From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

public List<byte[]> getMatchFilters ()

Get the filter which resulted in this service discovery. For PublishConfig.PUBLISH_TYPE_UNSOLICITED, SubscribeConfig.SUBSCRIBE_TYPE_PASSIVE discovery sessions this is the publisher's match filter. For PublishConfig.PUBLISH_TYPE_SOLICITED, SubscribeConfig.SUBSCRIBE_TYPE_ACTIVE discovery sessions this is the subscriber's match filter.

Returns
`List<byte[]>`	A list of byte arrays representing the match filter. An empty list if match filter is not set. This value cannot be `null`.

Added in API level 34

public String getPairedAlias ()

Get the paired device alias if the discovered device has already paired. If not null device will automatically start the NAN pairing verification, DiscoverySessionCallback.onPairingVerificationSucceed(PeerHandle, String) will trigger when verification is finished

Returns
`String`

Added in API level 34

public AwarePairingConfig getPairingConfig ()

Get the discovered device's pairing config. Can be used for the following pairing setup or bootstrapping request.

Returns
`AwarePairingConfig`	This value may be `null`.

public int getPeerCipherSuite ()

Get the cipher suite type specified by the publish session to be used for data-path setup.

Returns
`int`	peerCipherSuite An integer represent the cipher suite used to encrypt the data-path. Value is either `0` or a combination of `Characteristics.WIFI_AWARE_CIPHER_SUITE_NONE`, `Characteristics.WIFI_AWARE_CIPHER_SUITE_NCS_SK_128`, `Characteristics.WIFI_AWARE_CIPHER_SUITE_NCS_SK_256`, `Characteristics.WIFI_AWARE_CIPHER_SUITE_NCS_PK_128`, and `Characteristics.WIFI_AWARE_CIPHER_SUITE_NCS_PK_256`

Added in API level 33

public PeerHandle getPeerHandle ()

Get the peer handle for the peer matching our discovery operation

Returns
`PeerHandle`	An opaque handle representing the discovered peer. This value cannot be `null`.

Added in API level 33

public byte[] getScid ()

Get the Security context identifier is associate with PMK for data path security config. Only use for Characteristics.WIFI_AWARE_CIPHER_SUITE_NCS_PK_128 and Characteristics.WIFI_AWARE_CIPHER_SUITE_NCS_PK_256 to get the PMKID set by WifiAwareDataPathSecurityConfig.Builder.setPmkId(byte[]) from publish session. This can help the Wi-Fi Aware data-path setup to select the correct PMK/PMKID

Returns
`byte[]`	An arbitrary byte array represent the security context identifier. `null` if Security context identifier is not set.

Added in API level 33

public byte[] getServiceSpecificInfo ()

The service specific information (arbitrary byte array) provided by the peer as part of its discovery configuration.

Returns
`byte[]`	An arbitrary byte array represent the service specific information. `null` if service specific information is not set.
