Mergeable Class Reference

#include <Mergeable.h>

Class Description

Description: This class allows referenceTargets that are not INodes to be mergeable through the File->Merge command.

The referenceTarget that you want to be mergeable must derive from Mergeable. You just then need to override GetMergeableRef, GetMergeableRefName, and PostMerge.

Code Example to make the Brightness/Contrast effect mergeable.

You would derive your class from the Mergeable

class BriteConEffect: public Effect, public Mergeable {

Then make sure you return the Mergeable Interface from GetInterface when it is asked

void* BriteConEffect::GetInterface(ULONG id)
{
    switch(id)
    {
        case MERGEABLE_INTERFACE : return (Mergeable *) this;
            break;
        default: return Effect::GetInterface(id);
            break;
    }
}

Next just need to implement GetMergeableRef and GetMergeableRefName which return the data needed to do the merge

ReferenceTarget* BriteConEffect::GetMergeableRef()
{
    return this;
}
MSTR BriteConEffect::GetMergeableRefName()
{
    return GetName();
}

Finally you just need to implement PostMerge where you do your work to hook back up your reference after the merge

void BriteConEffect::PostMerge()
{
    GetCOREInterface()->AddEffect(this);
}

Member Function Documentation

virtual CoreExport ReferenceTarget* GetMergeableRef ( )

pure virtual

This needs to be implemented to return the ReferenceTarget that will be mergeable.

This is the ReferenceTarget that is derived from Mergeable. If it does not derive from Mergeable, PostMerge will not be called on it after merging.

virtual CoreExport MSTR GetMergeableRefName ( )

pure virtual

This returns the name that you want to appear in the merge list box.

virtual CoreExport void PostMerge ( )

pure virtual

This is called after the reference has been merged.

At this point it needs to be attached to something otherwise it will be lost. For instance if this was an effect it would have to be attached to scene graphs effects list.

virtual CoreExport bool SaveForMerge ( )

inlinevirtual

This is called before saving.

If you are in a state where you don't need to be saved, then return false. Otherwise by default this returns true.

{return true;}

virtual CoreExport bool MakeMergeNameUnique ( )

inlinevirtual

The name returned from GetMergeableRefName() will be made unique in the merge list box, unless this is implemented to return false.

{return true;}
