Interface NumericControl

All Superinterfaces:

AtomicControl, Control

All Known Implementing Classes:

NumericControlAdapter

public interface NumericControl
extends AtomicControl

This interface 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.

float	getUpperLimit() The largest value assignable to this control.
float	getValue() Returns the value that the control currently represents.
