public static final Creator<TrafficDescriptor> CREATOR
```

<br />

<br />

## Public methods

### describeContents

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

```
public int describeContents ()
```

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/android/os/Parcelable#writeToParcel(android.os.Parcel,%20int)`, the return value of this method must include the `https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR` bit.

<br />

| Returns ||
|---|---|
| `int` | 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/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR` |

### equals

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

```
public boolean equals (Object o)
```

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.

<br />

| Parameters ||
|---|---|
| `o` | `Object`: This value may be `null`. <br /> |

| Returns ||
|---|---|
| `boolean` | `true` if this object is the same as the obj argument; `false` otherwise. <br /> |

### getConnectionCapability

Added in [API level 37](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int getConnectionCapability ()
```

Get the connection capability of the traffic.

The connection capability indicates the type of traffic. The values are defined in 3GPP TS 24.526, Table 5.2.1. This is used by the network for UE Route Selection Policy (URSP) traffic matching.

When used to request a data connection, the framework may only use one specific connection capability to match a network capability, even if the underlying APN supports multiple (e.g., both internet and MMS). In such cases, only the single matched connection capability from the network request will be sent to the modem.

<br />

| Returns ||
|---|---|
| `int` | The connection capability, as one of the `CONNECTION_CAPABILITY_*` constants. Returns `https://developer.android.com/reference/android/telephony/data/TrafficDescriptor#CONNECTION_CAPABILITY_UNKNOWN` if not specified. Value is one of the following: - `https://developer.android.com/reference/android/telephony/data/TrafficDescriptor#CONNECTION_CAPABILITY_UNKNOWN` - `https://developer.android.com/reference/android/telephony/data/TrafficDescriptor#CONNECTION_CAPABILITY_IMS` - `https://developer.android.com/reference/android/telephony/data/TrafficDescriptor#CONNECTION_CAPABILITY_MMS` - `https://developer.android.com/reference/android/telephony/data/TrafficDescriptor#CONNECTION_CAPABILITY_SUPL` - `https://developer.android.com/reference/android/telephony/data/TrafficDescriptor#CONNECTION_CAPABILITY_INTERNET` - `https://developer.android.com/reference/android/telephony/data/TrafficDescriptor#CONNECTION_CAPABILITY_LCS_USER_PLANE_POSITIONING` - `https://developer.android.com/reference/android/telephony/data/TrafficDescriptor#CONNECTION_CAPABILITY_IOT_DELAY_TOLERANT` - `https://developer.android.com/reference/android/telephony/data/TrafficDescriptor#CONNECTION_CAPABILITY_IOT_NON_DELAY_TOLERANT` - `https://developer.android.com/reference/android/telephony/data/TrafficDescriptor#CONNECTION_CAPABILITY_DOWNLINK_STREAMING` - `https://developer.android.com/reference/android/telephony/data/TrafficDescriptor#CONNECTION_CAPABILITY_UPLINK_STREAMING` - `https://developer.android.com/reference/android/telephony/data/TrafficDescriptor#CONNECTION_CAPABILITY_VEHICULAR_COMMUNICATIONS` - `https://developer.android.com/reference/android/telephony/data/TrafficDescriptor#CONNECTION_CAPABILITY_REAL_TIME_INTERACTIVE` - `https://developer.android.com/reference/android/telephony/data/TrafficDescriptor#CONNECTION_CAPABILITY_UNIFIED_COMMUNICATIONS` - `https://developer.android.com/reference/android/telephony/data/TrafficDescriptor#CONNECTION_CAPABILITY_BACKGROUND` - `https://developer.android.com/reference/android/telephony/data/TrafficDescriptor#CONNECTION_CAPABILITY_MISSION_CRITICAL_COMMUNICATIONS` - `https://developer.android.com/reference/android/telephony/data/TrafficDescriptor#CONNECTION_CAPABILITY_TIME_CRITICAL_COMMUNICATIONS` - `https://developer.android.com/reference/android/telephony/data/TrafficDescriptor#CONNECTION_CAPABILITY_LOW_LATENCY_LOSS_TOLERANT_UNACK` |

### getDataNetworkName

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

```
public String getDataNetworkName ()
```

DNN stands for Data Network Name and represents an APN as defined in 3GPP TS 23.003.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | the DNN of this traffic descriptor if one is included by the network, null otherwise. <br /> |

### getOsAppId

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

```
public byte[] getOsAppId ()
```

OsAppId identifies a broader traffic category. Although it names Os/App id, it only includes OS version with a general/broader category id used as app id.

<br />

| Returns ||
|---|---|
| `byte[]` | The id in byte format. `null` if not available. <br /> |

### hashCode

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

```
public int hashCode ()
```

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/java/util/HashMap`.

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/java/lang/Object#equals(java.lang.Object)` 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/java/lang/Object#equals(java.lang.Object)` 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.

<br />

<br />

| Returns ||
|---|---|
| `int` | a hash code value for this object. <br /> |

### toString

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

```
public String toString ()
```

Returns a string representation of the object.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | This value cannot be `null`. <br /> |

### writeToParcel

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

```
public void writeToParcel (Parcel dest, 
                int flags)
```

Flatten this object in to a Parcel.

<br />

| Parameters ||
|---|---|
| `dest` | `Parcel`: This value cannot be `null`. <br /> |
| `flags` | `int`: Additional flags about how the object should be written. May be 0 or `https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of the following: - `https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE` |
