WifiP2pConnectionInfo


public final class WifiP2pConnectionInfo
extends Object implements Parcelable

java.lang.Object
   ↳ android.net.wifi.p2p.WifiP2pConnectionInfo


A class representing the connection capabilities of a Wi-Fi P2P link.

This class provides information about the physical layer (PHY) of the connection, including the Wi-Fi standard in use (e.g. 802.11ax), the channel width, and the number of transmit and receive spatial streams (NSS). This data can be used to understand the performance characteristics of the P2P connection.

An instance of this class can be obtained from WifiP2pGroup or WifiP2pDevice.

Public methods

describeContents

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 writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

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

equals

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.

getChannelWidth

public int getChannelWidth ()

Gets the channel width of the current P2P connection.

Returns
int The channel width, as defined by the CHANNEL_WIDTH_* constants in ScanResult.
Value is one of the following:

getRxNss

public int getRxNss ()

Gets the maximum number of receive spatial streams (NSS) for the current P2P connection.

Returns
int The maximum number of spatial streams used for receiving data, or UNSPECIFIED if the value is not available.
Value is between 0 and 4 inclusive

getTxNss

public int getTxNss ()

Gets the maximum number of transmit spatial streams (NSS) for the current P2P connection.

Returns
int The maximum number of spatial streams used for transmitting data, or UNSPECIFIED if the value is not available.
Value is between 0 and 4 inclusive

getWifiStandard

public int getWifiStandard ()

Gets the Wi-Fi standard of the current P2P connection.

Returns
int The Wi-Fi standard, as defined by the WIFI_STANDARD_* constants in ScanResult.
Value is one of the following:

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 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 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.

toString

public String toString ()

Returns a string representation of the object.

Returns
String a string representation of the object.

writeToParcel

public void writeToParcel (Parcel parcel, 
                int flags)

Flatten this object in to a Parcel.

Parameters
parcel Parcel: This value cannot be null.

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 the following:
