[Qgis-developer] Error in Processing

[Alexander Bruy]

Hi Pedro,

GdalAlgorithm is an internal Processing class and should not
be used in 3rd party plugins.

The error happens because GdalAlgorithm class was refactored
and new mandatory methods were introduced. Personally I think
that all 3rd party plugins should use only public Processing API,
e.g. GeoAlgorithm class.
