Detailed Description

Base interface for all Persistent Configuration Repository adapters.

Member Typedef Documentation

◆ AdapterIdType

using rtctk::componentFramework::PersistentRepoIf::AdapterIdType = elt::mal::Uri

The type used to distinguish between different adapters implementing RuntimeRepoIf.

This is used to specialise the FactoryRegistry to make it suitable for adapter factories discriminated using a URI to select different backend implementations of the repository service.

Member Function Documentation

◆ CreateAdapter()

std::unique_ptr< PersistentRepoIf > rtctk::componentFramework::PersistentRepoIf::CreateAdapter ( const elt::mal::Uri & uri )

static

Factory method used to create the appropriate Persistent Configuration Repository adapter depending on the URI scheme.

The URI schemes supported by the factory method include the following:

cii.config - Will create an instance of PersistentRepoAdapter, which is backed by the CII configuration service.

Parameters

[in] uri The URI of the repository that needs to be accessed.

Returns: A unique pointer to the newly created adapter object. The caller must clean the object up once it is no longer needed.

Exceptions

UnsupportedUriException	If the URI is not supported.
AdapterCreationException	If the factory failed to create a new instance. This will contain nested exceptions caught from the adapter class constructor.

Thread Safety: thread-safe

Exception Safety: basic
