Method Detail

getGraph

public Graph getGraph()

Returns the container graph of this node.

Specified by:

getGraph in interface Layer<N extends Node,R extends Relation<N,N>>

Returns:

graph object which contains this node.

setGraph

public void setGraph(Graph graph)

Sets the container graph of this node. For double chaining between this Layer and the passed Graph object, the real insertion is done by method #basicSetGraph(Graph).

Specified by:

setGraph in interface Layer<N extends Node,R extends Relation<N,N>>

Parameters:

graph - graph which contains this layer

basicSetGraph

protected void basicSetGraph(Graph graph)

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

 Graph.addLayer(Layer)                      Layer.setGraph(Graph)
         ||             \ /                   ||
         ||              X                    ||
         \/             / \                   \/
 Graph#basicAddLayer(Layer)            Layer#basicSetGraph(Graph)
 

That means method setGraph(Graph) calls basicSetGraph(Graph) and Graph#basicAddLayer(Layer). And method setGraph(Graph) calls Graph#basicAddLayer(Layer) and Layer#basicSetGraph(Graph).

Parameters:

graph - graph which contains this layer

getNodes

public Set<N> getNodes()

Returns a set of all contained nodes, in the order how the nodes were inserted.

Specified by:

getNodes in interface Layer<N extends Node,R extends Relation<N,N>>

Returns:

all contained nodes

addNode

public void addNode(N node)

Adds the passed node to this layer. The insertion order is preserved. If this layer is contained by a graph, the passed node is also added to the graph in case it was not already contained in the graph.

Specified by:

addNode in interface Layer<N extends Node,R extends Relation<N,N>>

Parameters:

node - node to be inserted into this layer

removeNode

public void removeNode(N node)

Removes the passed node from this layer. If the passed relation is null, nothing is done.

Specified by:

removeNode in interface Layer<N extends Node,R extends Relation<N,N>>

Parameters:

node - to be removed

getRelations

public Set<R> getRelations()

Returns a set of all contained relations, in the order how the relations were inserted.

Specified by:

getRelations in interface Layer<N extends Node,R extends Relation<N,N>>

Returns:

all contained relations

addRelation

public void addRelation(Relation<? extends N,? extends N> relation)

Adds the passed relation to this layer. The insertion order is preserved. If this layer is contained by a graph, the passed relation is also added to the graph in case it was not already contained in the graph.

Specified by:

addRelation in interface Layer<N extends Node,R extends Relation<N,N>>

Parameters:

relation - relation to be inserted into this layer

removeRelation

public void removeRelation(Relation<? extends N,? extends N> relation)

Removes the passed relation from this layer. If the passed relation is null, nothing is done.

Specified by:

removeRelation in interface Layer<N extends Node,R extends Relation<N,N>>

Parameters:

relation - to be removed
