## What is "Dependency Injection" { #what-is-dependency-injection }

**"Dependency Injection"** means, in programming, that there is a way for your code (in this case, your *path operation functions*) to declare things that it requires to work and use: "dependencies".

And then, that system (in this case **FastAPI**) will take care of doing whatever is needed to provide your code with those needed dependencies ("inject" the dependencies).

![Events Diagram](../assets/images/******@****.***)

Here’s a [sample event listener](https://github.com/square/okhttp/blob/master/samples/guide/src/main/java/okhttp3/recipes/PrintEventsNonConcurrent.java) that prints each event with a timestamp.

```java
class PrintingEventListener extends EventListener {
  private long callStartNanos;

  private void printEvent(String name) {
    long nowNanos = System.nanoTime();

import static java.lang.annotation.RetentionPolicy.RUNTIME;

 * It's currently implemented by two use cases:
 * 1. Collect cache misses for compilation tasks and publish a `CACHE_MISS` tag for a Build Scan.
 * 2. Collect failed task paths and display a link which points to the corresponding task in the Build Scan, like `https://ge.gradle.org/s/xxx/console-log?task=yyy`.
