Detailed Description

A scene entity that is being owned and listened to by other scene entities.

ReferenceTarget is the base class for scene entities that allow to be referenced by instances of class ReferenceMaker. Most plugins are derived from this class.

This class exposes methods for sending notification messages to its dependent ReferenceMaker objects, enumerating their dependents, etc.

Note that RefTargetHandle is a typename for pointers to an object of type ReferenceTarget.

Constructor & Destructor Documentation

◆ ~ReferenceTarget()

virtual CoreExport ~ReferenceTarget ( )

protectedpure virtual

Destructor.

Instances of class ReferenceTarget and classes derived from it should be deleted by calling ReferenceTarget::MaybeAutoDelete() or ReferenceMaker::DeleteMe() on them, rather then calling the delete operator. This will ensure that the object drops all references made to it and the references it makes to other objects.

◆ ReferenceTarget()

CoreExport ReferenceTarget ( )

Constructor.

Member Function Documentation

◆ AutoDelete()

virtual CoreExport RefResult AutoDelete ( )

virtual

Deletes the object when it has no more real dependents.

This function is called by 3ds Max in order to delete a plugin object when its last real dependent has been deleted. It also allows derived classes to control the lifetime of their instances. The default implementation of this method will drop the references this object makes to other objects, and if the undo system is engaged (holding) it will ensure that the deletion is undo/redo-able. Override this method only if you don't want instances of your plugin to be automatically deleted when the last reference to them is deleted. Most subclasses of class ReferenceTarget will not need to override this method. Plugins should call ReferenceTarget::MaybeAutoDelete() or ReferenceMaker::DeleteMe() to delete instances of plugin objects. For more information on how 3ds Max deletes reference targets, see ReferenceTarget::MaybeAutoDelete()

Returns: Default implementation always returns REF_SUCCEED. Overwrites should also always return REF_SUCCEED.

Note: Classes that overwrite this method to prevent deletion of their instances, should be deleted by calling ReferenceMaker::DeleteMe() on them.

Reimplemented in MtlLib, and MtlBaseLib.

◆ MaybeAutoDelete()

CoreExport RefResult MaybeAutoDelete ( )

Deletes the object when it has no more real dependents.

The system calls this method to check if it can delete objects that had a reference to them deleted (dropped). If there are no more real dependents on this object, this function will ask the object to auto-delete itself. See ReferenceTarget::AutoDelete() for more information on this. Note that "weak" references will not prevent the deletion of the object. Plugins should also call this method when they need to delete plugin instances. See ReferenceTarget::AutoDelete() for more information on deleting plugin instances.

Returns: REF_SUCCEED if this object was deleted successfully, or REF_FAIL if the object has outstanding real dependents to it and as a result it cannot be deleted.

Note: Objects can prevent their own deletion by overwriting ReferenceTarget::AutoDelete(). Examples of objects that may want to do this are singletons such as class MtlLib.

◆ GetClassName()

CoreExport void GetClassName	(	MSTR &	s,
		bool	localized = `true`
	)		const

overridevirtual

Retrieves the name of the plugin class.

This name is used in 3ds Max's UI and in MAXScript. For Material plug-ins this method is used to put up the material "type" name in the Material Editor.

Parameters

s	Reference to a string filled in with the name of the plugin class.
localized	If true, then the class name returned should be localized in the language 3ds Max is currently using. Otherwise it should be the class name in English. If a plugin does not provide localized string resources, it can disregard this parameter and always return the class name in English.

◆ SuperClassID()

CoreExport SClass_ID SuperClassID ( )

overridevirtual

Retrieves a constant representing the type of the plugin.

Returns: A super class id that uniquely identifies the type (category) of the plugin. Note that several plugin classes can be of the same type, thus return the same super class id. Plugins are uniquely identified by their class ids.

Parameters

dep	- The callback object called for each dependent.

Returns: Return 1 to stop the enumeration and 0 to continue.

See also: EnumRefHierarchy

◆ Clone()

virtual CoreExport RefTargetHandle Clone ( RemapDir & remap )

virtual

This method is used by 3ds Max to clone an object.

