How to load a raster dataset to a raster attribute column in a feature class

static void loadToRasterAttribute(IFeatureClass featureClass, IRasterDataset
    rasterDataset, int OID)throws Exception{
    /*Parameters:
    featureClass: the feature class with raster attribute
    rasterDataset: the raster dataset to be loaded to the raster attribute
    OID: the objectid of the feature to be edited
     */

    //Get workspace for editing
    IDataset dataset = (IDataset)featureClass;
    IWorkspaceEdit workspaceEdit = (IWorkspaceEdit)dataset.getWorkspace();
    workspaceEdit.startEditing(false);
    workspaceEdit.startEditOperation();
    IFeature feature = featureClass.getFeature(OID);

    //Find raster field index
    int iRasterField = 0;
    for (int i = 0; i < feature.getFields().getFieldCount(); i++){
        if (feature.getFields().getField(i).getType() ==
            esriFieldType.esriFieldTypeRaster){
            iRasterField = i;
            i = 1000;
        }
    }

    //Create raster value with input raster dataset
    IRasterValue rasterValue = new RasterValue();
    rasterValue.setRasterDatasetByRef(rasterDataset);

    //Set raster value to the raster field
    feature.setValue(iRasterField, rasterValue);
    feature.store();

    //Stop editing and save edits
    workspaceEdit.stopEditOperation();
    workspaceEdit.stopEditing(true);
