# User defined execution objects now usable with runtime selection of device adapter
- Changed how Execution objects are created and passed from the cont environment to the execution environment. See chapter 13.9 on worklets in the user manual for details.
- Instead we will now fill out a class and call prepareForExecution() and create the execution object for the execution environment from this function. This way we do not have to template the class that extends `vtkm::cont::ExecutionObjectBase` on the device.
Example of new execution object:
```cpp
template <typename Device>
