    • Method Detail

      • getGraph

        public Graph<V,​E> getGraph()
        Specified by:
        getGraph in interface Layout<V,​E>
        Returns:
        the graph that this Layout refers to

      • getSize

        public java.awt.Dimension getSize()
        Specified by:
        getSize in interface Layout<V,​E>
        Returns:
        the current size of the visualization's space

      • initialize

        public void initialize()
        Description copied from interface: Layout
        Initializes fields in the node that may not have been set during the constructor. Must be called before the iterations begin.
        Specified by:
        initialize in interface Layout<V,​E>

      • isLocked

        public boolean isLocked​(V v)
        Specified by:
        isLocked in interface Layout<V,​E>
        Parameters:
        v - the vertex whose locked state is being queried
        Returns:
        true if the position of vertex v is locked

      • lock

        public void lock​(V v,
                 boolean state)
        Description copied from interface: Layout
        Locks or unlocks the specified vertex. Locking the vertex fixes it at its current position, so that it will not be affected by the layout algorithm. Unlocking it allows the layout algorithm to change the vertex's position.
        Specified by:
        lock in interface Layout<V,​E>
        Parameters:
        v - the vertex to lock/unlock
        state - true to lock the vertex, false to unlock it

      • reset

        public void reset()
        Specified by:
        reset in interface Layout<V,​E>

      • setGraph

        public void setGraph​(Graph<V,​E> graph)
        Specified by:
        setGraph in interface Layout<V,​E>
        Parameters:
        graph - the graph that this algorithm is to operate on

      • setInitializer

        public void setInitializer​(com.google.common.base.Function<V,​java.awt.geom.Point2D> initializer)
        Specified by:
        setInitializer in interface Layout<V,​E>
        Parameters:
        initializer - a function that specifies initial locations for all vertices

      • setLocation

        public void setLocation​(V v,
                        java.awt.geom.Point2D location)
        Description copied from interface: Layout
        Changes the layout coordinates of v to location.
        Specified by:
        setLocation in interface Layout<V,​E>
        Parameters:
        v - the vertex whose location is to be specified
        location - the coordinates of the specified location

      • setSize

        public void setSize​(java.awt.Dimension d)
        Specified by:
        setSize in interface Layout<V,​E>
        Parameters:
        d - the space to use to lay out this graph

      • apply

        public java.awt.geom.Point2D apply​(V arg0)
        Specified by:
        apply in interface com.google.common.base.Function<V,​E>
        Specified by:
        apply in interface java.util.function.Function<V,​E>
