Package chemaxon.marvin.space.monitor

Class DihedralMonitor

  • All Implemented Interfaces:
    chemaxon.marvin.space.UsableObject
    @PublicAPI
public class DihedralMonitor
extends MeasurementMonitor
    Monitor for measuring dihedral. Dihedral of 4 components is the angle between the 2 planes determinde by the first 3 and the second 3 components. Measuring dihedral has only sense if the 4 elements are 4 atoms of a molecule.
    Since:
    Marvin 4.0.2

    • Constructor Detail

      • DihedralMonitor

        public DihedralMonitor()
        Creates a new instance of DihedralMonitor

    • Method Detail

      • maximumItemCount

        public int maximumItemCount()
        Returns 4, as measuring dihedral is defined on 4 components.
        Specified by:
        maximumItemCount in class Monitor

      • getCoordinates

        public void getCoordinates​(float[] c)
        Returns the centroid of the second and third selected elements.
        Overrides:
        getCoordinates in class MeasurementMonitor
        Parameters:
        c - allocated array where coordinates will be put

      • select

        public void select()
        When the monitor is selected, a DihedralControl is created or changes its direction if it was alredy created.
        Specified by:
        select in interface chemaxon.marvin.space.UsableObject
        Overrides:
        select in class GraphicComponent

      • unSelect

        public void unSelect()
        Sets the monitor to be unselected and destroys the DihedralControl.
        Specified by:
        unSelect in interface chemaxon.marvin.space.UsableObject
        Overrides:
        unSelect in class Monitor

      • getComponent

        public GraphicComponent getComponent()
        Returns the molecule whose atoms are monitored.

      • setControl

        public void setControl​(DihedralControl control)
        Sets a DihedralControl to the monitor. It will change the coordinates of the elements, and makes the monitor refresh.

      • control

        public void control​(int v)
        Passes the control event to the control.

      • draw

        public void draw()
        Draws dotted lines between the components, and a circle around the middle line.
        Overrides:
        draw in class GraphicComponent
