      gov.nasa.arc.brahms.common.rt.ConceptCtx
          gov.nasa.arc.brahms.common.rt.ActiveInstanceCtx
              gov.nasa.arc.brahms.common.rt.ObjectInstanceCtx

All Implemented Interfaces:

IActiveInstanceCtx, IBrahmsObjectCtx, IConceptCtx, IObjectInstanceCtx, IRuntimeConstants, java.io.Serializable

public class ObjectInstanceCtx
extends ActiveInstanceCtx
implements IObjectInstanceCtx

The ObjectInstanceCtx is the runtime class for the objects. It manages the belief set, location, frame contexts with their various states and containment. The virtual machine maintains the object states through the object instance contexts.

Constructor Detail

ObjectInstanceCtx

public ObjectInstanceCtx(ObjectInstance obj)

Constructor, creates a new context for the specified ObjectInstance.

Parameters:

obj - the ObjectInstance for which to create a context

Method Detail

addAggregate

public void addAggregate(PartCtx aggregate)
                  throws gov.nasa.arc.brahms.common.exceptions.BrahmsException

Adds the specified aggregate as an aggregate for this object instance. The actual aggregate is the part context's aggregate/parent. Aggregates and sub aggregates are associated through a PartCtx.

Specified by:

addAggregate in interface IObjectInstanceCtx

Parameters:

aggregate - the aggregate (PartCtx) to be added

Throws:

gov.nasa.arc.brahms.common.exceptions.BrahmsException - if aggregate is null

removeAggregate

public void removeAggregate(PartCtx aggregate)
                     throws gov.nasa.arc.brahms.common.exceptions.BrahmsException

Removes the specified aggregate as an aggregate for this object instance. The actual aggregate is the part context's aggregate/parent. Aggregates and sub aggregates are associated through a PartCtx.

Specified by:

removeAggregate in interface IObjectInstanceCtx

Parameters:

aggregate - the aggregate to be removed

Throws:

gov.nasa.arc.brahms.common.exceptions.BrahmsException - if aggregate is null, no aggregates are available, or the aggregate is not found

getAggregates

public java.util.Enumeration getAggregates()
                                    throws gov.nasa.arc.brahms.common.exceptions.BrahmsException

Returns a list of all the aggregates (PartCtx).

Specified by:

getAggregates in interface IObjectInstanceCtx

Returns:

Enumeration an enumeration of PartCtx

Throws:

gov.nasa.arc.brahms.common.exceptions.BrahmsException - if there are no aggregates

removeAllAggregates

public void removeAllAggregates()

Removes all the aggregates from the list of aggregates.

Specified by:

removeAllAggregates in interface IObjectInstanceCtx