See also: CloneRefHierarchy(), class RemapDir This method is called by 3ds Max to have the plugin clone itself. The plug-in's implementation of this method should copy both the data structure and all the data residing in the data structure of this reference target. The plugin should clone all its references as well. Also, the plug-in's implementation of this method must call BaseClone(). In order for classes derived from this class to clone cleanly, the Clone method should just create the new instance, and then call an implementation of BaseClone that clones the references and copies any other necessary data. For example:
class MyDerivedPlugin

: public MyBasePlugin

{

const int MY_REFERENCE = 1;

ReferenceTarget* Clone(RemapDir& remap)

{

ReferenceTarget* result = new MyDerivedPlugin();

BaseClone(this, result, remap);

return result;

}

void BaseClone(ReferenceTarget* from, ReferenceTarget* to, RemapDir& remap)

{

if (!to || !from || from == to)

return;

MyBasePlugin::BaseClone(from, to, remap);

to->ReplaceReference(MY_REFERENCE, remap->CloneRef(from->GetReference(MY_REFERENCE)));

}

};

ReferenceMaker::GetReference
virtual CoreExport RefTargetHandle GetReference(int i)
Returns the 'i-th' reference.

ReferenceMaker::ReplaceReference
CoreExport RefResult ReplaceReference(int which, RefTargetHandle newtarg, BOOL delOld=TRUE)
Used when cloning reference makers.

ReferenceTarget
A scene entity that is being owned and listened to by other scene entities.
Definition: ref.h:1849

RemapDir
For remapping references during a Clone.
Definition: ref.h:830

RemapDir::CloneRef
virtual RefTargetHandle CloneRef(RefTargetHandle oldTarg)
Creates a clone of a reference target only if it hasn't been cloned already.

This method should not be directly called by plug-ins. Instead, either RemapDir::CloneRef() or CloneRefHierachy() should be used to perform cloning. These methods ensure that the mapping from the original object to the clone is added to the RemapDir used for cloning, which may be used during backpatch operations

Note: See the remarks in method BaseClone() below.

Parameters

remap - A RemapDir instance used for remapping references during a Clone.

Returns: A pointer to the cloned item.

◆ BaseClone()

virtual CoreExport void BaseClone	(	ReferenceTarget *	from,
		ReferenceTarget *	to,
		RemapDir &	remap
	)

virtual

This method copies base class data from an object to its clone.

This method is available in release 4.0 and later only. Virtual method.

Note: All plugins that implement a Clone() method have to call this BaseClone() method from that Clone() method with the old and the new object as parameters. The ordering in regards to when this method is called is unimportant, however this method must, of course, be called after the cloned object is created. This method allows base classes to copy their data into a new object created by the clone operation. As described in the Clone method, the Clone method should just create a new instance and then call the BaseClone method. The BaseClone method should then clones any references and sets any other necessary data. This allows classes that derive from this class to clone cleanly. See the Clone method documentation for a code example. All overrides of BaseClone() must call the base class implementation. The base class implementation copies the CustAttrib objects into the newly created object.

Parameters

from	- Points to the old object to clone.
to	- Points to the new object created.
remap	- This class is used for remapping references during a Clone.

Reimplemented in Control, and MtlBase.

◆ NotifyDependents()

CoreExport RefResult NotifyDependents	(	const Interval &	changeInt,
		PartID	partID,
		RefMessage	message,
		SClass_ID	sclass = `NOTIFY_ALL`,
		BOOL	propagate = `TRUE`,
		RefTargetHandle	hTarg = `nullptr`,
		NotifyDependentsOption	notifyDependentsOption = `REFNOTIFY_ALLOW_OPTIMIZATIONS`
	)

overridevirtual

Notify all dependent RefMakers concerned with the message.

Implemented by the System. This method broadcasts the message specified by the message parameter to all the items which reference this item. Note the following on how reference messages propagate (that is, travel to the dependents):

When a plugin sends a message via NotifyDependents(), the message
1. Propagates to ALL the items that reference it.
2. And also to all the items which reference those items.
3. And so on.
The only exceptions to this are as follows:

The propagate parameter passed is FALSE. In that case the message only goes to the immediate dependents.
If the SClass_ID sclass = NOTIFY_ALL parameter limits the dependents to a certain specified Super Class.
If one of the items that references the plugin, processes the message inside its NotifyRefChanged() and returns REF_STOP instead of REF_SUCCEED. In this case, the message is not further propagated.

Also, whenever a message propagates, the hTarget parameter received in NotifyRefChanged() is reset to the this pointer of the immediate dependent (not the originator) who propagates the message.

