Class AbstractLocalWorldView

java.lang.Object
  cz.cuni.amis.pogamut.multi.communication.worldview.impl.AbstractLocalWorldView

All Implemented Interfaces:

IComponent, ILocalWorldView, ITimedWorldChangeEventInput

Direct Known Subclasses:

EventDrivenLocalWorldView

public abstract class AbstractLocalWorldView
extends java.lang.Object
implements ILocalWorldView

WorldView responsible for single agent. The LocalWorldView always knows which timeKey is considered actual to its agent and makes sure, that the objects stay consistent for that timeKey and that newer objects are stored for further use. Abstract worldView handles data management and listener handling.

Returns:

createCompositeObject

protected abstract ICompositeWorldObject createCompositeObject(ILocalWorldObject localObject,
                                                               ISharedWorldObject sharedObject,
                                                               IStaticWorldObject staticObject)

Method used for returning the appropriate CompositeObject type made from the three provided object parts. All parts must share the same WorldObjectId and must belong to the same CompositeObject class. Also, none of the parts may be null.

The method should return a proxy-type CompositeObject, meaning that the object will only wrap all objectParts and no data will actually be copied.

This method must be overriden by a object-awareWorldView which has information about all the object classes in the world and is able to call the correct constructors

Parameters:

localObject - local part of the object

sharedObject - shared part of the object

staticObject - static part of the object

Returns:

Proxy-type compositeObject.

getAgentId

public ITeamedAgentId getAgentId()

Returns agentId of the agent associated with this WorldView.

Specified by:

getAgentId in interface ILocalWorldView

Returns:

teamed AgentId

getLocal

public ILocalWorldObject getLocal(WorldObjectId objectId)

Description copied from interface: ILocalWorldView

Returns the most current LocalObject.
Returns the local part of requested WorldObject. A local part for every object contains properties subjective to only one agent. (like isVisible).

Specified by:

getLocal in interface ILocalWorldView

Returns:

getLocal

protected ILocalWorldObject getLocal(WorldObjectId objectId,
                                     TimeKey time)

Returns the LocalObject associated with the provided TimeKey. Returns the local part of requested WorldObject. A local part for every object contains properties subjective to only one agent. (like isVisible).

Parameters:

objectId -

time -

Returns:

get

protected ICompositeWorldObject get(WorldObjectId objectId,
                                    TimeKey time)

Returns the object actual to the specified TimeKey. Returns the CompositeWorldObject for the requested Id. Composite objects behave like old WorldObjects, they contain all object fields and the data is guaranteed to be consistent (meaning all fields are actual for the same timeKey). Any object returned by this method should be compatible with any non-multi method (ie. a method expecting just IWorldObject).

Parameters:

objectId -

time -

Returns:

Throws:

get

public ICompositeWorldObject get(WorldObjectId objectId)

Specified by:

get in interface ILocalWorldView

Returns:

getAll

protected java.util.Map<java.lang.Class<?>,java.util.Map<WorldObjectId,ICompositeWorldObject>> getAll(TimeKey time)

Returns all objects sorted according to class. All of the classMaps are lazy-implemented, so the CompositeObject will only be created on get method. If you need to iterate over the map, but you don't need the actual objects, iterate over the keySet. Do not hold reference to this map! Always use new getAll() call when you need this map again or you risk that some classMaps will get new timeKeys. By calling getAll(Class, time != thisTime).

Parameters:

time -

Returns:

getAll

public java.util.Map<java.lang.Class<?>,java.util.Map<WorldObjectId,ICompositeWorldObject>> getAll()

Description copied from interface: ILocalWorldView

Returns all objects sorted according to class. All of the classMaps are lazy-implemented, so the CompositeObject will only be created on get method. If you need to iterate over the map, but you don't need the actual objects, iterate over the keySet. Do not hold reference to this map! Always use new getAll() call when you need this map again or you risk that some classMaps will get new timeKeys. By calling getAll(Class, time != thisTime).

Specified by:

getAll in interface ILocalWorldView

Returns:

getAll

protected <T extends ICompositeWorldObject> java.util.Map<WorldObjectId,T> getAll(java.lang.Class<T> type,

Returns a lazy-implemented classMap containing CompositeWorldObjects current to the specified TimeKey.

WARNING : do not store this map, always use the getAll() method or copy the map if you really need it stored somewhere. The TimeKey can be overriden by calling another getAll( Class==Class, time!=time) .

Type Parameters:

T -

Parameters:

type -
