Class NumericControlAdapter

java.lang.Object

com.sun.tv.media.controls.AtomicControlAdapter

com.sun.tv.media.controls.NumericControlAdapter

All Implemented Interfaces:

AtomicControl, NumericControl, Control

public class NumericControlAdapter
extends AtomicControlAdapter
implements NumericControl

This class is a part of the porting layer implementation for JavaTV. A control that represents the state by a numeric value. The value can be any number represented as a float as long as it falls within the range and has the specified granularity/accuracy. For example, if the lower limit is 0 and the upper limit is 255 and the granularity is 1, then it can be assigned any integer value from 0 to 255.
