## Fields

### CREATOR

Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static final Creator<WifiP2pUsdBasedServiceConfig> CREATOR
```

Implement the Parcelable interface

<br />

## Public constructors

### WifiP2pUsdBasedServiceConfig

Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public WifiP2pUsdBasedServiceConfig ()
```

<br />

<br />

## Public methods

### describeContents

Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int describeContents ()
```

Implement the Parcelable interface

<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 36](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`: the reference object with which to compare. <br /> |

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

### getMaxAllowedServiceSpecificInfoLength

Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static int getMaxAllowedServiceSpecificInfoLength ()
```

Maximum allowed length of service specific information that can be set in the USD service configuration. See also `https://developer.android.com/reference/android/net/wifi/p2p/nsd/WifiP2pUsdBasedServiceConfig.Builder#setServiceSpecificInfo(byte[])`.

<br />

| Returns ||
|---|---|
| `int` | <br /> |

### getServiceName

Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public String getServiceName ()
```

Get the service name of this USD service configuration. See also `https://developer.android.com/reference/android/net/wifi/p2p/nsd/WifiP2pUsdBasedServiceConfig.Builder`.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | UTF-8 string defining the service. This value cannot be `null`. <br /> |

### getServiceProtocolType

Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int getServiceProtocolType ()
```

Get the service protocol type of this USD service configuration. See also `https://developer.android.com/reference/android/net/wifi/p2p/nsd/WifiP2pUsdBasedServiceConfig.Builder#setServiceProtocolType(int)`.

<br />

| Returns ||
|---|---|
| `int` | A non-negative service layer protocol type. Value is between 0 and 255 inclusive <br /> |

### getServiceSpecificInfo

Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public byte[] getServiceSpecificInfo ()
```

Get the service specific info of this USD service configuration. See also `https://developer.android.com/reference/android/net/wifi/p2p/nsd/WifiP2pUsdBasedServiceConfig.Builder#setServiceSpecificInfo(byte[])` .

<br />

| Returns ||
|---|---|
| `byte[]` | A byte-array of service specification information, or null if unset. <br /> |

### hashCode

Added in [API level 36](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 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public String toString ()
```

Generates a string of all the defined elements.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | a compiled string representing all elements <br /> |

### writeToParcel

Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

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

Implement the Parcelable interface

<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` |
