EventLambda Class Reference

#include <evo/event.h>

Inheritance diagram for EventLambda:

Detailed Description

Implement Event using a lambda function (C++11).

• This basically wraps an Event with a lambda
• This can add overhead if the lambda is over a few lines or has complex state (exact conditions depend on compiler) – for best performance create a type derived from Event directly

Member Function Documentation

operator()()

bool operator() ( )

inlinevirtual

Event function.

• This is called by EventQueue to process the event
• The return value identifies whether the caller should free this object
• Caution: This must not throw any exception

Returns

Whether event is finished and ready to be freed, false if ownership was transferred elsewhere

Implements Event.

operator=()

EventLambda& operator= ( const EventLambda &  src )

inline

Assignment operator.

Parameters

src	Source to copy

Returns

This
