void	addLayer (Layer layer)
	Adds this relation to the passed layer.If this relation is not already contained in the layer's graph, it will be added to the graph. Parameters layer to which this node should be added Since the method getLayers() retrieves all layers by accessing the layers in graph, this class does not contain an own collection of layers.
void	removeLayer (Layer layer)
	Removes this relation from the passed layer. Parameters layer from which this node should be removed Since the method getLayers() retrieves all layers by accessing the layers in graph, this class does not contain an own collection of layers.

Constructor & Destructor Documentation

org.corpus_tools.salt.graph.impl.RelationImpl< S extends Node, T extends Node >.RelationImpl

(

Relation< S, T >

delegate

)

Initializes an object of type Relation.

If delegate is not null, all functions of this method are delegated to the delegate object. Setting delegate makes this object to a container.

Parameters

a	delegate object of the same type.

Member Function Documentation

void org.corpus_tools.salt.graph.impl.RelationImpl< S extends Node, T extends Node >.basicSetGraph ( Graph  graph )

protected

This is an internally used method.

To implement a double chaining of Graph and Relation object when an relation is inserted into this graph and to avoid an endless invocation the insertion of an relation is splited into the two methods setGraph(Graph) and basicSetGraph(Graph). The invocation of methods is implement as follows:

Graph#addRelation(Relation)                      Relation#setGraph(Graph)
        ||             \ /                   ||
        ||              X                    ||
        \/             / \                   \/
Graph#basicAddRelation(Relation)            Relation#basicSetGraph(Graph)

That means method setGraph(Graph) calls basicSetGraph(Graph) and Graph#basicAddRelation(Relation). And method setGraph(Graph) calls Graph#basicAddRelation(Relation) and Relation#basicSetGraph(Graph).

Parameters

graph

graph which contains this relation

void org.corpus_tools.salt.graph.impl.RelationImpl< S extends Node, T extends Node >.basicSetGraph_WithoutRemoving ( Graph  graph )

protected

Same as basicSetGraph(Graph) but does not remove this relation from old graph, if it was not equal to the passed graph.

Parameters

graph
