Method Detail

getHost

public String getHost()

Get the host (hostname or IP address).

Returns:

hostname of the peer

getPort

public int getPort()

Get the port of the host.

Returns:

port of the remote peer

getResourceName

public String getResourceName()

Get the resource name, that is the name of the remote websocket endpoint.

Returns:

the request-URI of the remote endpoint

isSecure

public boolean isSecure()

Tell if the websocket is secured or not.

Returns:

true is this URI is intended to be create a secured connection (wss://); false otherwise (ws://)

toString

public String toString()

Description copied from class: Object

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Overrides:

toString in class Object

Returns:

a string representation of the object.
