ICECandidate

public ICECandidate()

ICECandidate

public ICECandidate(String ip,
            int generation,

            String password,
            int port,
            String username,
            int preference,
            ICECandidate.Type type)

Constructor with the basic elements of a transport definition.

Parameters:

ip - the IP address to use as a local address

generation - used to keep track of the candidates

network - used for diagnostics (used when the machine has several NICs)

password - user name, as it is used in ICE

port - the port at the candidate IP address

username - user name, as it is used in ICE

preference - preference for this transportElement, as it is used in ICE

type - type as defined in ICE-12

public String getId()

Get the ID

Returns:

the id

setId

public void setId(String id)

Set the ID

Parameters:

id - the id to set

getProto

public TransportCandidate.Protocol getProto()

Get the protocol used for the transmission

Returns:

the protocol used for transmission

setProto

public void setProto(TransportCandidate.Protocol proto)

Set the protocol for the transmission

Returns:

a username string

getChannel

public TransportCandidate.Channel getChannel()

Get the channel

Returns:

the channel associated

setChannel

public void setChannel(TransportCandidate.Channel channel)

Set the channel for this transportElement

Parameters:

channel - the new channel

setUsername

public void setUsername(String username)

Set the username for this transportElement in ICE

check

public void check(List<TransportCandidate> localCandidates)

Check if a transport candidate is usable. The transport resolver should check if the transport candidate the other endpoint has provided is usable.

ICE Candidate can check connectivity using UDP echo Test.

Overrides:

check in class TransportCandidate

equals

public boolean equals(Object obj)

Overrides:

equals in class TransportCandidate

isNull

public boolean isNull()

Description copied from class: TransportCandidate

Return true if the candidate is not valid.

Overrides:

isNull in class TransportCandidate

Returns:

true if the candidate is null.

compareTo

public int compareTo(ICECandidate arg)

Compare the to other Transport candidate.

Specified by:

compareTo in interface Comparable<ICECandidate>

Parameters:

arg - another Transport candidate

Returns:

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object
