Opaque object used to represent a Wi-Fi Aware peer. Obtained from discovery sessions in[DiscoverySessionCallback.onServiceDiscovered(PeerHandle, byte[], java.util.List)](https://developer.android.com/reference/android/net/wifi/aware/DiscoverySessionCallback#onServiceDiscovered(android.net.wifi.aware.PeerHandle,%20byte[],%20java.util.List))or received messages in[DiscoverySessionCallback.onMessageReceived(PeerHandle, byte[])](https://developer.android.com/reference/android/net/wifi/aware/DiscoverySessionCallback#onMessageReceived(android.net.wifi.aware.PeerHandle,%20byte[])), and used when sending messages e,g,[DiscoverySession.sendMessage(PeerHandle, int, byte[])](https://developer.android.com/reference/android/net/wifi/aware/DiscoverySession#sendMessage(android.net.wifi.aware.PeerHandle,%20int,%20byte[])), or when configuring a network link to a peer, e.g.[DiscoverySession.createNetworkSpecifierOpen(PeerHandle)](https://developer.android.com/reference/android/net/wifi/aware/DiscoverySession#createNetworkSpecifierOpen(android.net.wifi.aware.PeerHandle))or[DiscoverySession.createNetworkSpecifierPassphrase(PeerHandle, String)](https://developer.android.com/reference/android/net/wifi/aware/DiscoverySession#createNetworkSpecifierPassphrase(android.net.wifi.aware.PeerHandle,%20java.lang.String)).
Note that while a`PeerHandle`can be used to track a particular peer (i.e. you can compare the values received from subsequent messages) - it is good practice not to rely on it. Instead use an application level peer identifier encoded in the message,[DiscoverySession.sendMessage(PeerHandle, int, byte[])](https://developer.android.com/reference/android/net/wifi/aware/DiscoverySession#sendMessage(android.net.wifi.aware.PeerHandle,%20int,%20byte[])), and/or in the Publish configuration's service-specific information field,[PublishConfig.Builder.setServiceSpecificInfo(byte[])](https://developer.android.com/reference/android/net/wifi/aware/PublishConfig.Builder#setServiceSpecificInfo(byte[])), or match filter,[PublishConfig.Builder.setMatchFilter(java.util.List)](https://developer.android.com/reference/android/net/wifi/aware/PublishConfig.Builder#setMatchFilter(java.util.List)).
A parcelable handle object is available with[ParcelablePeerHandle](https://developer.android.com/reference/android/net/wifi/aware/ParcelablePeerHandle).

## Public methods
### equals
Added in[API level 26](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.
| Parameters ||
|-----|--------------------------------------------------------------|
| `o` | `Object`: the reference object with which to compare.
|
| Returns ||
|-----------|-------------------------------------------------------------------------------|
| `boolean` | `true`if this object is the same as the obj argument;`false`otherwise.
|
### hashCode
Added in[API level 26](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[HashMap](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[equals](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[equals](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.
| Returns ||
|-------|-------------------------------------------|
| `int` | a hash code value for this object.
