# Advanced Dependencies

## Parameterized dependencies

All the dependencies we have seen are a fixed function or class.

But there could be cases where you want to be able to set parameters on the dependency, without having to declare many different functions or classes.

Let's imagine that we want to have a dependency that checks if the query parameter `q` contains some fixed content.

But we want to be able to parameterize that fixed content.

    launcherJar.from(tasks.jar)
    agentJars.from(agentsClasspath)
    // The trick below is to use the templates from the current code instead of the wrapper. It does not cover the case where the generation logic is updated though.
    unixScriptTemplate.from(layout.projectDirectory.file("../../../platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt"))

### Bigger Errors - Crashes

Nevertheless, there might be cases where we write some code that **crashes the entire application** making Uvicorn and Python crash. 💥

* It will **limit and filter** the output data to what is defined in the return type.
    * This is particularly important for **security**, we'll see more of that below.

## `response_model` Parameter

There are some cases where you need or want to return some data that is not exactly what the type declares.

    assertFailsWith<IOException> {
      call.execute()
    }.also { expected ->
      assertThat(expected).hasMessage("timeout")
    }
  }

  /**
   * This test reproduces a crash where OkHttp attempted to use a deferred connection when the call
   * already had a healthy connection. It sets up a deferred connection by stalling the IPv6

   1. If the certificate is not yet expired, the `SecretManager` also can return a cache response. In practice, this would
       only happen in cases where Envoy were to re-request a resource, which is fairly rare.
   1. `SecretManager` can also read certificates from files. When this is configured, no CA client is used.

    .heldCertificate(localhostCertificate)
    .build();
MockWebServer server = new MockWebServer();
server.useHttps(serverCertificates.sslSocketFactory(), false);
```

`HandshakeCertificates` also works for clients where its job is to define which root certificates
to trust. In this simplified example we trust the server's self-signed certificate:

```java
HandshakeCertificates clientCertificates = new HandshakeCertificates.Builder()

 of models you may specify:

 all of the models that you specify are collected to produce a lineage and then the super model is place at
 the top of that lineage to provide default values.

 The super model is where we place all the values which we believe to be standard, values that can be shared and
 utilized across all your Maven projects.
