Checks whether another set of service quality attributes is compatible with this set.
o clearAttribute(int)
Clears a given service quality attribute.
o getAttribute(int)
Returns the service mode for a given service quality attribute.
o getLabel(int)
Get the text label for an indexed service quality attribute.
o setAttribute(int, int)

Variables

o DONTCARE 
 public static final int DONTCARE
This mode value indicates that a given service quality attribute can be either enabled or disabled.

This mode value indicates that a given service quality attribute is or must be enabled.

o DISABLED

Constructors

o ServiceQuality 
 public ServiceQuality(int attributeCount,
                       String s[])
Initialises a set of service quality attributes to the "don't care" state. Sets the text label for a given service quality attribute.

Parameters:
attributeCount - The total number of service attributes that can be set for the service.
s - The array of strings to be set.

Methods

o getLabel 
 public String getLabel(int i)
Get the text label for an indexed service quality attribute.

Parameters:
i - The indentifier of the attribute.
o setAttribute 
 public void setAttribute(int attribute,
                          int mode)
Sets the mode for a given service quality attribute. The mode must be ENABLED, DISABLED or DONTCARE.

Parameters:
attribute - The identifier of the attribute to be set.
mode - The service mode for this service attribute.
o clearAttribute 
 public void clearAttribute(int attribute)
Clears a given service quality attribute. This is equivalent to setting the mode of this attribute to DONTCARE.

Parameters:
attribute - The identifier of the attribute to be cleared.
o getAttribute 
 public int getAttribute(int attribute)
Returns the service mode for a given service quality attribute.

Returns:
The service mode for the service quality attribute.
o checkCompatibility 
 public abstract boolean checkCompatibility(ServiceQuality qos)
Checks whether another set of service quality attributes is compatible with this set. A minimal requirement for two sets of quality attributes to be compatible is that one set specifies a given attribute as "enabled" while another specifies it as "disabled". Additional requirements might also be imposed as a consequence of dependencies between different attributes.

Parameters:
qos - A set of service quality attributes.
Returns:
true if the two sets of service quality attributes are compatible.
