Class BasicGraphable

  • All Implemented Interfaces:
    Serializable, Graphable
    Direct Known Subclasses:
    BasicDirectedEdge, BasicDirectedNode, BasicEdge, BasicNode
    public abstract class BasicGraphable
extends Object
implements Graphable, Serializable
    Basic implementation of Graphable. This class serves as the root in the hierarchy of basic graph components.

    Components in the basic hierarchy implement the Serializable interface. However serialization will fail if a Graphable object contains a reference to a non serializable object.

    • Constructor Detail

      • BasicGraphable

        public BasicGraphable()
        Constructs a new a graph component. Sets the visited flag to false, counter to -1, and generates a new id.

    • Method Detail

      • getID

        public int getID()
        Description copied from interface: Graphable
        Returns an identifier for the component. This number is not necessarily persistent or unique.
        Specified by:
        getID in interface Graphable
        Returns:
        Identifying integer.
        See Also:
        Graphable.getID()

      • setID

        public void setID​(int id)
        Description copied from interface: Graphable
        Sets the identifying integer for the component.
        Specified by:
        setID in interface Graphable
        Parameters:
        id - New identifying integer.
        See Also:
        Graphable.setID(int)

      • getObject

        public Object getObject()
        Description copied from interface: Graphable
        Returns the underlying object referenced by the graph component.
        Specified by:
        getObject in interface Graphable
        Returns:
        Underlying object reference, the entity being modelled by graph component.
        See Also:
        Graphable.getObject()

      • setObject

        public void setObject​(Object obj)
        Description copied from interface: Graphable
        Sets the underlying object reference for the component.
        Specified by:
        setObject in interface Graphable
        Parameters:
        obj - The entity being modelled by the graph component.
        See Also:
        Graphable.setObject(Object)

      • isVisited

        public boolean isVisited()
        Description copied from interface: Graphable
        Determines if the component has been marked as visited. The visited flag serves as a binary switch for the component which can be used for graph queries, graph traversals, or user defined purposes.
        Specified by:
        isVisited in interface Graphable
        Returns:
        True if visited(on), false if unvisited(off).
        See Also:
        Graphable.isVisited()

      • setVisited

        public void setVisited​(boolean visited)
        Description copied from interface: Graphable
        Marks the component as being visited/unvisited. The visited flag serves as a binary switch for the component which can be used for graph queries, graph traversals, or user defined purposes.
        Specified by:
        setVisited in interface Graphable
        Parameters:
        visited - True if visited(on), false if unvisited(off).
        See Also:
        Graphable.setVisited(boolean)

      • getCount

        public int getCount()
        Description copied from interface: Graphable
        Returns the value of the counter for the component. Graph components have a counter associated with them to be used for graph queries, graph traversals, or user defined purposes.
        Specified by:
        getCount in interface Graphable
        Returns:
        int The value of the counter for the component.
        See Also:
        Graphable.getCount()

      • setCount

        public void setCount​(int count)
        Description copied from interface: Graphable
        Sets the value of the counter for the component. Graph components have a counter associated with them to be used for graph queries, graph traversals, or user defined purposes.
        Specified by:
        setCount in interface Graphable
        Parameters:
        count - The new value of the counter for the component.
        See Also:
        Graphable.setCount(int)
