Constructor Detail

IntRange

public IntRange(int number)

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

Parameters:
number - the number to use for this range

IntRange

public IntRange(java.lang.Number number)

Constructs a new IntRange 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

IntRange

public IntRange(int number1,
                int number2)

Constructs a new IntRange 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

IntRange

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

Constructs a new IntRange 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
Method Detail

getMinimumNumber

public java.lang.Number getMinimumNumber()

Returns the minimum number in this range.

Specified by:
getMinimumNumber in class Range
Returns:
the minimum number in this range

getMinimumLong

public long getMinimumLong()

Gets the minimum number in this range as a long.

Overrides:
getMinimumLong in class Range
Returns:
the minimum number in this range

getMinimumInteger

public int getMinimumInteger()

Gets the minimum number in this range as a int.

Overrides:
getMinimumInteger in class Range
Returns:
the minimum number in this range

getMinimumDouble

public double getMinimumDouble()

Gets the minimum number in this range as a double.

Overrides:
getMinimumDouble in class Range
Returns:
the minimum number in this range

getMinimumFloat

public float getMinimumFloat()

Gets the minimum number in this range as a float.

Overrides:
getMinimumFloat in class Range
Returns:
the minimum number in this range

getMaximumNumber

public java.lang.Number getMaximumNumber()

Returns the maximum number in this range.

Specified by:
getMaximumNumber in class Range
Returns:
the maximum number in this range

getMaximumLong

public long getMaximumLong()

Gets the maximum number in this range as a long.

Overrides:
getMaximumLong in class Range
Returns:

containsNumber

public boolean containsNumber(java.lang.Number number)

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

null is handled and returns false.

Specified by:
containsNumber in class Range
Parameters:
number - the number to test, may be null
Returns:
true if the specified number occurs within this range

containsInteger

public boolean containsInteger(int value)

Tests whether the specified int occurs within this range using int comparison.

This implementation overrides the superclass for performance as it is the most common case.

Overrides:
containsInteger in class Range
Parameters:
value - the int to test
Returns:
true if the specified number occurs within this range by int comparison

containsRange

public boolean containsRange(Range range)

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

null is handled and returns false.

Overrides:
containsRange in class Range
Parameters:
range - the range to test, may be null

true if the specified range occurs entirely within this range
Throws:
java.lang.IllegalArgumentException - if the range is not of this type

overlapsRange

public boolean overlapsRange(Range range)

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

null is handled and returns false.

Overrides:
overlapsRange in class Range
Parameters:
range - the range to test, may be null
Returns:
true if the specified range overlaps with this range

equals

public boolean equals(java.lang.Object obj)

Compares this range to another object to test if they are equal.

.

To be equal, the class, minimum and maximum must be equal.

Overrides:
equals in class Range
Parameters:
obj - the reference object with which to compare
Returns:
true if this object is equal

hashCode

public int hashCode()

Gets a hashCode for the range.

Overrides:
hashCode in class Range
Returns:
a hash code value for this object

toString

public java.lang.String toString()

Gets the range as a String.

The format of the String is 'Range[min,max]'.

Overrides:
toString in class Range
Returns:
the String representation of this range

toArray

public int[] toArray()

Returns an array containing all the integer values in the range.

Returns:
the int[] representation of this range
