Method Detail

parse

public static SRV parse(DataInputStream dis,
                        byte[] data)
                 throws IOException

Throws:

IOException

isServiceAvailable

public boolean isServiceAvailable()

Check if the service is available at this domain. This checks f the target points to the root label. As per RFC 2782 the service is decidedly not available if there is only a single SRV answer pointing to the root label. From RFC 2782:

A Target of "." means that the service is decidedly not available at this domain.

Returns:

true if the service is available at this domain.

serialize

public void serialize(DataOutputStream dos)
               throws IOException

Description copied from class: Data

The internal method used to serialize Data subclasses.

Specified by:

serialize in class Data

Parameters:

dos - the output stream to serialize to.

Throws:

IOException - if an I/O error occurs.

toString

public String toString()

Overrides:

toString in class Object

getType

public Record.TYPE getType()

Description copied from class: Data

The payload type.

Specified by:

getType in class Data

Returns:

The payload type.

compareTo

public int compareTo(SRV other)

Specified by:

compareTo in interface Comparable<SRV>