Parameters

changeInt	- Currently all plug-ins must pass FOREVER for this interval. This indicates the interval of time over which the change reported by the message is in effect. The exception is the REFMSG_FLAGDEPENDENTS notification. In that case, changeInt.Start() is the timepoint to perform the dependency test.
partID	- This parameter is used to pass message specific information to the items which will receive the message. See the ReferenceMaker::NotifiyRefChanged() method for more details.
message	- The message to broadcast to all dependents. See the ReferenceMaker::NotifiyRefChanged() method for more details.
sclass	- This parameter defaults to NOTIFY_ALL. If this value is passed to NotifyDependents() all dependents will be notified. Other super class values may be passed to only send the message to certain items whose SuperClassID matches the one passed.
propagate	- This parameter defaults to TRUE. This indicates that the message should be sent to all 'nested' dependencies. If passed as FALSE, this parameter indicates the message should only be sent to first level dependents. Normally this should be left to default to TRUE.
hTarg	- This parameter must always default to NULL.
notifyDependentsOption	- This parameter specifies whether duplicate messages to the same refmaker can potentially be optimized away

Returns: This method always returns REF_SUCCEED.

Reimplemented from ReferenceMaker.

◆ FlagDependents()

void FlagDependents	(	TimeValue	t,
		PartID	which = `PART_PUT_IN_FG`
	)

inline

This sends the REFMSG_FLAGDEPENDENTS message up the pipeline.

This sends the REFMSG_FLAGDEPENDENTS message up the pipeline. There are two reasons to flag dependents:

To put the node in the FG plane. (PART_PUT_IN_FG)
To set the node's mesh color to green to indicate it is a dependent. (PART_SHOW_DEPENDENCIES). If the PART_SHOWDEP_ON bit is set, the dependency display is turned on, otherwise it is turned off.
Parameters

t - the timepoint to perform the dependency test.

which - The part id that is sent with REFMSG_FLAGDEPENDENTS

                                                                        { 
            NotifyDependents( Interval(t,t), which, REFMSG_FLAGDEPENDENTS );
        }

◆ NotifyForeground()

virtual void NotifyForeground ( TimeValue t )

inlinevirtual

This method is called to flag dependents into the FG.

This method is called to flag dependents into the FG. (Note that the above method is obsolete) The default implementation just sends out the notification REFMSG_FLAGDEPENDENTS with PART_PUT_IN_FG as the partID. In particular, a driven controller could override this method and call its driver's version of this method

                                                   {
            NotifyDependents(Interval(t,t),PART_PUT_IN_FG,REFMSG_FLAGDEPENDENTS);
        }

◆ NotifyTarget()

virtual void NotifyTarget	(	int	message,
		ReferenceMaker *	hMaker
	)

inlinevirtual

Sends messages to ReferenceTargets.

This method is available in release 4.0 and later only. Used by a ReferenceMaker to send 'reverse' notification messages to its ReferenceTargets, or to this ReferenceTarget.

Parameters

message	- The message sent to the reference target.
hMaker	- The ReferenceMaker sending the message.

Reimplemented in PFSimpleAction.

◆ DoEnumDependentsImpl()

CoreExport int DoEnumDependentsImpl ( DependentEnumProc * dep )

overrideprotectedvirtual

Method to perform an enumeration on a ReferenceTarget.

Implemented by the System. This method is initially called by DoEnumDependents. This method allows a ReferenceTarget to call the given callback object's proc on itself, and then optionally enumerate all references to it. How to continue enumeration is based on the return value from the callback object's proc. All ReferenceTargets have a list of back pointers to entities that directly reference it. The default implementation of this method first checks to see if this ReferenceTarget was previously processed as part of the enumeration, and if so immediately returns 0. If the ReferenceTarget was not previously processed, it calls the callback object's proc on itself and then, dependent on the return value from the callback object's proc, enumerates those back pointers calling DoEnumDependentsImpl once per dependent. Normally you will not need to override this method. If you do override this method, you should use DependentEnumProc::CheckIfAndSetAsVisited to process your instance and its dependents only if it was not previously processed.

Parameters

dep	- The callback object called for each dependent.

Returns: Return 1 to stop the enumeration and 0 to continue.

See also: DependentEnumProc::CheckIfAndSetAsVisited(ReferenceMaker *rmaker)
int RefTargMonitorRefMaker::DoEnumDependentsImpl(DependentEnumProc* dep) {

// If already processed this reftarg once, no need to process it or its dependents again

if (dep->CheckIfAndSetAsVisited(this))

return 0;

int res = dep->proc(this);

if (res == DEP_ENUM_SKIP)

return 0;

else if (res)

return 1;

return mOwner.ProcessEnumDependents(dep);
