All Methods Instance Methods Abstract Methods Deprecated Methods
Modifier and Type	Method	Description
`void`	`begin(Step step, World world)`	Deprecated. Called before a simulation step is performed.
`void`	`end(Step step, World world)`	Deprecated. Called after a simulation step has been performed.
`void`	`postSolve(Step step, World world)`	Deprecated. Called after the world has been solved but before new contacts are found.
`void`	`updatePerformed(Step step, World world)`	Deprecated. Called after collision detection and contact updates have been performed due to a call to the `World.setUpdateRequired(boolean)` passing true.
