Provides infrastructure for the registration of I/O callback functions.
The purpose of DataIOBase
is to provide methods for the registration of I/O callback functions to subclasses implementing the input and output of data objects (see Base::DataReader and Base::DataWriter). I/O callbacks allow client code to be notified whenever a data object was read, written or skipped. I/O callbacks are registered by calling the method registerIOCallback() with an argument of type DataIOBase::IOCallbackFunction. DataIOBase::IOCallbackFunction is a generic functor implementation that is able to wrap any compatible (in terms of return and argument type) function pointer or function object. Therefore, no special requirements beside return and argument types are imposed on the type of the used I/O callback target function.
typedef std::function<void(const DataIOBase&, double)> CDPL::Base::DataIOBase::IOCallbackFunction |
A functor class used to wrap I/O callback target functions.
IOCallbackFunction
allows to wrap any function pointer or function object compatible with a return type of void
and two arguments of type const DataIOBase&
and double
(see [FUNWRP]).
