globalmapper.InitLidarQueryFilter
=================================

.. currentmodule:: globalmapper
.. py:function:: InitLidarQueryFilter (bool aEmptyClassFilter) -> GM_Error_t32, GM_LidarQueryFilter_t

    Initializes a Lidar query filter. Call this before specifying your own query members.

    A value of False on *aEmptyClassFilter* indicates that all classes will be enabled by default. A value of True
    indicates that all classes will be disabled by default. Update the member mClassFilter[aFilterClass] after
    initialization to set enable(1)/disable(0) status manually.

    :param bool aEmptyClassFilter: Should the class filter have all types disabled to start?
    :returns: Error Code
    :rtype: GM_Error_t32
    :return: The resulting lidar query filter
    :rtype: GM_LidarQueryFilter_t
