protected int id

Used to define vertex equivalence.

public AbstractElement()

Method Detail

getGraph

public ArchetypeGraph getGraph()

Description copied from interface: Element

Returns a reference to the graph that contains this element. If this element is not contained by any graph (is an "orphaned" element), returns null.

Specified by:

getGraph in interface Element

See Also:

Element.getGraph()

addGraph_internal

protected void addGraph_internal(AbstractArchetypeGraph g)

Attaches this vertex to the specified graph g.

removeGraph_internal

protected void removeGraph_internal()

Cleans up internal data structures after this element is removed from a graph.

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

See Also:

Object.hashCode()

initialize

protected void initialize()

Initializes all the data structures for this element. (This is used on cloned elements, since clone() copies some information that should not be in the new element.)
