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 reference 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.
int CDPL.Base.DataIOBase.registerIOCallback | ( | VoidDataIOBaseFunctor | func | ) |
Registers an I/O callback target function.
func | A DataIOBase.IOCallbackFunction instance wrapping the target function. |
None CDPL.Base.DataIOBase.unregisterIOCallback | ( | int | id | ) |
Unregisters the I/O callback function specified by id.
If a registered callback with the identifier id does not exist, the method has no effect.
id | The identifier of the callback function to unregister. |
None CDPL.Base.DataIOBase.invokeIOCallbacks | ( | float | progress | ) |
Invokes all registered I/O callback functions with the argument self
.
progress | An indicator for the progress of the current I/O operation in the range [0, 1]. |
