getType

public abstract String getType()

Returns the KNX address type, identifying a group or individual address.

Returns:

address type as string

getRawAddress

public final int getRawAddress()

Returns the KNX address in 16 Bit value representation.

Returns:

the 16 Bit address value

save

public void save(XMLWriter w)
          throws KNXMLException

Writes the KNX address in XML format to the supplied writer.

Parameters:

w - a XML writer
