Class Description

Class FPInterface, Class FPInterfaceDesc, Function publishing.

Description:

A "Mixin" interface provides a way for a plug-in to expose some of its functionality for use by other plug-ins or MAXScript. The notion of "Mixin" refers to the idea that the interface is a sub-class of the plug-in class and thus "mixed in" with it. Many classes in the SDK now inherit from FPMixinInterface in order to expose some of their functionality.

Developers should see the documentation for Class FPInterface for reference on this class as well.

For an overview of the function publishing system as a whole, see Function publishing.

Member Function Documentation

FPMixinInterface& operator= ( const FPMixinInterface &  rhs )

inlineprotected

{ UNUSED_PARAM(rhs); return *this;}

virtual LifetimeType LifetimeControl ( )

inlinevirtual

Remarks

This method allows inquiries into the actual lifetime policy of a client and provide a server-controlled delete notify callback.

Returns

One of the following LifetimeTypes:

noRelease

Do not call release, use interface as long as you like.

immediateRelease

The interface is only good for one calls. The release is implied so a call to release is not required.

wantsRelease

The clients are controlling the lifetime, so the interface needs a Release() when the client has finished. This is the default.

serverControlled

The server controls the lifetime and will use the InterfaceNotifyCallback to inform the code when it is gone.

Default Implementation:

{ return noRelease; }

Reimplemented from BaseInterface.

Reimplemented in NodeAndAnims, XMLAnimTreeEntryList, GizmoShape, XMLAnimTreeEntry, AssetUser, and Plane.

{ return serverControlled; }

virtual CoreExport bool RegisterNotifyCallback ( InterfaceNotifyCallback *  incb )

virtual

Remarks

This method allows you to register an interface notify callback.

Parameters:

InterfaceNotifyCallback* incb

A pointer to the interface notify callback.

Default Implementation:

{ return false; }

Reimplemented from BaseInterface.

virtual void UnRegisterNotifyCallback ( InterfaceNotifyCallback *  incb )

inlinevirtual

Remarks

This method allows you to un-register an interface notify callback.

Parameters:

InterfaceNotifyCallback incb

A pointer to the interface notify callback.

Default Implementation:

{ }

Reimplemented from BaseInterface.

    { 
        if (interfaceNotifyCBs)
            for (int i=0; i < interfaceNotifyCBs->Count(); i++)
            {
                if (incb == (*interfaceNotifyCBs)[i])
                    interfaceNotifyCBs->Delete(i,1);
            }
    }

virtual BaseInterface* GetInterface ( Interface_ID  id )

inlinevirtual

Remarks

Returns a pointer to the interface whose ID is specified.

Parameters:

Interface_ID id

The ID of the interface to return.

Default Implementation:

{ return NULL; }

Reimplemented from FPInterface.

Reimplemented in INode, SimpleManipulator, ITreeView, ITrackBar, ActionTable, ActionItem, AssetUser, PFSimpleTest, PFSimpleAction, PFSimpleOperator, and PFSimpleActionState.

{ if (id == FPMIXININTERFACE_ID) return this; else return FPInterface::GetInterface(id); }

virtual FPInterfaceDesc* GetDescByID ( Interface_ID  id )

inlinevirtual

Remarks

This method is used to directly implement FPInterface::GetDesc() in your public virtual base mixin class, like this;

FPInterfaceDesc* GetDesc() { return GetDescByID(THIS_INTERFACE_ID); }

Then implement a GetDescByID() in the implementing class to avoid link export issues.

Parameters:

Interface_ID id

The unique interface ID by which to get the FPInterfaceDesc.

Default Implementation:

{ return &nullInterface; }

Reimplemented in ActionTable, ActionItem, and AssetUser.

{ UNUSED_PARAM(id); return &nullInterface; }

virtual Interface_ID GetID ( )

inlinevirtual

Remarks

This method overrides GetID() in those interfaces that do not publish metadata but instead have a unique Interface_ID for quick internal identification in implementation code that might be shared by a bunch of mixin interfaces.

Returns

The Interface_ID.

Default Implementation:

{ return GetDesc()->ID; }

Reimplemented from BaseInterface.

Reimplemented in ILookatControl_Extension, ActionTable, ITreeViewOps, ActionItem, IPopulateFlow, IObjXRefRecord, IXRefObject8, IDaylightSystem2, IXRefItem, ITreeViewUI, AssetUser, IXRefMaterial18, IXRefProxy, INodeTransformMonitor, IXRefAtmospheric, IXRefCtrl, IXRefMaterial, IRefTargMonitorClass, and INodeMonitor.

{ return GetDesc()->ID; }
