Fields

CREATOR

public static final Creator<WifiP2pDevice> CREATOR

Implement the Parcelable interface

deviceAddress

public String deviceAddress

The device MAC address uniquely identifies a Wi-Fi p2p device

deviceName

public String deviceName

The device name is a user friendly string to identify a Wi-Fi p2p device

primaryDeviceType

public String primaryDeviceType

Primary device type identifies the type of device. For example, an application could filter the devices discovered to only display printers if the purpose is to enable a printing action from the user. See the Wi-Fi Direct technical specification for the full list of standard device types supported.

secondaryDeviceType

public String secondaryDeviceType

Secondary device type is an optional attribute that can be provided by a device in addition to the primary device type.

status

public int status

Device connection status

Public constructors

WifiP2pDevice

public WifiP2pDevice ()

WifiP2pDevice

public WifiP2pDevice (WifiP2pDevice source)

copy constructor

Parameters
`source`	`WifiP2pDevice`

Public methods

describeContents

public int describeContents ()

Implement the Parcelable interface

Returns
`int`	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

equals

public boolean equals (Object obj)

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.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Parameters
`obj`	`Object`: the reference object with which to compare.

Returns
`boolean`	`true` if this object is the same as the obj argument; `false` otherwise.

getWfdInfo

public WifiP2pWfdInfo getWfdInfo ()

The Wifi Display information for this device, or null if unavailable.

Returns
`WifiP2pWfdInfo`

hashCode

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.

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(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(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.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Returns
`int`	a hash code value for this object.

isGroupOwner

public boolean isGroupOwner ()

Returns true if the device is a group owner

Returns
`boolean`

isServiceDiscoveryCapable

public boolean isServiceDiscoveryCapable ()

Returns true if the device is capable of service discovery

Returns
`boolean`

toString

public String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())

Returns
`String`	a string representation of the object.

update

public void update (WifiP2pDevice device)

Update this device's details using another WifiP2pDevice instance. This will throw an exception if the device address does not match.

Parameters
`device`	`WifiP2pDevice`: another instance of `WifiP2pDevice` used to update this instance. This value cannot be `null`.

Throws
`IllegalArgumentException`	if the device is null or the device address does not match

wpsDisplaySupported

public boolean wpsDisplaySupported ()

Returns true if WPS display configuration is supported

Returns
`boolean`

wpsKeypadSupported

public boolean wpsKeypadSupported ()

Returns true if WPS keypad configuration is supported

Returns
`boolean`

wpsPbcSupported

public boolean wpsPbcSupported ()

Returns true if WPS push button configuration is supported

Returns
`boolean`

writeToParcel

public void writeToParcel (Parcel dest, 
                int flags)

Implement the Parcelable interface

Parameters
`dest`	`Parcel`: The Parcel in which the object should be written.
`flags`	`int`: Additional flags about how the object should be written. May be 0 or `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
