value - the value to lookup.
true if the range contains the specified value.
public boolean intersects(double b0,
double b1)
true if the range intersects with the specified
range, and false otherwise.
b0 - the lower bound (should be <= b1).b1 - the upper bound (should be >= b0).
public boolean intersects(Range range)
true if the range intersects with the specified
range, and false otherwise.
range - another range (null not permitted).
public double constrain(double value)
value - the value.
public static Range combine(Range range1,
Range range2)
Note that:
null, in which case the other
range is returned;null the return value is
null.
range1 - the first range (null permitted).range2 - the second range (null permitted).
null).
public static Range expandToInclude(Range range,
double value)
range AND the specified value.
range - the range (null permitted).value - the value that must be included.
public static Range expand(Range range,
double lowerMargin,
double upperMargin)
range - the range (null not permitted).lowerMargin - the lower margin (expressed as a percentage of the
range length).upperMargin - the upper margin (expressed as a percentage of the
range length).
public static Range shift(Range base,
double delta)
base - the base range (null not permitted).delta - the shift amount.
public static Range shift(Range base,
double delta,
boolean allowZeroCrossing)
base - the base range (null not permitted).delta - the shift amount.allowZeroCrossing - a flag that determines whether or not the
bounds of the range are allowed to cross
zero after adjustment.
