class ParentSetCollector
Defined at line 23 of file ../../src/devices/bin/driver_manager/composite/parent_set_collector.h
|ParentSetCollector| wraps functionality for collecting multiple parent nodes for composites.
The parent set starts out empty and gets nodes added to it until it is complete. Once complete
it will return a vector containing all the parent node pointers.
Public Methods
zx::result<> AddNode (uint32_t index, const std::vector<fuchsia_driver_framework::NodeProperty2> & node_properties, std::weak_ptr<Node> node)Add a node to the parent set at the specified index.
Caller should check that |ContainsNode| is false for the index before calling this.
Only a weak_ptr of the node is stored by this class (until collection in GetIfComplete).

zx::result<std::shared_ptr<Node>> TryToAssemble (std::string_view name, NodeManager * node_manager, async_dispatcher_t * dispatcher)Check if all parents are found. If so, then create and return the composite node. If the
node is already created, return ZX_ERR_ALREADY_EXISTS.
