示例1:

HDF5RecordingData::HDF5RecordingData(DataSet* data)
{
    DataSpace dSpace;
    DSetCreatPropList prop;
    ScopedPointer<DataSet> dataSet = data;
    hsize_t dims[3], chunk[3];

    dSpace = dataSet->getSpace();
    prop = dataSet->getCreatePlist();

    dimension = dSpace.getSimpleExtentDims(dims);
    prop.getChunk(dimension,chunk);

    this->size[0] = dims[0];
    if (dimension > 1)
        this->size[1] = dims[1];
    else
        this->size[1] = 1;
    if (dimension > 1)
        this->size[2] = dims[2];
    else
        this->size[2] = 1;

    this->xChunkSize = chunk[0];
    this->xPos = dims[0];
    this->dSet = dataSet;
    this->rowXPos.clear();
    this->rowXPos.insertMultiple(0,0,this->size[1]);
