1.1.1.5  OcaGain
================

Class Hierarchy:

:ref:`OcaRoot <ocaroot>` : :ref:`OcaWorker <ocaworker>` : :ref:`OcaActuator <ocaactuator>` : :ref:`OcaGain <ocagain>`

.. cpp:class:: OcaGain: OcaActuator

    Gain (or attenuation) element.

    **Properties**:


    .. _ocagain_classid:

    .. cpp:member:: static const OcaClassID ClassID = "1.1.1.5"

        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``.

    .. _ocagain_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``.

    .. _ocagain_gain:

    .. cpp:member:: OcaDB Gain

        Gain in dB.

        This property has id ``4.1``.
