Function Documentation

CallBack()

template<typename Fun >

void CallBack ( const CodeContext::Pointer &  callbackContext, Fun &&  callback  )

inline

Executes service callback in callbackContext. If an exception occurs, the callback context is preserved, so that the exception is associated with the callback that triggered them (rather than with the service).

Service code running in its own service context should use this function.

CallContextCreator()

template<typename Fun >

void CallContextCreator ( Fun &&  creator )

inline

Executes context creator in the service context. If an exception occurs, the creator context is preserved, so that the exception is associated with the creator that triggered them (rather than with the service).

Service code running in its own context should use this function to create new code contexts. TODO: Use or, if this pattern is not repeated, remove.

CallService()

template<typename Fun >

void CallService ( const CodeContext::Pointer &  serviceContext, Fun &&  service  )

inline

Executes service in serviceContext but due to automatic caller context restoration, service exceptions are associated with the caller that suffered from (and/or caused) them (rather than with the service itself).

Service code running in caller's context should use this function to escape into service context (e.g., for submitting caller-agnostic requests).
