

Description copied from interface: Linkable

Gets extendedId.

Specified by:

getExtendedId in interface Linkable

Returns:

a general id for Linkables.

getSink

public Linkable getSink()

Description copied from interface: Link

One end of the link which receives activation from the source.

Specified by:

getSink in interface Link

Returns:

sink linkable

getSource

public Node getSource()

Description copied from interface: Link

One end of the link which provides activation to the sink.

Specified by:

getSource in interface Link

Returns:

source linkable

getCategory

public LinkCategory getCategory()

Description copied from interface: Link

Get LinkCategory of this link.

Specified by:

getCategory in interface Link

Returns:

the category

setSink

public void setSink(Linkable snk)

Description copied from interface: Link

Set sink linkable.

Specified by:

setSink in interface Link

Parameters:

snk - the new sink

setSource

public void setSource(Node src)

Description copied from interface: Link

Set source linkable.

Specified by:

setSource in interface Link

Parameters:

src - the new source

setCategory

public void setCategory(LinkCategory c)

Description copied from interface: Link

Set LinkCategory.

Specified by:

setCategory in interface Link

Parameters:

c - the new category

getGroundingPamLink

public PamLink getGroundingPamLink()

Description copied from interface: Link

Get the grounding PamLink for this link.

Specified by:

getGroundingPamLink in interface Link

Returns:

the grounding pam link

setGroundingPamLink

public void setGroundingPamLink(PamLink l)

Description copied from interface: Link

Set the grounding PamLink for this link.

Specified by:

setGroundingPamLink in interface Link

Parameters:

l - the new grounding pam link

equals

public boolean equals(java.lang.Object obj)

This method compares this LinkImpl with any kind of Link. Two Links are equal if and only if they have the same id.

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

getLabel

public java.lang.String getLabel()

Description copied from interface: Linkable

Gets label.

Specified by:

getLabel in interface Linkable

Returns:

readable label

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

isSimpleLink

public boolean isSimpleLink()

Description copied from interface: Link

Returns whether Link is Simple (connects two nodes)

Specified by:

isSimpleLink in interface Link

Returns:

true if simple, false if complex (between a node and a simple link).

updateLinkValues

public void updateLinkValues(Link l)

This default implementation of Link has all of its attributes updated by NodeStructureImpl when links are updated. Therefore this class does not have to implement this method. Any subclass with specific class members (e.g. PamLinkImpl) should however override this method.

Specified by:

updateLinkValues in interface Link

Parameters:

l - Link whose values are used to update with.

See Also:

PamLinkImpl.updateLinkValues(Link), NodeStructureImpl.addLink(Link, String), NodeStructureImpl.getNewLink(Link, String, Node, Linkable, LinkCategory)

getFactoryType

public java.lang.String getFactoryType()

Description copied from interface: Linkable

Gets factory type

Specified by:

getFactoryType in interface Linkable

Returns:

the factory type of the Linkable

See Also:

ElementFactory

setFactoryType

public void setFactoryType(java.lang.String t)

Description copied from interface: Linkable

Sets factory type

Specified by:

setFactoryType in interface Linkable

Parameters:

t - the factory type of the Linkable
