Constructor Detail

PortRange

public PortRange()

Create an empty port range.

PortRange

public PortRange(Set<Integer> rangeSet)

Create a port range including all elements in a set.

Parameters:

rangeSet - the elements of the ranges

Method Detail

createPortRange

public static PortRange createPortRange(String ranges)

This method can be used to create sets containing all the possible values in a multiple partial ranges. Creates a range set from a string in the form: ::= | - | , This is useful when handling port ranges.

Parameters:

ranges - a string with the required format

Returns:

a disjoint range containing all the possible values

size

public int size()

Returns the number of elements in the range.

Returns:

number of elements in this range

contains

public boolean contains(int i)

Returns true if this range contains the specified element.

Parameters:

i - element to be checked for containment in this range

Returns:

true if this range contains the element

getRandomElement

public Integer getRandomElement()

Returns a random element contained by the port range or null if the range is empty.

Returns:

a random element

iterator

public Iterator<Integer> iterator()

Specified by:

iterator in interface Iterable<Integer>
