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.

Fields
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 returntrue. - It is symmetric: for any non-null reference values
xandy,x.equals(y)should returntrueif and only ify.equals(x)returnstrue. - It is transitive: for any non-null reference values
x,y, andz, ifx.equals(y)returnstrueandy.equals(z)returnstrue, thenx.equals(z)should returntrue. - It is consistent: for any non-null reference values
xandy, multiple invocations ofx.equals(y)consistently returntrueor consistently returnfalse, provided no information used inequalscomparisons on the objects is modified. - For any non-null reference value
x,x.equals(null)should returnfalse.
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
hashCodemethod must consistently return the same integer, provided no information used inequalscomparisons 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
equalsmethod, then calling thehashCodemethod 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
equalsmethod, then calling thehashCodemethod 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:
