POP_BlindData proper useage

[Guest xionmark]

And now without the blind data member var in the POP declaration; I think this is the way it's intended to be used. Just have to figure out the duplicate() method.

See attached.

Hi Mike,

Can't seem to get the duplicate() method to get called. I've attached the current code and a hip file that has 3 pop networks. The subsampling, preroll, etc. does what's expected, but I never seem to see the duplicate() method.

Anyway, here's the salient parts of the code that does work well (so far):

class MyBlindData : public POP_BlindData
{
    public:
    int     anInt;
    float   aFloat;
    float   aFloatArray[5];

    MyBlindData(POP_Node *node) : POP_BlindData(node) {
        cout << "MyBlindData constructor called" << endl;
        anInt = 0;
        aFloat = 0.0f;
        aFloatArray[0] = 0.0;
        aFloatArray[1] = 0.0;
        aFloatArray[2] = 0.0;
        aFloatArray[3] = 0.0;
        aFloatArray[4] = 0.0;
    }
    virtual ~MyBlindData() {}

    POP_BlindData *duplicate(const POP_ContextData *src);
    int resetSimulation();
};

int MyBlindData::resetSimulation(){

    cout << "MyBlindData::resetSimulation() called" << endl;
    anInt = 0;
    aFloat = 0.0f;
    aFloatArray[0] = 0.0;
    aFloatArray[1] = 0.0;
    aFloatArray[2] = 0.0;
    aFloatArray[3] = 0.0;
    aFloatArray[4] = 0.0;

 return 0;
}


POP_BlindData * MyBlindData::duplicate(const POP_ContextData *src) {
    cout << "MyBlindData::duplicate() called " << endl;

//     POP_ContextData *_tmpPopContext;
//     _tmpPopContext->copyFrom(*src);

    MyBlindData *myTmpBlindData;
    myTmpBlindData = (MyBlindData*)src->getBlindData(this->getOwner());

    if (!myTmpBlindData)  {
        myTmpBlindData = new MyBlindData(this->getOwner());
        myTmpBlindData->anInt = 200;
        myTmpBlindData->aFloat = 200.23f;
        myTmpBlindData->aFloatArray[0] = 200.1;
        myTmpBlindData->aFloatArray[1] = 200.2;
        myTmpBlindData->aFloatArray[2] = 200.3;
        myTmpBlindData->aFloatArray[3] = 200.4;
        myTmpBlindData->aFloatArray[4] = 200.5;
/*        if(!src->addBlindData((POP_BlindData *)myTmpBlindData))
            cout << "MyBlindData::duplicate() - adding blind data FAILED" << endl;
        else
            cout << "MyBlindData::duplicate() - added blind data " << endl;*/
    }

    return (POP_BlindData *)this;
};

   MyBlindData *myTmpBlindData;
    myTmpBlindData = (MyBlindData*)data->getBlindData(this);

    if (!myTmpBlindData)  {
        myTmpBlindData = new MyBlindData(this);
        myTmpBlindData->anInt = 1;
        myTmpBlindData->aFloat = radius;
        myTmpBlindData->aFloatArray[0] = radius;
        myTmpBlindData->aFloatArray[1] = radius;
        myTmpBlindData->aFloatArray[2] = radius;
        myTmpBlindData->aFloatArray[3] = radius;
        myTmpBlindData->aFloatArray[4] = radius;
        if(!data->addBlindData((POP_BlindData *)myTmpBlindData))
            cout << "Adding blind data FAILED" << endl;
        else
            cout << "Added blind data " << endl;
    }
    else {
        myTmpBlindData->anInt += 1;
        myTmpBlindData->aFloat += radius;
        cout << "Blind data: anInt " << myTmpBlindData->anInt << endl;
        cout << "Blind data: aFloat " << myTmpBlindData->aFloat << endl;
        for(int i =0; i < 5; ++i){
            myTmpBlindData->aFloatArray[i] += radius;
            cout << "Blind data: aFloatArray[" << i << "] = " << myTmpBlindData->aFloatArray[i] << endl;
        }
    }
    cout << endl;
