Method Detail

encode

public String encode()

Return the host name in encoded form.

Specified by:

encode in class GenericObject

Returns:

String

encode

public StringBuilder encode(StringBuilder buffer)

Description copied from class: GenericObject

Put the encoded version of this object in the given StringBuilder.

Overrides:

encode in class GenericObject

Returns:

boolean

getHostname

public String getHostname()

get the HostName field

Returns:

String

getAddress

public String getAddress()

get the Address field

Returns:

String

getIpAddress

public String getIpAddress()

Convenience function to get the raw IP destination address of a SIP message as a String.

Returns:

String

setHostname

public void setHostname(String h)

Set the hostname member.

Parameters:

h - String to set

setHostAddress

public void setHostAddress(String address)

Set the IP Address.

Returns:

true if the hostname is a DNS name

isIPAddress

public boolean isIPAddress()

Return true if the address is a DNS host name (and not an IPV4 address)

Returns:

true if the hostname is host address.

getInetAddress
