Package io.lionweb.model.impl

Class ProxyNode

java.lang.Object

io.lionweb.model.impl.AbstractClassifierInstance<Concept>

io.lionweb.model.impl.ProxyNode

All Implemented Interfaces:

ClassifierInstance<Concept>, HasFeatureValues, Node

public class ProxyNode
extends AbstractClassifierInstance<Concept>
implements Node

This is basic an ID holder adapted as a Node. It is used as a placeholder to indicate that we know which Node should be used in a particular point, but at this time we cannot/do not want to retrieve the data necessary to properly instantiate it.

public ProxyNode(@Nonnull
 String id)

Method Details

getParent

public Node getParent()

Description copied from interface: ClassifierInstance

The immediate parent of the Node. This should be null only for root nodes.

Specified by:

getParent in interface ClassifierInstance<Concept>

Specified by:

getParent in interface Node

getPropertyValue

public Object getPropertyValue(@Nonnull
 Property property)

Description copied from interface: HasFeatureValues

Get the property value associated with the specified property.

Specified by:

getPropertyValue in interface HasFeatureValues

setPropertyValue

public void setPropertyValue(Property property,
 @Nullable
 Object value)

Specified by:

setPropertyValue in interface HasFeatureValues

getChildren

public List<? extends Node> getChildren(@Nonnull
 Containment containment)

Description copied from interface: HasFeatureValues

This return all the Nodes directly contained into this Node under the specific Containment relation specified.

Specified by:

getChildren in interface HasFeatureValues

addChild

public void addChild(@Nonnull
 Containment containment,
 @Nonnull
 Node child)

Description copied from interface: HasFeatureValues

Add a child to the specified list of children associated with the given Containment relation. If the specified Containment does not allow for multiple values, and if a value is already set than the exception IllegalStateException will be thrown.

If the child has not a Concept compatible with the target of the Containement, the exception IllegalArgumentException will be thrown.

Specified by:

addChild in interface HasFeatureValues

removeChild

public void removeChild(@Nonnull
 Node node)

Description copied from interface: HasFeatureValues

Remove the given child from the list of children associated with the Node, making it a dangling Node. If the specified Node is not currently a child of this Node the exception IllegalArgumentException will be thrown.

Specified by:

removeChild in interface HasFeatureValues

Overrides:

removeChild in class AbstractClassifierInstance<Concept>

getReferenceValues

@Nonnull
public List<ReferenceValue> getReferenceValues(@Nonnull
 Reference reference)

Specified by:

getReferenceValues in interface HasFeatureValues

addReferenceValue

public void addReferenceValue(@Nonnull
 Reference reference,
 @Nullable
 ReferenceValue referredNode)

Description copied from interface: HasFeatureValues

Add the Node to the list of Nodes referred to from this Node under the given Reference.

If the Reference is not multiple, any previous value will be replaced.

The Node specified should be either part of this Node's Model or of Models imported by this Node's Model. If that is not the case the exception IllegalArgumentException will be thrown.

If the referredNode has not a Concept compatible with the target of the Reference, the exception IllegalArgumentException will be thrown.

Specified by:

addReferenceValue in interface HasFeatureValues

getID

@Nonnull
public String getID()

Description copied from interface: Node

This return the Node ID.

A valid Node ID should not be null, but this method can return a null value in case the Node is in invalid state.

Specified by:

getID in interface ClassifierInstance<Concept>

Specified by:

getID in interface Node

getClassifier

public Concept getClassifier()

Description copied from interface: Node

The concept of which this Node is an instance. The Concept should not be abstract.

Specified by:

getClassifier in interface ClassifierInstance<Concept>

Specified by:

getClassifier in interface Node

getAnnotations

public List<AnnotationInstance> getAnnotations()

Description copied from interface: ClassifierInstance

Return all the annotations associated to this ClassifierInstance.

Specified by:

getAnnotations in interface ClassifierInstance<Concept>

Overrides:

getAnnotations in class AbstractClassifierInstance<Concept>

getContainmentFeature

public Containment getContainmentFeature()

Description copied from interface: Node

Return the Containment feature used to hold this Node within its parent. This will be null only for root nodes or dangling nodes (which are not distinguishable by looking at the node itself).

Specified by:

getContainmentFeature in interface Node

Returns:

the Containment holding the Node. Or null, if the Node has no parent

See Also:

• Ecore equivalent EObject.eContainingFeature in documentation.

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

removeChild

public void removeChild(@Nonnull
 Containment containment,
 int index)

Description copied from interface: HasFeatureValues

Remove the child at the given index, considering the children under the given containment.

If there is no match the exception IllegalArgumentException will be thrown.

Specified by:

removeChild in interface HasFeatureValues

Overrides:

removeChild in class AbstractClassifierInstance<Concept>

removeReferenceValue

public void removeReferenceValue(@Nonnull
 Reference reference,
 @Nullable
 ReferenceValue referenceValue)

Description copied from interface: HasFeatureValues

Remove the first reference value that is equal to the given referenceValue. Node. If there is no match the exception IllegalArgumentException will be thrown.

Specified by:
