#### 7.3.1 Customizing Reinitialization ¶

Methods for reinitialize-instance may be defined to specify actions to be taken when an instance is updated. If only after methods for reinitialize-instance are defined, they will be run after the system-supplied primary method for initialization and therefore will not interfere with the default behavior of reinitialize-instance.

Methods for shared-initialize may be defined to customize class redefinition. For more information, see Shared-Initialize.
