Class MOMHelper

  org.portico.shared.model.MOMHelper

public class MOMHelper
extends Object

This class helps do MOM related stuff (including 1.3/1516 conversions). As a result, it is VERY ugly internally. I can't understand why the IEEE 1516 standards group decided to ENTIRELY BREAK ALL BACKWARDS COMPATIBILITY by prefixing everything with "HLA", but they did. As a result, we have to do all sorts of ugly stuff we wouldn't normally have to do, so get used to it.

getFederateAttributes

public static HashSet<Integer> getFederateAttributes()

getFederationAttributes

public static HashSet<Integer> getFederationAttributes()

getMOMClassHandle

public static int getMOMClassHandle(String className)

Fetch the handle for the MOM class of the given name. This will work when given either HLA 1.3 or HLA 1516 style MOM names. If the class name is unknown, ObjectModel.INVALID_HANDLE will be returned.

getMOMAttributeHandle

public static int getMOMAttributeHandle(int classHandle,
                                        String name)

Fetch the handle for the MOM attribute of the given name in the MOM class of the given handle. If the handle is not recognized or the name isn't a valid attribute, ObjectModel.INVALID_HANDLE will be returned.

strip1516Crap

public static String strip1516Crap(String name)

This method will remove "HLA" from the front of any provided string and return the resulting string. If the next letter is lower case, it will be made upper case. This will work on "." separated names. For example: "HLAobjectRoot.HLAmanager" will become "ObjectRoot.Manager".

insertMomHierarchy

public static void insertMomHierarchy(ObjectModel theModel)

Build the hierarchy of MOM object classes and initialize them with the default handles. This method will also patch the MOM stuff into the model, adding all the classes and setting the manager class (for example) as a child of the object root.

newAttribute

private static ACMetadata newAttribute(String name,
                                       int handle)
