RateRange

• java.lang.Object

Fields Summary
float	minimum
float	maximum
float	current
boolean	exact

Constructors Summary
RateRange() super();
public RateRange(RateRange r) Copy constructor. minimum = r.minimum; maximum = r.maximum; current = r.current; exact = r.exact;
public RateRange(float init, float min, float max, boolean isExact) Constructor using required values. param init The initial value for this rate. param min The minimum value that this rate can take. param max The maximum value that this rate can take. param isExact Set to true if the source rate does not vary when using this rate range. minimum = min; maximum = max; current = init; exact = isExact;

Methods Summary
public float	getCurrentRate() Get the current rate. return The current rate. return current;
public float	getMaximumRate() Get the maximum rate supported by this range. return The maximum rate. return maximum;
public float	getMinimumRate() Get the minimum rate supported by this range. return The minimum rate. return minimum;
public boolean	inRange(float rate) Determine whether or not a particular value is within the range of supported rates. param The rate to test. return Returns true if the specified rate is supported. return (minimum < rate) && (rate < maximum);
public boolean	isExact() Determine whether or not the source will maintain a constant speed when using this rate. If the rate varies, synchronization is usually impractical. return Returns true if the source will maintain a constant speed at this rate. return exact;
public float	setCurrentRate(float rate) Set the current rate. Returns the rate that was actually set. This implementation just returns the specified rate, subclasses should return the rate that was actually set. param rate The new rate. current = rate; return current;
