WidgetType
Types of dialogs which Processing widgets can be created for.
Abstract base class for processing algorithms.
Map canvas is a class for displaying all GIS data types on a canvas.

This method needs to be reimplemented in all classes which implement this interface and return an exp...
An interface for objects which can create Processing contexts.
Expression contexts are used to encapsulate the parameters around which a QgsExpression should be eva...
Reads and writes project states.
As part of the API refactoring and improvements which landed in the Processing API was substantially reworked from the x version This was done in order to allow much of the underlying Processing framework to be ported into allowing algorithms to be written in pure substantial changes are required in order to port existing x Processing algorithms for QGIS x The most significant changes are outlined not GeoAlgorithm For algorithms which operate on features one by consider subclassing the QgsProcessingFeatureBasedAlgorithm class This class allows much of the boilerplate code for looping over features from a vector layer to be bypassed and instead requires implementation of a processFeature method Ensure that your algorithm(or algorithm 's parent class) implements the new pure virtual createInstance(self) call
Abstract interface for generating an expression context.

Base class for the definition of processing parameters.
Represents a vector layer which manages a vector based data sets.
Contains information about the context in which a processing algorithm is executed.
Standard algorithm dialog.
