Detailed Description

A base class for any REST event process.

One of the core classes of REST. Absract class from which all REST "event process classes" must derive. An event process in REST is an atomic operation on one single (input) event, potentially producing a different (output) event. Which type of (input/output) events will depent on the type of process. Processes can be tailored via metadata classes. All this needs to be defined in the inherited class. TRestEventProcess provides the basic structure (virtual functions)

◆ fSingleThreadOnly

bool TRestEventProcess::fSingleThreadOnly = false

protected

It defines if the process can run only under single std::thread mode. If true, the whole process chain will not use multithreading. Useful for processes with viewing functionality. Always true for external processes.

◆ fValidateObservables

bool TRestEventProcess::fValidateObservables = false

protected

It defines if observable names should be added to the validation list.
