This class represents a configuration for a Virtual Carrier Network.

Each `https://developer.android.com/reference/kotlin/android/net/vcn/VcnGatewayConnectionConfig` instance added represents a connection that will be brought up on demand based on active `https://developer.android.com/reference/kotlin/android/net/NetworkRequest.html#`(s).

## Public methods

### describeContents

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)

```
fun describeContents(): Int
```

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of `https://developer.android.com/reference/kotlin/android/os/Parcelable.html#writeToParcel(android.os.Parcel,%20kotlin.Int)`, the return value of this method must include the `https://developer.android.com/reference/kotlin/android/os/Parcelable.html#CONTENTS_FILE_DESCRIPTOR:kotlin.Int` bit.

| Return ||
|---|---|
| `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or - `https://developer.android.com/reference/kotlin/android/os/Parcelable.html#CONTENTS_FILE_DESCRIPTOR:kotlin.Int` |

### equals

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)

```
fun equals(other: Any?): Boolean
```

Indicates whether some other object is "equal to" this one.

The `equals` method implements an equivalence relation on non-null object references:

- It is *reflexive* : for any non-null reference value `x`, `x.equals(x)` should return `true`.
- It is *symmetric* : for any non-null reference values `x` and `y`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`.
- It is *transitive* : for any non-null reference values `x`, `y`, and `z`, if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`.
- It is *consistent* : for any non-null reference values `x` and `y`, multiple invocations of `x.equals(y)` consistently return `true` or consistently return `false`, provided no information used in `equals` comparisons on the objects is modified.
- For any non-null reference value `x`, `x.equals(null)` should return `false`.

An equivalence relation partitions the elements it operates on into *equivalence classes*; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

| Parameters ||
|---|---|
| `obj` | the reference object with which to compare. |
| `other` | [Any](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-any/index.html)?: This value may be `null`. |

| Return ||
|---|---|
| `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html` | `true` if this object is the same as the obj argument; `false` otherwise. |

### getGatewayConnectionConfigs

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)

```
fun getGatewayConnectionConfigs(): MutableSet<VcnGatewayConnectionConfig!>
```

Retrieves the set of configured GatewayConnection(s).

| Return ||
|---|---|
| `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-mutable-set/index.html<https://developer.android.com/reference/kotlin/android/net/vcn/VcnGatewayConnectionConfig!>` | This value cannot be `null`. |

### getRestrictedUnderlyingNetworkTransports

Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)

```
fun getRestrictedUnderlyingNetworkTransports(): MutableSet<Int!>
```

Retrieve the transports that will be restricted by the VCN.

| Return ||
|---|---|
| `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-mutable-set/index.html<https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html!>` | This value cannot be `null`. |

### hashCode

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)

```
fun hashCode(): Int
```

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by `https://developer.android.com/reference/kotlin/java/util/HashMap.html#`.

The general contract of `hashCode` is:

- Whenever it is invoked on the same object more than once during an execution of a Java application, the `hashCode` method must consistently return the same integer, provided no information used in `equals` comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
- If two objects are equal according to the `https://developer.android.com/reference/kotlin/java/lang/Object.html#equals(kotlin.Any)` method, then calling the `hashCode` method on each of the two objects must produce the same integer result.
- It is *not* required that if two objects are unequal according to the `https://developer.android.com/reference/kotlin/java/lang/Object.html#equals(kotlin.Any)` method, then calling the `hashCode` method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

| Return ||
|---|---|
| `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html` | a hash code value for this object. |

### writeToParcel

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)

```
fun writeToParcel(
    out: Parcel, 
    flags: Int
): Unit
```

Flatten this object in to a Parcel.

| Parameters ||
|---|---|
| `dest` | The Parcel in which the object should be written. This value cannot be `null`. |
| `flags` | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html): Additional flags about how the object should be written. May be 0 or `https://developer.android.com/reference/kotlin/android/os/Parcelable.html#PARCELABLE_WRITE_RETURN_VALUE:kotlin.Int`. Value is either `0` or a combination of the following: - `https://developer.android.com/reference/kotlin/android/os/Parcelable.html#PARCELABLE_WRITE_RETURN_VALUE:kotlin.Int` |
| `out` | [Parcel](https://developer.android.com/reference/kotlin/android/os/Parcel.html#): This value cannot be `null`. |
