jdk.net.InetSocketAddress — clojure-interop/java.net 1.0.0

This class implements an IP Socket Address (IP address port number) It can also be a pair (hostname port number), in which case an attempt will be made to resolve the hostname. If resolution fails then the address is said to be unresolved but can still be used on some circumstances like connecting through a proxy.

It provides an immutable object used by sockets for binding, connecting, or as returned values.

The wildcard is a special local IP address. It usually means any and can only be used for bind operations.

*create-unresolved clj

(*create-unresolved host port)

Creates an unresolved socket address from a hostname and a port number.

No attempt will be made to resolve the hostname into an InetAddress. The address will be flagged as unresolved.

A valid port value is between 0 and 65535. A port number of zero will let the system pick up an ephemeral port in a bind operation.

host - the Host name - java.lang.String port - The port number - int

returns: a InetSocketAddress representing the unresolved socket address - java.net.InetSocketAddress

throws: java.lang.IllegalArgumentException - if the port parameter is outside the range of valid port values, or if the hostname parameter is null.

->inet-socket-address clj

(->inet-socket-address port)

(->inet-socket-address addr port)

Constructor.

Creates a socket address from an IP address and a port number.

A valid port value is between 0 and 65535. A port number of zero will let the system pick up an ephemeral port in a bind operation.

A null address will assign the wildcard address.

addr - The IP address - java.net.InetAddress port - The port number - int

throws: java.lang.IllegalArgumentException - if the port parameter is outside the specified range of valid port values.

equals clj

(equals this obj)

Compares this object against the specified object. The result is true if and only if the argument is not null and it represents the same address as this object.

Two instances of InetSocketAddress represent the same address if both the InetAddresses (or hostnames if it is unresolved) and port numbers are equal. If both addresses are unresolved, then the hostname and the port number are compared.

Note: Hostnames are case insensitive. e.g. FooBar and foobar are considered equal.

obj - the object to compare against. - java.lang.Object

returns: true if the objects are the same; false otherwise. - boolean

get-address clj

(get-address this)

Gets the InetAddress.

returns: the InetAdress or null if it is unresolved. - java.net.InetAddress

get-host-name clj

(get-host-name this)

Gets the hostname. Note: This method may trigger a name service reverse lookup if the address was created with a literal IP address.

returns: the hostname part of the address. - java.lang.String

get-host-string clj

(get-host-string this)

Returns the hostname, or the String form of the address if it doesn't have a hostname (it was created using a literal). This has the benefit of not attempting a reverse lookup.

returns: the hostname, or String representation of the address. - java.lang.String

get-port clj

(get-port this)

Gets the port number.

returns: the port number. - int

hash-code clj

(hash-code this)

Returns a hashcode for this socket address.

returns: a hash code value for this socket address. - int

to-string clj

(to-string this)

Constructs a string representation of this InetSocketAddress. This String is constructed by calling toString() on the InetAddress and concatenating the port number (with a colon). If the address is unresolved then the part before the colon will only contain the hostname.

returns: a string representation of this object. - java.lang.String

unresolved? clj

(unresolved? this)

Checks whether the address has been resolved or not.

returns: true if the hostname couldn't be resolved into an InetAddress. - boolean
