Constructor Detail

DoubleRange

public DoubleRange(double number)

Constructs a new DoubleRange using the specified number as both the minimum and maximum in this range.

Parameters:

number - the number to use for this range

Throws:

java.lang.IllegalArgumentException - if the number is NaN

DoubleRange

public DoubleRange(java.lang.Number number)

Constructs a new DoubleRange using the specified number as both the minimum and maximum in this range.

Parameters:

number - the number to use for this range, must not be null

Throws:

java.lang.IllegalArgumentException - if the number is null

java.lang.IllegalArgumentException - if the number is NaN

DoubleRange

public DoubleRange(double number1,
                   double number2)

Constructs a new DoubleRange with the specified minimum and maximum numbers (both inclusive).

The arguments may be passed in the order (min,max) or (max,min). The getMinimum and getMaximum methods will return the correct values.

Parameters:

number1 - first number that defines the edge of the range, inclusive

number2 - second number that defines the edge of the range, inclusive

Throws:

java.lang.IllegalArgumentException - if either number is NaN

DoubleRange

public DoubleRange(java.lang.Number number1,
                   java.lang.Number number2)

Constructs a new DoubleRange with the specified minimum and maximum numbers (both inclusive).

The arguments may be passed in the order (min,max) or (max,min). The getMinimum and getMaximum methods will return the correct values.

Parameters:

number1 - first number that defines the edge of the range, inclusive

number2 - second number that defines the edge of the range, inclusive

Throws:

java.lang.IllegalArgumentException - if either number is null

java.lang.IllegalArgumentException - if either number is NaN
