1.1.7  OcaDatasetWorker
=======================

Class Hierarchy:

:ref:`OcaRoot <ocaroot>` : :ref:`OcaWorker <ocaworker>` : :ref:`OcaDatasetWorker <ocadatasetworker>`

.. cpp:class:: OcaDatasetWorker: OcaWorker

    Abstract base class for Dataset Workers, i.e. Workers that perform
    operations on Datasets.

    **Properties**:


    .. _ocadatasetworker_classid:

    .. cpp:member:: static const OcaClassID ClassID = "1.1.7"

        Number that uniquely identifies the class. Note that this differs from
        the object number, which identifies the instantiated object. This
        property is an override of the **OcaRoot** property.

        This property has id ``1.1``.

    .. _ocadatasetworker_classversion:

    .. cpp:member:: static const OcaClassVersionNumber ClassVersion = 3

        Identifies the interface version of the class. Any change to the class
        definition leads to a higher class version. This property is an override
        of the **OcaRoot** property.

        This property has id ``1.2``.

    .. _ocadatasetworker_datasetono:

    .. cpp:member:: OcaONo DatasetONo

        ONo of the **OcaDataset** object that this Dataset Worker is currently
        working on, zero if none.

        This property has id ``3.1``.

    **Methods**:


    .. _ocadatasetworker_getdatasetono:

    .. cpp:function:: OcaStatus GetDatasetONo(OcaONo &ONo)

        Returns object number associated Dataset Object, or zero if no Dataset
        is associated. Note: There is no corresponding **Set(...)** method,
        because it is assumed the Dataset will be associated either at
        construction time, or by actions defined by child classes, e.g. the
        **Open(...)** method of the child class **OcaMediaRecorderPlayer**.

        This method has id ``3.1``.

        - :cpp:expr:`ONo`: Output parameter.
