1.1.2.1.14  OcaJsonSensor
=========================

Class Hierarchy:

:ref:`OcaRoot <ocaroot>` : :ref:`OcaWorker <ocaworker>` : :ref:`OcaSensor <ocasensor>` : :ref:`OcaBasicSensor <ocabasicsensor>` : :ref:`OcaJsonSensor <ocajsonsensor>`

.. cpp:class:: OcaJsonSensor: OcaBasicSensor

    JSON value actuator, with or without schema.

    **Properties**:


    .. _ocajsonsensor_classid:

    .. cpp:member:: static const OcaClassID ClassID = "1.1.2.1.14"

        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``.

    .. _ocajsonsensor_classversion:

    .. cpp:member:: static const OcaClassVersionNumber ClassVersion = 1

        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``.

    .. _ocajsonsensor_maxlen:

    .. cpp:member:: OcaUint16 MaxLen

        Maximum length of the returned value. May be readonly in some
        implementations.

        This property has id ``5.2``.

    .. _ocajsonsensor_value:

    .. cpp:member:: OcaJsonValue Value

        The JSON value.

        This property has id ``5.1``.
