globalmapper.FlushLayerCache
============================

.. currentmodule:: globalmapper
.. py:function:: FlushLayerCache (GM_LayerHandle_t32 aLayer) -> GM_Error_t32

    Flushes any in-memory cache for the layer. This is mainly useful in low-memory environments like Windows CE and
    typically only does anything for raster formats like GeoTIFF files. Most users will never need to call this.

    :param GM_LayerHandle_t32 aLayer: the layer to flush
    :returns: Error Code
    :rtype: GM_Error_t32
