# Canary Lifecycle
|
|
|
|
|
|
|
|
|
|
*You can override several methods to hook into command handler's lifecycle.
|
|
|
|
|
These methods start with `Exec*`*
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
- `ExecOnMessageAsync` runs first right after any message was received
|
|
|
|
|
- `ExecInputTransformAsync` runs after ExecOnMessageAsync and allows you to transform the message content before the bot looks for the matching command
|
|
|
|
|
- `ExecPreCommandAsync` runs after a command was found but not executed, allowing you to potentially prevent command execution
|
|
|
|
|
- `ExecPostCommandAsync` runs if the command was successfully executed
|
|
|
|
|
- `ExecOnNoCommandAsync` runs instead of ExecPostCommandAsync if no command was found for a message
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
*Besides that, canaries have 2 methods with which you can initialize and cleanup your canary*
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
- `InitializeAsync` Runs when the marmalade which contains this canary is being loaded
|
|
|
|
|
- `DisposeAsync` Runs when the marmalade which contains this canary is being unloaded
|
