    Title: Selection by track number
    Nature: Enhancement
    Severity: Significant

    The ways to select by track number as well as to select within geographic geometry seem to me inefficient. Indeed, in that way there are 2 accesses to the TACSIT server(s): one to query on one to effectively select when an interface proposing to select from a an interface with a query as parameter would be more efficient since it implied just one access call to the TACSIT server.

    This API seems to me very poor. Wouldn't it be possible to add some convenience APIs allowing a listener on the primary selection, the secondary selection, on setting or unsetting on of these selection... This would lower the number of server-client exchanges for nothing but test that this not something of interest.

Consistent centring with a moving entity

  • Summary:

    The proposed way to do the consistent centring with a moving entity seems inefficient and will imply unsmooth multiple movements of the viewport.
    A specific interface allowing such a slaved centring with an entity would be, in my point of view, by far better than this.

Add an EntityRepository Concept / Class to the Standard

  • Key: TCI11-26
  • Legacy Issue Number: 17006
  • Status: open  
  • Source: SimVentions ( Mr. Matthew Wilson)
  • Summary:

    The definition of how Entity objects are related to and move around through a TacsitController, ViewportManager, and Viewport seems to be vague by design. Presumably, vendors have different implementations that make creating a cohesive abstraction difficult. It is a worthy goal, however – if it can be achieved. Separating the subsystems into more clearly defined subcomponents (Track providing, and track viewing) promotes encapsulation and division of responsibility. It also allows simplified compliance to the Tacsit specification for implementations which really provide only a single subsystem.

    Consider NASA’s Worldwind. It is a general geographic map package. It provides little facility for getting track information from remote sources. The entire entity store concept is foreign to Worldwind; the reference implementation is purely incidental. Worldwind could work with any entity store, provided it had a well defined interface.

    The reference implementation contains a sample of what an EntityRepository would look like. The definition is given here (sans comments):

    public interface EntityRepository<E extends Entity> extends QueryManager

    { public Iterator<E> getEntities(); public void addRepositoryListener(RepositoryListener listener); public void removeRepositoryListener(RepositoryListener listener); }

    Repository Listener would be defined as follows:

    public interface RepositoryListener

    { public void entitiesAdded(RepositoryChangeEvent event); public void entitiesRemoved(RepositoryChangeEvent event); public void entitiesUpdated(RepositoryChangeEvent event); public void entitiesCleared(RepositoryChangeEvent event); }

    This interface description should be general enough to allow for abstraction of existing implementations.

    An area of common concern for this type of implementation is update speed. If data is being imported at a very fast speed, the user interface may not be able to handle the volume of updates. For instance, consider the common scenario that each update received is an array of structs containing track data that contains all the values for the track in the system. If a repository were to fire an “entitiesUpdated” event every time a property was copied into the entity, that would potentially be many new objects created:

    O = (number of objects created to fire the event) *(number of properties set) * (number of tracks)

    Each track will probably have 10 properties, 2 objects will be needed, and there may be roughly 2000 tracks in the system. That’s 40,000 objects every time a new track block comes in – excluding anything that happens once it gets to the UI.

    However, this problem can be alleviated by deviating slightly from the standard Listener implementation. Instead of broadcasting to a RepositoryListener any time a track is changed, the EntityRepository can poll its Entity objects for changes based on an update rate. It would then fire a summary of those changes to its associated listeners, effectively coalescing all the redundant events into a single one. This drastically cuts down on the number of objects created to:

    O = (number of objects created to fire the event)

    Each entity will need to be “polled” every update, but the polling consists simply of checking a time value against a known value. In the example above, 2000 lastModified values would have to be compared.

    This allows the update interval to be easily scaled to the fastest possible rate that still gives the desired responsiveness in the user interface. The key attribute is this: from the perspective of the client of the entity repository interface, it behaves exactly as per a “normal” Listening pattern. The complexity is masked by the interface and doesn’t creep into client code.

    An example of how such an implementation would work is included in the reference implementation, PolledEntityRepository.

Add an Angle Class to the Standard

  • Key: TCI11-32
  • Legacy Issue Number: 17004
  • Status: open  
  • Source: SimVentions ( Mr. Matthew Wilson)
  • Summary:

    Having an Angle class would be very useful. This would free you from potential errors about worrying whether a double represents degrees or radians. This worry is particularly troublesome, since interface components present angles as degrees, whereas processing is most frequently done in radians. When dealing with unstructured primitive values, it’s an easy mistake to make. An Angle class would allow both to operate in whatever unit was most convenient by providing getters for each unit type.

    In addition to unit safety checking, it also makes property editors (for example, for tables and forms) far simpler to construct. The simplest way to specify an editor or renderer is to set the default cell editor or renderer. This facilitates minimal coupling between UI implementations and the data being presented. If the data is stored and presented as doubles, this approach is not possible because an editor that works for a unit of distance is probably not appropriate to also work for a unit of angle. Since GeodeticPosition contains both, this problem is likely to come up very frequently. The problem can be worked around by explicitly setting a particular column’s editor or renderer, but this strongly couples the display capability to the ordering of the displayed TableModel.

    A sample implementation of Angle is provided in the reference implementation. If Angle is added, the following properties should be changed to an Angle:
    • Rectangle
    o Orientation property
    • Geodetic Position
    o Latitude property
    o Longitude property
    • ViewEyeProperties
    o Orientation property

Add a Distance Class to the Standard

  • Key: TCI11-31
  • Legacy Issue Number: 17005
  • Status: open  
  • Source: SimVentions ( Mr. Matthew Wilson)
  • Summary:

    Using this as an object rather than a plain double value is a cheap way to avoid costly errors. NASA lost a $125 million Mars orbiter because one team was using imperial units instead of metric. Representing distance as an object makes it glaringly obvious in the code which calculations are using which units.

