Method Detail

getNodes

EList<Node> getNodes()

Returns the value of the 'Nodes' containment reference list. The list contents are of type Node. It is bidirectional and its opposite is 'Graph'.

Returns:

the value of the 'Nodes' containment reference list.

HenshinPackage.getGraph_Nodes(), Node.getGraph()

getEdges

EList<Edge> getEdges()

Returns the value of the 'Edges' containment reference list. The list contents are of type Edge. It is bidirectional and its opposite is 'Graph'.

Returns:

the value of the 'Edges' containment reference list.

See Also:

HenshinPackage.getGraph_Edges(), Edge.getGraph()

getFormula

Formula getFormula()

Returns the value of the 'Formula' containment reference.

Returns:

the value of the 'Formula' containment reference.

See Also:

setFormula(Formula), HenshinPackage.getGraph_Formula()

setFormula

void setFormula(Formula value)

Sets the value of the 'Formula' containment reference.

Parameters:

value - the new value of the 'Formula' containment reference.

getFormula()

getRule

Rule getRule()

Returns the Rule this graph is contained in or null if it is not directly contained in a Rule.

getNode

Node getNode(String name)

Get the first node in this graph that has the given argument name.

getNodes

EList<Node> getNodes(EClass nodeType)

Get all nodes in this graph that are of a specific type. This returns an unmodifiable list of nodes.
