↳ | android.net.wifi.p2p.nsd.WifiP2pServiceRequest |
A class for creating a service discovery request for use with
WifiP2pManager#addServiceRequest
and WifiP2pManager#removeServiceRequest
This class is used to create service discovery request for custom
vendor specific service discovery protocol WifiP2pServiceInfo#SERVICE_TYPE_VENDOR_SPECIFIC
or to search all service protocols WifiP2pServiceInfo#SERVICE_TYPE_ALL
.
For the purpose of creating a UPnP or Bonjour service request, use
WifiP2pUpnpServiceRequest
or WifiP2pDnsSdServiceRequest
respectively.

Public methods
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
x
andy
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any non-null reference values
x
,y
, andz
, ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
. - It is consistent: for any non-null reference values
x
andy
, multiple invocations ofx.equals(y)
consistently returntrue
or consistently returnfalse
, provided no information used inequals
comparisons 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. |
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 inequals
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 thehashCode
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 thehashCode
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. |
newInstance
public static WifiP2pServiceRequest newInstance (int protocolType, String queryData)

Parameters | |
---|---|

or WifiP2pServiceInfo#SERVICE_TYPE_VENDOR_SPECIFIC .
In order to create a UPnP or Bonjour service request, use
WifiP2pUpnpServiceRequest or WifiP2pDnsSdServiceRequest
respectively |

or WifiP2pServiceInfo#SERVICE_TYPE_VENDOR_SPECIFIC .
In order to create a UPnP or Bonjour service request, use
WifiP2pUpnpServiceRequest or WifiP2pDnsSdServiceRequest
respectively |
Returns | |
