# WireBox Event Model

WireBox also sports a very nice event model that can announce several object life cycle events. You can listen to these events and interact with WireBox at runtime very easily, whether you are in standalone mode or within a ColdBox application.

> **Note** If you are within a ColdBox application, you get the benefit of all the potential of [ColdBox Interceptors](https://coldbox.ortusbooks.com/full/interceptors/interceptors.html) and if you are in standalone mode, well, you just get the listener and that's it.

Each event execution also comes with a structure of name-value pairs called `interceptData` that can contain objects, variables and all kinds of data that can be useful for listeners to use. This data is sent by the event caller and each event caller decides what this data sent is. Also, remember that WireBox also can be ran with a reference to [CacheBox](https://cachebox.ortusbooks.com), which also offers lots of internal events that you can tap into. So let's start investigating first the object life cycle events.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://wirebox.ortusbooks.com/2/usage/wirebox-event-model.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
