Enumeration Type Documentation

◆ RefResult

enum RefResult

Return codes for reference handling and message processing methods.

Enumerator
REF_FAIL	The operation failed.
REF_HALT	Return this from your implementation of ReferenceMaker::NotifyRefChanged() in order to immediately stop sending the reference message to dependents of the RefereneTarget the message originates from.
REF_SUCCEED	The operation succeeded.
REF_DONTCARE	The results of the operation don't matter.
REF_STOP	Return this from your implementation of ReferenceMaker::NotifyRefChanged() to stop propagating the reference message to your dependents, but allow it to be sent to the other dependents of the ReferenceTarget the message originates from.
REF_INVALID	Attempts to delete an invalid reference will return this value.
REF_AUTO_DELETE	Return this from your implementation of ReferenceMaker::NotifyRefChanged() in response to a REFMGS_TAGET_DELETED message to indicate that all the reference targets you depended on have been deleted, and you also wish to be deleted from the scene.

                {
     REF_FAIL = 0,
     REF_HALT = 0,
     REF_SUCCEED,
     REF_DONTCARE,
     REF_STOP,
     REF_INVALID,

◆ NotifyDependentsOption

enum NotifyDependentsOption

Specified as argument to NotifyDependents to specify level of optimizations used.

Enumerator
REFNOTIFY_ALLOW_OPTIMIZATIONS	Duplicate messages (same hTarg, message, and partID) to same refmaker are blocked. Not all message types are blocked, some are always allowed as duplicates to allow proper operation of 3dsmax Note that this option can be turned off entirely by the user in the .ini by setting EnableOptimizeDependentNotifications=0
REFNOTIFY_DISALLOW_OPTIMIZATIONS	Duplicate messages are not blocked.
REFNOTIFY_INTERNAL_PROPAGATION_ALLOW_OPTIMIZATIONS	Used internally when propagating notifications.
REFNOTIFY_INTERNAL_PROPAGATION_ALLOW_OPTIMIZATIONS_ENABLED
REFNOTIFY_INTERNAL_PROPAGATION_DISALLOW_OPTIMIZATIONS

                             {
     REFNOTIFY_ALLOW_OPTIMIZATIONS = 0,
     REFNOTIFY_DISALLOW_OPTIMIZATIONS,
     //
     // Optimizations permitted but not active; typically message is not optimizable (but may be
     // changed to an optimizable message further down the dependency chain)
     REFNOTIFY_INTERNAL_PROPAGATION_ALLOW_OPTIMIZATIONS,
     // Optimizations permitted and currently active
     REFNOTIFY_INTERNAL_PROPAGATION_ALLOW_OPTIMIZATIONS_ENABLED,

Function Documentation

◆ CanOptimizeDependentNotifications()

CoreExport bool CanOptimizeDependentNotifications	(	NotifyDependentsOption	notifyDependentsOption,
		RefMessage	message,
		NotifyDependentsOption &	propagated_notifyDependentsOption
	)

Returns true if this RefMessage can have redundant notifications optimized (inhibited).

Parameters

notifyDependentsOption	- Specifies the level of optimization currently in use.
message	- Type of notification message that may be sent.
propagated_notifyDependentsOption	- Returns the level of optimization dependents should request.

Returns: true if the message can be optimized; false if it cannot.

◆ NewRemapDir()

CoreExport RemapDir* NewRemapDir ( BOOL use_A_WORK2_flag = FALSE )

Gets a pointer to a default version of a RemapDir.

See also: CloneRefHierarchy(), ReferenceTarget::Clone() You must delete the RemapDir returned by this function when done using it via the DeleteThis method. When the boolean use_A_WORK2_flag is set to TRUE, the remap directory will set this flag on all entries in the remap directory, and will assume that any object that DOESN'T have this flag set is not in the remap directory. This avoids the search through the directory and speeds up things greatly. When using this feature, you must first clear A_WORK2 on all of the objects being cloned. DS: 3/17/00. When the instance is deleted, the Backpatch() method is automatically called if backpatch operations were added but never performed.

Precondition: First clear the A_WORK2 flag on all objects being cloned.

Postcondition: Flag is set on all entries in remap directory.

Parameters

use_A_WORK2_flag - used to set this flag on all entries in the remap directory.

◆ CloneRefHierarchy()

CoreExport ReferenceTarget* CloneRefHierarchy ( ReferenceTarget * rm )

This function is used to clone a single ReferenceTarget.

See also: Class RemapDir, ReferenceTarget::Clone() Implemented by system. This function should be used by plug-ins to clone a single ReferenceTarget instead of ReferenceTarget::Clone(RemapDir*) Calling ReferenceTarget::Clone() does not add the old/new ReferenceTargets to the RemapDir passed to Clone, and any backpointers in the reference hierarchy under the original ReferenceTarget that points back to that ReferenceTarget will fail to backpatch correctly. This function takes care of setting up the RemapDir, calling Clone, adding the old/new ReferenceTargets to the RemapDir, and having the RemapDir perform backpatching. So instead of:

ReplaceReference(IPBLOCK,ipblock->Clone(DefaultRemapDir()));

DefaultRemapDir

Implements a default version of a RemapDir.

