Class DistributedAppService

• Defined in File fragment_service.hpp

Base Types

• public holoscan::FragmentService (Class FragmentService)

• public holoscan::distributed::ServiceDriverEndpoint (Class ServiceDriverEndpoint)

• public holoscan::distributed::ServiceWorkerEndpoint (Class ServiceWorkerEndpoint)

Derived Type

• public holoscan::PoseTreeManager (Class PoseTreeManager)

class DistributedAppService : public holoscan::FragmentService, public holoscan::distributed::ServiceDriverEndpoint, public holoscan::distributed::ServiceWorkerEndpoint

Composite service interface for distributed fragment services.

DistributedAppService combines the FragmentService interface with distributed endpoint capabilities, allowing a single service implementation to:

• Manage shared resources within a fragment (FragmentService)

• Act as a driver coordinator in distributed applications (ServiceDriverEndpoint)

• Act as a worker participant in distributed applications (ServiceWorkerEndpoint)

This composite interface is particularly useful for services that need to synchronize state or coordinate operations across multiple fragments in a distributed Holoscan application. When registered with the application using register_service(), the framework automatically calls the appropriate driver/worker methods based on each fragment’s role.

Note

In single-fragment applications, only the FragmentService interface is used. The distributed endpoint methods are only called in multi-fragment distributed applications.

Public Functions

FragmentService() = default

Inherit constructors from base classes.

This using declaration enables construction of DistributedAppService using the constructors of FragmentService, ServiceDriverEndpoint, and ServiceWorkerEndpoint, providing flexibility in how derived classes can be initialized.
