hoomd.operation¶

Overview

`Compute`	Base class for all HOOMD computes.
`Operation`	Represents operations that are added to an `hoomd.Operations` object.
`Tuner`	Base class for all HOOMD tuners.
`Updater`	Base class for all HOOMD updaters.
`Writer`	Base class for all HOOMD analyzers.

Details

Base classes for all HOOMD-blue operations.

class hoomd.operation.Operation¶

Represents operations that are added to an hoomd.Operations object.

Operations in the HOOMD-blue data scheme are objects that operate on a hoomd.Simulation object. They broadly consist of 5 subclasses: Updater, Writer, Compute, Tuner, and hoomd.integrate.BaseIntegrator. All HOOMD-blue operations inherit from one of these five base classes. To find the purpose of each class see its documentation.

Note

Developers or those contributing to HOOMD-blue, see our architecture file for information on HOOMD-blue’s architecture decisions regarding operations.

property loggables¶

Name, category mapping of loggable quantities.

Type: dict[str, str]

class hoomd.operation.Compute¶

Base class for all HOOMD computes.

A compute is an operation which computes some property for another operation or use by a user.

Note

This class should not be instantiated by users. The class can be used for isinstance or issubclass checks.

class hoomd.operation.Tuner¶

Base class for all HOOMD tuners.

A tuner is an operation which tunes the parameters of another operation for performance or other reasons. A tuner does not modify the current microstate of the simulation. That is a tuner does not change quantities like temperature, particle position, or the number of bonds in a simulation.

Note

This class should not be instantiated by users. The class can be used for isinstance or issubclass checks.

class hoomd.operation.Updater(trigger)¶

Base class for all HOOMD updaters.

An updater is an operation which modifies a simulation’s state.

Note

This class should not be instantiated by users. The class can be used for isinstance or issubclass checks.

class hoomd.operation.Writer(trigger)¶

Base class for all HOOMD analyzers.

An analyzer is an operation which writes out a simulation’s state.

Note

This class should not be instantiated by users. The class can be used for isinstance or issubclass checks.
