class RuntimeContextStorage

RuntimeContextStorage is used by RuntimeContext to store Context frames.

Custom context management strategies can be implemented by deriving from this class and passing an initialized RuntimeContextStorage object to RuntimeContext::SetRuntimeContextStorage.

Subclassed by opentelemetry::context::ThreadLocalContextStorage

Public Functions

virtual Context GetCurrent() noexcept = 0

Return the current context.

Returns:: the current context

virtual nostd::unique_ptr<Token> Attach(const Context &context) noexcept = 0

Set the current context.

Parameters:: the – new current context
Returns:: a token for the new current context. This never returns a nullptr.

virtual bool Detach(Token &token) noexcept = 0

Detach the context related to the given token.

Parameters:: token – a token related to a context
Returns:: true if the context could be detached
