Constructor Detail

LongRange

public LongRange(long number)

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

Parameters:

number - the number to use for this range

LongRange

public LongRange(Number number)

Constructs a new LongRange 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:

IllegalArgumentException - if the number is null

LongRange

public LongRange(long number1,
                 long number2)

Constructs a new LongRange 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

LongRange

public LongRange(Number number1,
                 Number number2)

Constructs a new LongRange 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:

IllegalArgumentException - if either number is null

Method Detail

getMinimumNumber

public 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()

the minimum number in this range

getMaximumNumber

public 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:

getMaximumFloat

public float getMaximumFloat()

Gets the maximum number in this range as a float.

This conversion can lose information for large values.

Overrides:

getMaximumFloat in class Range

Returns:

the maximum number in this range

containsNumber

public boolean containsNumber(Number number)

Tests whether the specified number occurs within this range using long 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

containsLong

public boolean containsLong(long value)

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

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

Overrides:

containsLong in class Range

Parameters:

value - the long to test

Returns:

true if the specified number occurs within this range by long comparison

containsRange

public boolean containsRange(Range range)