    Consider the following method of Rectangle:
    double getHeight();

    Embedded in the comments of the interface contract is that “getHeight()” returns a double in meters. But that’s not at all obvious in client code that uses getHeight(), especially if it’s 2 or 3 levels removed from the place it is called.
    Instead, if it were changed to:
    Distance getHeight();

    Distance could have methods “double getMeters()”, and “double getFeet()”, that make it immediately obvious what the returned value represents.

    If adopted, the following changes should be made:
    • GeodeticPosition
    o Change altitude property from double to Distance
    • Rectangle
    o Change getHeight() to return Distance
    o Change getWidth() to return Distance
    • Circle
    o Change getRadius() to return Distance
    • ViewEyeProperties
    o Change get/setRangeScale to use Distance
    • Viewport
    o Change scaleToPoints(points, margin) margin parameter to Distance

Add method to Entity interface to “getReferencePoint

  • Key: TCI11-30
  • Legacy Issue Number: 17008
  • Status: open  
  • Source: SimVentions ( Mr. Matthew Wilson)
  • Summary:

    There is no way to get even a general understanding about where an Entity exists at a general interface level.

    Suggested Resolution:
    Define a new method in the entity interface:

    GeodeticPosition getReferencePoint();

    This is logically consistent across any entity type. An entity could still consist of multiple points (e.g., isPointEntity() would return false), and still return a center point. This keeps the conceptual integrity of the entity interface, but expands its utility.

    One such concrete example of the utility: Creating a user interface component for scaling a Viewport to a set of points. The most common use case is for those points to be entity positions. The QueryManager can be used to retrieve a list of entities, but from that point on you have to dive into implementation specific details to convert the Entities to a position to choose from.

    One such concrete example of the utility: Creating a user interface component for scaling a Viewport to a set of points. The most common use case is for those points to be entity positions. The QueryManager can be used to retrieve a list of entities, but from that point on you have to dive into implementation specific details to convert the Entities to a position to choose from.

    Revised Text:
    Part of this resolution is the editorial fix to clean up the “extra” tables in 7.1.1.1.3.

    Update the model to reflect the new method in the Entity interface to add getReferencePoint() with a return type of GeodeticPosition.

    Add a new section to the specification and update the graphic in paragraph 7.1.1.1 on figure 7.11to reflect the new method.

    7.1.1.1.5 getReferencePoint
    Returns the GeodeticPosition to be used as the main point of reference for this entity.
    Type GeodeticPosition

    Is Abstract false

  • Summary:

    Severity: Support Text

    Summary: The comments of this class reference state this:

    Containment is determined by using the Entity's Geometry as an argument to the contains() method on the Geometry specified by this Query, i.e., this.satisfies( entity ) = this.getGeometry().contains( entity.getGeometry() )

    This is not possible, however. The entity class has no “Geometry” in its interface. If it were present, the Geometry interface does not provide enough information to evaluate such a query.

    Resolution:
    The Geometry class “contains” method accepts a GeodeticPosition, not a Geometry. By adding the “getReferencePoint” method to entity (as proposed by issue XXXX) and modifying the comment on this method

    Change the comment to a more accurate description of how to use it. For example: Containment is determined by checking whether or not an entity’s reference point (GeodeticPosition) is contained within a specific Geometry, i.e. this.satisfies(entity) = this.getGeometry().contains(entity.getReferencePoint()).

    Revised Text:
    Section 7.2.1.1 changed the description / comment for the method to
    “Containment is determined by checking whether or not an entity’s reference point (GeodeticPosition) is contained within a specific Geometry, i.e. this.satisfies(entity) = this.getGeometry().contains(entity.getReferencePoint()).”

Remove “plural” designation of method call in EntityTypeQuery

  • Key: TCI11-14

  • Status: open  
  • Source: SimVentions ( Mr. Matthew Wilson)
  • Summary:

    Summary:
    Interface specification is pluralized and the figure on 7.2.1.3 shows a return of multiple EntityType objects. This implies that multiple EntityTypes are returned, however, the return value specified in the table and the Java PSM is singular.

    EntityType getEntityTypes( );

    Resolution / Discussion:
    Change the return type in the table to match the model and update the Java PSM.

    The Java PSM will return a Collection<EntityType> instead of a single EntityType object.

    Revised Text:

    In Paragraph 7.2.1.3.1, modify the table to:

Add a Distance Class to the Standard

  • Key: TCI11-17
  • Legacy Issue Number: 17053
  • Status: open  
  • Source: SimVentions ( Mr. Matthew Wilson)
  • Summary:

    Using this as an object rather than a plain double value is a cheap way to avoid costly errors. NASA lost a $125 million Mars orbiter because one team was using imperial units instead of metric. Representing distance as an object makes it glaringly obvious in the code which calculations are using which units.

    Consider the following method of Rectangle:
    double getHeight();

    Embedded in the comments of the interface contract is that “getHeight()” returns a double in meters. But that’s not at all obvious in client code that uses getHeight(), especially if it’s 2 or 3 levels removed from the place it is called.
    Instead, if it were changed to:
    Distance getHeight();

    Distance could have methods “double getMeters()”, and “double getFeet()”, that make it immediately obvious what the returned value represents.

    If adopted, the following changes should be made:
    • GeodeticPosition
    o Change altitude property from double to Distance
    • Rectangle
    o Change getHeight() to return Distance
    o Change getWidth() to return Distance
    • Circle
    o Change getRadius() to return Distance
    • ViewEyeProperties
    o Change get/setRangeScale to use Distance
    • Viewport
    o Change scaleToPoints(points, margin) margin parameter to Distance
    Resolution:

    A Distance class has been added to the specification and referenced in the places suggested.
