Direct Known Subclasses:

Location

public abstract class AbsLocation
extends ComparableIndividual

A very abstract representation of locations just at a level needed by the middleware. It is considered as crucial that in the realization of the brokerage mechanisms, location is used as one of the non-functional parameters for selecting a server or a client, e.g. being placed in a location or having the smallest distance to a location. By defining Location as a subclass of ComparableIndividual we are implicitly defining a transitional property 'is in' with the following semantic:

• loc₁ < loc₂ ⇒ loc₁ is in loc₂
• loc₁ > loc₂ ⇒ loc₂ is in loc₁
• loc₁ = loc₂ ⇒ both of the above are true

However, it should be clear that not all locations are comparable with each other; this implies that 'is in' defines just a partial order between locations.

Field Detail

MY_URI

public static final String MY_URI

The URI of the ontology class.

Constant Field Values

Constructor Detail

AbsLocation

protected AbsLocation(String uri)

Create an abstract location.

Parameters:

uri - URI of the location.

AbsLocation

protected AbsLocation()

Constructor just for usage by de-serializers. Do not use this constructor within applications as it may lead to incomplete instances that cause exceptions.

Method Detail

getClassURI

public String getClassURI()

Description copied from class: ManagedIndividual

Get the class URI for this ManagedIndividual. All non-abstract subclasses MUST overwrite this method!

Overrides:

getClassURI in class ComparableIndividual

Returns:

The class URI.

See Also:

ManagedIndividual.getClassURI()

getDistanceTo

public abstract float getDistanceTo(AbsLocation other)

Returns the distance (meters) between the current location and the argument location.