Definition: ref.h:1082

IPBLOCK

#define IPBLOCK

Interpolations parameter block.

Definition: object.h:4350

you should say:

ReplaceReference(IPBLOCK,CloneRefHierarchy(ipblock));

CloneRefHierarchy

CoreExport ReferenceTarget * CloneRefHierarchy(ReferenceTarget *rm)

This function is used to clone a single ReferenceTarget.

If you are cloning multiple ReferenceTargets, you should be creating a RemapDir and cloning the ReferenceTargets using RemapDir::CloneRef. Otherwise, any common ReferenceTarget under the ReferenceTargets being cloned would be cloned as separate ReferenceTargets, rather than a single ReferenceTarget that is shared. So, for example:

RemapDir *remap = NewRemapDir();
ReplaceReference(DRIVER_CONTROL_REF, remap->CloneRef(from.driverCont));
ReplaceReference(DRIVEN_CONTROL_REF, remap->CloneRef(from.drivenCont));
remap->Backpatch();
remap->DeleteThis();

Parameters

rm	- A pointer to the reference target to clone.

Returns: A pointer to the new reference target

◆ RegisterGlobalReference()

CoreExport void RegisterGlobalReference ( GlobalReferenceMaker * maker )

Registers an instance of this class whose NotifyRefChanged() method will receive the messages.

Parameters

maker - Points to an instance of this class whose NotifyRefChanged() method will receive the messages

◆ UnRegisterGlobalReference()

CoreExport void UnRegisterGlobalReference ( GlobalReferenceMaker * maker )

Unregisters the class so it won't be called anymore.

Parameters

maker - Points to an instance of this class whose NotifyRefChanged() method will no longer receive the messages

◆ ClearAFlagInHierarchy()

CoreExport void ClearAFlagInHierarchy	(	RefMakerHandle	rm,
		DWORD	mask
	)

Clears the specified Animatable Flag bits in a reference hierarchy.

This method calls ClearAFlag on the ReferenceMaker and all references from it, recursively, with the specified mask

Parameters

rm	- The handle to the root ReferenceMaker to enumerate from
mask	The bits to turn off in the Animatable flags

◆ ClearAFlagInAllAnimatables()

CoreExport void ClearAFlagInAllAnimatables ( DWORD mask )

Clears the specified Animatable Flag bits on all Animatables.

This method calls ClearAFlag on all Animatables with the specified mask

Parameters

mask	The bits to turn off in the Animatable flags

◆ DependsOn()

CoreExport BOOL DependsOn	(	RefMakerHandle	mkr,
		RefMakerHandle	targ
	)

Checks if there is a path of references from a ReferenceMaker to a ReferenceTarget.

Parameters

mkr	- The handle to the ReferenceMaker
targ	- The handle to the ReferenceTarget

Returns: TRUE if there is a path of references from the to targ. This returns TRUE if mkr==targ)

◆ GetSavingVersion()

CoreExport DWORD GetSavingVersion ( )

Function to find out if we are saving an old version of a .MAX file.

Returns

If this returns 0, then either we are not in a save or we are saving the current version.
If it returns non-zero, it is the 3ds Max release number being saved, such as MAX_RELEASE_R12, etc This function can be used in NumRefs() and GetRef() to make an objects references appear as they did in the old Max version.

See also: ISave::SavingVersion()

◆ SetSavingVersion()

CoreExport DWORD SetSavingVersion ( DWORD version )

Function used internally to maintain the SavingVersion number, which should not be called by plugins.

◆ DisableRefMsgs()

CoreExport void DisableRefMsgs ( )

Disable reference messages globally.

The references messages are enabled by default.

Important: It is not recommended that 3rd party plugins disable reference messages. For 3ds Max to function correctly, every call to DisableRefMsgs() needs to be matched with a call to EnableRefMsgs().

Note: the following reference messages are not disabled even when reference messages are globally disabled:

REFMSG_GET_PARAM_NAME_LOCALIZED
REFMSG_GET_PARAM_NAME_NONLOCALIZED
REFMSG_TARGET_DELETED

◆ EnableRefMsgs()

CoreExport void EnableRefMsgs ( )

Enable reference messages globally.

The references messages are enabled by default.

Important: For 3ds Max to function correctly, every call to DisableRefMsgs() needs to be matched with a call to EnableRefMsgs(). Occasionally, when a plugin needs to re-enable reference messages while in a context in which they have been disabled (very likely by the plugin itself), it is important that it calls EnableRefMsgs() as many times as DisableRefMsgs() has been called. When the plugin finished its task, it should restore the reference message propagation to the previous state. The correct way to achieve this is as follows:

// Enable reference messages propagation temporarily.
auto disable_ref_msg_count = IsRefMsgsDisabled();
for(auto i = 0; i < disable_ref_msg_count; ++i) 
{
    EnableRefMsgs();
}
...
// Perform work that requires reference message propagation to be enabled
...
// Restore state of reference message propagation
for (auto i = 0; i < disable_ref_msg_count; ++i)
{
    DisableRefMsgs();
}

◆ IsRefMsgsDisabled()

CoreExport DWORD IsRefMsgsDisabled ( )

Returns the number of times reference messages have been marked as disabled. 0 means reference messages are enabled.
