CustomOperation

class hoomd.custom.CustomOperation(trigger, action)

Bases: TriggeredOperation

User defined operation.

This is the parent class for hoomd.tune.CustomTuner, hoomd.update.CustomUpdater. and hoomd.write.CustomWriter. These classes wrap Python objects that inherit from hoomd.custom.Action so they can be added to the simulation operations.

This class also implements a “pass-through” system for attributes. Attributes and methods from the passed in action will be available directly in this class. This does not apply to attributes with these names: trigger, _action, and action.

Note

Due to the pass through no attribute should exist both in hoomd.custom.CustomOperation and the hoomd.custom.Action.

Note

This object should not be instantiated or subclassed by an user.
