Method Detail

getInstance

public static NetworkPortRange getInstance(String value)
                                    throws IllegalArgumentException

Creates an instance of PortRange based on the given value.

Parameters:

value - a String representing the range, that may be null or empty for unlimited range, or a valid port range as defined by appendix A.2 for IP address and DNS name.

Returns:

a new PortRange

Throws:

IllegalArgumentException - if the port range syntax is not: portnumber | "-"portnumber | portnumber"-"[portnumber]; or one of the portnumber values is not a valid decimal number in the interval [0, 65535]

getLowerBound

public int getLowerBound()

Returns the lower-bound port value. If the range is not lower-bound, then this returns UNBOUND. If the range is actually a single port number, then this returns the same value as getUpperBound.

Returns:

the upper-bound

getUpperBound

public int getUpperBound()

Returns the upper-bound port value. If the range is not upper-bound, then this returns UNBOUND. If the range is actually a single port number, then this returns the same value as getLowerBound.

Returns:

the upper-bound

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Returns true if the input is an instance of this class and if its value equals the value contained in this class.

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
