Method Detail

remove

public static boolean remove(Hub thisHub,
                             Object obj)

remove

public static boolean remove(Hub thisHub,
                             int pos)

remove

protected static boolean remove(Hub thisHub,
                                int pos,
                                boolean bForce)

remove

public static boolean remove(Hub thisHub,
                             Object obj,
                             boolean bForce,
                             boolean bSendEvent,
                             boolean bDeleting,
                             boolean bSetAO,
                             boolean bSetPropToMaster,
                             boolean bIsRemovingAll)

canRemove

public static boolean canRemove(Hub thisHub,
                                Object obj)

clear

public static void clear(Hub thisHub)

clear

public static void clear(Hub thisHub,
                         boolean bSetAOtoNull,
                         boolean bSendNewList)

canAdd

public static boolean canAdd(Hub thisHub,
                             Object obj)

Used to find out if an object can be added/inserted to this Hub. Makes sure that object that being added is for the correct class. Calls all HubListeners.hubBeforeAdd() where HubEvent.object and pos are both set. If objects are OAObjets, then canAdd is called for each object. If it is a recursive Hub, then it will verify that it can have the parent set.

canAddMsg

public static String canAddMsg(Hub thisHub,
                               Object obj)

add

public static void add(Hub thisHub,
                       Object obj)

internalAdd

protected static boolean internalAdd(Hub thisHub,
                                     Object obj,
                                     boolean bHasLock,
                                     boolean bCheckContains)

internal method to add to vector and hashtable

sortMove

protected static void sortMove(Hub thisHub,
                               Object obj)

move

protected static void move(Hub thisHub,
                           int posFrom,
                           int posTo)

Swap the position of two different objects within the hub. This will call the move method. Sends a hubMove event to all HubListeners.

Parameters:

posFrom - position of object to move

posTo - position where object should be after the move

insert

public static boolean insert(Hub thisHub,
                             Object obj,
                             int pos)

Insert an Object at a position. Hub Listeners will be notified with an insert event.

If Hub is sorted, then object will be inserted at correct/sorted position.

Parameters:

obj - Object to insert, must be from the same class that was used when creating the Hub

pos - position to insert the object into the Hub. If greater then size of Hub, then it will be added to the end.

Returns:

true if object was added else false (event hubBeforeAdd() threw an exception)

swap

public static void swap(Hub thisHub,
                        int pos1,
                        int pos2)

Swap the position of two different objects within the hub. This will call the move method.

Parameters:

pos1 - position of object to move from, if there is not an object at this position, then no move is performed.

pos2 - position of object to move to, if there is not an object at this position, then no move is performed.

getAddedObjects

public static OAObject[] getAddedObjects(Hub thisHub)

getRemovedObjects

public static OAObject[] getRemovedObjects(Hub thisHub)

isAllowAddRemove

public static boolean isAllowAddRemove(Hub thisHub)

unsafeAddAll

public static void unsafeAddAll(Hub hub,
                                List list)

This will load all of the objects into the hub without checking or sending events.

refresh

public static void refresh(Hub hub,
                           Hub hubNew)
