Detailed Description

Object to be instantiated on stack that, when destroyed, will disable the custom handler so that it does not call the GScipMessageHandler.

It is used so that the GScipMessageHandler is not called after GScip::Solve() have returned, even if the handler has not been uninstalled and freed properly (when an error occurs).

Constructor & Destructor Documentation

ScopedSCIPMessageHandlerDisabler()

operations_research::internal::ScopedSCIPMessageHandlerDisabler::ScopedSCIPMessageHandlerDisabler ( const MessageHandlerPtr & handler )

explicit

The input handler must be the result of MakeSCIPMessageHandler(). If nullptr (initially or after being reset to null), nothing will happen.

A reference is kept to the input so the caller must make sure this input MessageHandlerPtr will outlive this object.

Note

SCIPmessagehdlrGetData is a macro in optimized builds and a function in debug ones. Hence here we assign the result to a variable instead of chaining the calls.
