Constructor Detail
NumberRange
public NumberRange(Number num)(Code)

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


Parameters:
  num - the number to use for this range
throws:
  NullPointerException - if the number is null



NumberRange
public NumberRange(Number min, Number max)(Code)

Constructs a new NumberRange with the specified minimum and maximum numbers.

If the maximum is less than the minimum, the range will be constructed from the minimum value to the minimum value, not what you would expect!.


Parameters:
  min - the minimum number in this range
Parameters:
  max - the maximum number in this range
throws:
  NullPointerException - if either the minimum or maximum number isnull




Method Detail
equals
public boolean equals(Object obj)(Code)

Indicates whether some other Object is "equal" to this one.


Parameters:
  obj - the reference object with which to compare true if this object is the same as the objargument; false otherwise



getMaximum
public Number getMaximum()(Code)

Returns the maximum number in this range.

the maximum number in this range



getMinimum
public Number getMinimum()(Code)

Returns the minimum number in this range.

the minimum number in this range



hashCode
public int hashCode()(Code)

Returns a hash code value for this object.

a hash code value for this object



includesNumber
public boolean includesNumber(Number number)(Code)

Tests whether the specified number occurs within this range using double comparison.


Parameters:
  number - the number to test true if the specified number occurs within thisrange; otherwise, false



includesRange
public boolean includesRange(NumberRange range)(Code)

Tests whether the specified range occurs entirely within this range using double comparison.


Parameters:
  range - the range to test true if the specified range occurs entirely withinthis range; otherwise, false



overlaps
public boolean overlaps(NumberRange range)(Code)

Tests whether the specified range overlaps with this range using double comparison.


Parameters:
  range - the range to test true if the specified range overlaps with thisrange; otherwise, false



toString
public String toString()(Code)

Returns the string representation of this range.

This string is the string representation of the minimum and maximum numbers in the range, separated by a hyphen. If a number is negative, then it is enclosed in parentheses.
