Constructor Detail

NodeImpl

public NodeImpl()

Default constructor

NodeImpl

@Deprecated
public NodeImpl(NodeImpl n)

Deprecated. Use ElementFactory.getNode(Node) instead.

Copy constructor.

Parameters:

n - source NodeImpl

Method Detail

setFactoryType

public void setFactoryType(java.lang.String n)

Description copied from interface: Linkable

Sets factory type

Specified by:

setFactoryType in interface Linkable

Parameters:

n - the factory type of the Linkable

See Also:

ElementFactory

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

setId

public void setId(int id)

Description copied from interface: Node

Sets Node's id

Specified by:

setId in interface Node

Parameters:

id - unique id

setExtendedId

public void setExtendedId(ExtendedId eid)

Convenience method to set Node's ExtendedId. Also sets node's id.

Parameters:

eid - ExtendedId

getExtendedId

public ExtendedId getExtendedId()

Description copied from interface: Linkable

Gets extendedId.

Specified by:

getExtendedId in interface Linkable

Returns:

a general id for Linkables.

getId

public int getId()

Description copied from interface: Node

Returns Node's id

Specified by:

getId in interface Node

Returns:

unique id

getLabel

public java.lang.String getLabel()

Description copied from interface: Linkable

Gets label.

Specified by:

getLabel in interface Linkable

Specified by:

getLabel in interface Node

Returns:

readable label

setLabel

public void setLabel(java.lang.String l)

Description copied from interface: Node

Sets label

Specified by:

setLabel in interface Node

Parameters:

l - readable label

getGroundingPamNode

public PamNode getGroundingPamNode()

Description copied from interface: Node

Returns the grounding PamNode.

Specified by:

getGroundingPamNode in interface Node

Returns:

PamNode, in PAM, underlying this node.

setGroundingPamNode

public void setGroundingPamNode(PamNode n)

Description copied from interface: Node

Used by factory to set the underlying PamNode for this node

Specified by:

setGroundingPamNode in interface Node

Parameters:

n - PamNode

equals

public boolean equals(java.lang.Object o)

This method compares this object with any kind of Node. returns true if the id of both are the same.

Overrides:

equals in class java.lang.Object

Parameters:

o - Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

updateNodeValues

public void updateNodeValues(Node n)

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

Specified by:

updateNodeValues in interface Node

Parameters:

n - Node whose values are used to update with.

See Also:

PamNodeImpl.updateNodeValues(Node), NodeStructureImpl.addNode(Node, String)

getConditionId

public ExtendedId getConditionId()

Description copied from interface: Condition

Gets id. The return object must be unique and it must be able to use as a map key i.e. Object.equals(Object) and Object.hashCode() must be overwritten for this id.

Specified by:

getConditionId in interface Condition

Returns:

Condition's unique id
