Interfacepublic interface CommandLifecycle
Implementors DefaultCommandLifecycle

Represents the lifecycle of a command. This is a hook that can be used by frameworks to add functionality to the command execution. A typical example is integration into an IOC container where the command is supposed to be managed by the container for the time it is getting executed and where the creation of the command instance may also be managed by the container. But this in entirely generic hook that can be used for any kind of additional functionality.
