Member Function Documentation

bool QgsVectorLayerRenderer::render ( )

virtual

Do the rendering (based on data stored in the class)

Implements QgsMapLayerRenderer.

void QgsVectorLayerRenderer::setGeometryCachePointer

(

QgsGeometryCache *

cache

)

where to save the cached geometries

Note

The way how geometries are cached is really suboptimal - this method may be removed in future releases
