public Class SshdSocketAddress

Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

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

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters

o:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

@Override

Returns:List<InetAddress>

a List of local network addresses which are not multicast or localhost sorted according to BY_HOST_ADDRESS

Returns the first external network address assigned to this machine or null if one is not found.

Returns:InetAddress

Inet4Address associated with an external interface DevNote: We actually return InetAddress here, as Inet4Addresses are final and cannot be mocked.

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

Returns:int

a hash code value for this object

Parameters

addr:String

The address to be checked

Returns:boolean

true if the address is in the 100.64.0.0/10 range

See Also

RFC6598

Parameters

addr:InetAddress

The InetAddress to be considered

Returns:boolean

true if the address is a loopback one

Note

if InetAddress#isLoopbackAddress() returns false the address string is checked

See Also

toAddressString(InetAddress), isLoopback(String)

Parameters

ip:String

IP value to be tested

Returns:boolean

true if the IP is "localhost" or "127.x.x.x".

Checks if the address is one of the allocated private blocks

Parameters

addr:String

The address string

Returns:boolean

true if this is one of the allocated private blocks

Note

it assumes that the address string is indeed an IPv4 address

See Also

isIPv4Address(String), PRIVATE_CLASS_A_PREFIX, PRIVATE_CLASS_B_PREFIX, PRIVATE_CLASS_C_PREFIX, Wiki page

Parameters

addr:InetAddress

The InetAddress to be verified

Returns:boolean

true if the address is:

• Not null
• An Inet4Address
• Not link local
• Not a multicast
• Not a loopback

See Also

InetAddress#isLinkLocalAddress(), InetAddress#isMulticastAddress()

Checks if the provided argument is a valid IPv4 address component:

• Not null/empty
• Has at most 3 digits
• Its value is ≤ 255

Parameters

c:CharSequence

The CharSequence to be validate

Returns:boolean

true if valid IPv4 address component

Attempts to resolve the port value

Parameters

addr:SocketAddress

The SocketAddress to examine

Returns:int

The associated port value - negative if failed to resolve

Converts a SocketAddress into an InetSocketAddress if possible:

• If already an InetSocketAddress then cast it as such
• If an SshdSocketAddress then invoke toInetSocketAddress()
• Otherwise, throw an exception

Parameters

remoteAddress:SocketAddress

The SocketAddress - ignored if null

Returns:InetSocketAddress

The InetSocketAddress instance

Exceptions

ClassCastException:

if argument is not already an InetSocketAddress or a SshdSocketAddress

Overrides java.lang.Object.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object. Satisfying this method's contract implies a non-null result must be returned.

Returns:String

a string representation of the object
