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

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 QgsProcessingProvider.load()
method to populate the provider with algorithms.
.. seealso:: removeProvider()
:rtype: bool
%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:: addProvider()
:rtype: bool
%End
bool removeProvider( const QString &providerId );

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).

%Docstring
Returns a matching provider by provider ID.

Returns a list of all available algorithms from registered providers.

%Docstring
Finds an algorithm by its ID. If no matching algorithm is found, a None
is returned.

Emitted when a provider has been added to the registry.

Emitted when a provider is removed from the registry
