Registry for various processing components, including providers, algorithms
|
|
and various parameters and outputs.

QgsProcessingRegistry is not usually directly created, but rather accessed through
|
|
:py:func:`QgsApplication.processingRegistry()`

Constructor for QgsProcessingRegistry.

Get list of available providers.

bool addProvider( QgsProcessingProvider *provider /Transfer/ );
|
|
%Docstring
|
|
Add a processing provider to the registry. Ownership of the provider is transferred to the registry,
|
|
and the provider's parent will be set to the registry.
|
|
Returns false if the provider could not be added (eg if a provider with a duplicate ID already exists
|
|
in the registry).
|
|
Adding a provider to the registry automatically triggers the providers :py:func:`QgsProcessingProvider.load()`
|
|
method to populate the provider with algorithms.

%End

bool removeProvider( QgsProcessingProvider *provider );
|
|
%Docstring
|
|
Removes a provider implementation from the registry (the provider object is deleted).
|
|
Returns false if the provider could not be removed (eg provider does not exist in the registry).
|
|
|
|
.. seealso:: :py:func:`addProvider`

const QgsProcessingAlgorithm *algorithmById( const QString &id ) const;
|

%Docstring
|
|
Finds an algorithm by its ID. If no matching algorithm is found, a None
|
|
is returned.
|
|
|
|
.. seealso:: :py:func:`algorithms`
|
|
|
|

|
|

|
QgsProcessingAlgorithm *createAlgorithmById( const QString &id, const QVariantMap &configuration = QVariantMap() ) const /TransferBack/;
|
|
%Docstring
|
|
Creates a new instance of an algorithm by its ID. If no matching algorithm is found, a None
|
|
is returned. Callers take responsibility for deleting the returned object.
|
|
|
|
The ``configuration`` argument allows passing of a map of configuration settings
|
|
to the algorithm, allowing it to dynamically adjust its initialized parameters
|
|
and outputs according to this configuration. This is generally used only for
|
|
algorithms in a model, allowing them to adjust their behavior at run time
|
|
according to some user configuration.
