java.lang.Object

org.yamcs.utils.DoubleRange

All Implemented Interfaces:

Serializable

public class DoubleRange
extends Object
implements Serializable

A range of numbers [min, max) where both min and max can be inclusive or exclusive. Both min and max can be Double.NaN meaning that the range is open at that end.

Constructor Detail

DoubleRange

public DoubleRange(double min,
                   double max,
                   boolean minIncl,
                   boolean maxIncl)

DoubleRange

public DoubleRange(double minInclusive,
                   double maxInclusive)

Method Detail

fromXtceComplement

public static DoubleRange fromXtceComplement(double minExclusive,
                                             double maxExclusive,
                                             double minInclusive,
                                             double maxInclusive)

Returns a range from the XTCE float range used for alarms which is in fact a union of two ranges

Parameters:

minExclusive -

maxExclusive -

minInclusive -

maxInclusive -

Returns:

getMax

public double getMax()

getMin

public double getMin()

isMinInclusive

public boolean isMinInclusive()

isMaxInclusive

public boolean isMaxInclusive()

inRange

public int inRange(double v)

Checks if the value is in range.

Parameters:

v -

Returns:

<0 =0 or >0 if the value v is lower than min, between min and max or greater than max respectively.

intersectWith

public DoubleRange intersectWith(DoubleRange other)

E.g. a low limit of ]-Infinity, -22] and a high limit of [40, +Infinity[ intersect to [-22, 40] (which for practical purposes is actually the range inside of which pvals are _not_ out of limits)

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
