set_binding_map(mapping)[source]

Configure the binding name mapping for the next driver only.

bind_resource(resource)[source]

Bind the resource to this target.

bind_driver(client)[source]

Bind the driver to all suppliers (resources and other drivers).

Currently, we only support binding all suppliers at once.

bind(bindable)[source]
activate(client, name=None)[source]

Activate the client by activating all bound suppliers. This may require deactivating other clients.

deactivate(client, name=None)[source]

Recursively deactivate the client’s clients and itself.

This is needed to ensure that no client has an inactive supplier.

Returns the list of all objects that were deactivated

deactivate_all_drivers()[source]

Deactivates all drivers in reversed order they were activated

export()[source]

Export information from drivers.

All drivers are deactivated before being exported, unless their skip_deactivate_on_export property is true.

The Strategy can decide for which driver the export method is called and with which name. Otherwise, all drivers are exported.

cleanup()[source]

Clean up connected drivers and resources in reversed order
