public class Needle
extends NeedleGauge
implements Serializable
This gauge is a specialisation of NeedleGauge. It allows the synchronization to be expressed in terms of a damping value.

Constructor Index

o Needle()
Create a RAGNeedle with critical damping.

Method Index

o copyright()
o getDamping()
Return the needle damping.
o setDamping(double)
Specify the needle damping.

Constructors

o Needle 
 public Needle()
Create a RAGNeedle with critical damping. All other properties take their default values as defined by com.ibm.eou.toolkit.gauge.NeedleGauge().

Methods

o copyright 
 public static String copyright()
o setDamping 
 public void setDamping(double newvalue)
Specify the needle damping. It is constrained to positive real numbers, with values less 1 being under damped such that the needle will tend to oscillate before settling on its new value.

o getDamping 
 public double getDamping()
Return the needle damping.
