1.1.1.3  OcaPolarity
====================

Class Hierarchy:

:ref:`OcaRoot <ocaroot>` : :ref:`OcaWorker <ocaworker>` : :ref:`OcaActuator <ocaactuator>` : :ref:`OcaPolarity <ocapolarity>`

.. cpp:class:: OcaPolarity: OcaActuator

    Signal inverter

    **Properties**:


    .. _ocapolarity_classid:

    .. cpp:member:: static const OcaClassID ClassID = "1.1.1.3"

        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``.

    .. _ocapolarity_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``.

    .. _ocapolarity_state:

    .. cpp:member:: OcaPolarityState State

        Current state of the inverter - {noninverted, inverted].

        This property has id ``4.1``.

    **Methods**:


    .. _ocapolarity_getstate:

    .. cpp:function:: OcaStatus GetState(OcaPolarityState &state)

        Gets the inversion state (i.e. value of the **State** property.

        This method has id ``4.1``.

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


    .. _ocapolarity_setstate:

    .. cpp:function:: OcaStatus SetState(OcaPolarityState state)

        Sets the inversion state (i.e. value of the **State** property).

        This method has id ``4.2``.

        - :cpp:expr:`state`: Input parameter.
