java.lang.Object | |
↳ | 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 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:
x
, x.equals(x)
should return
true
.
x
and y
, x.equals(y)
should return true
if and only if
y.equals(x)
returns true
.
x
, y
, and z
, if
x.equals(y)
returns true
and
y.equals(z)
returns true
, then
x.equals(z)
should return true
.
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.
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 | |
---|---|
o |
Object : the reference object with which to compare. |
Returns | |
---|---|
boolean |
true if this object is the same as the obj
argument; false otherwise. |
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:
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.
equals(Object)
method, then calling the hashCode
method on each of
the two objects must produce the same integer result.
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.)

int |
a hash code value for this object. |
public static WifiP2pServiceRequest newInstance (int protocolType, String queryData)
Create a service discovery request.
Parameters | |
---|---|

int : can be WifiP2pServiceInfo#SERVICE_TYPE_ALL
or WifiP2pServiceInfo#SERVICE_TYPE_VENDOR_SPECIFIC .
In order to create a UPnP or Bonjour service request, use
WifiP2pUpnpServiceRequest or WifiP2pDnsSdServiceRequest
respectively |
queryData |
String : hex string that is vendor specific. Can be null. |
Returns | |
---|---|
WifiP2pServiceRequest |
service discovery request. |
public static WifiP2pServiceRequest newInstance (int protocolType)

Parameters | |
---|---|
protocolType |
int : can be WifiP2pServiceInfo#SERVICE_TYPE_ALL
or WifiP2pServiceInfo#SERVICE_TYPE_VENDOR_SPECIFIC .
In order to create a UPnP or Bonjour service request, use
WifiP2pUpnpServiceRequest or WifiP2pDnsSdServiceRequest
respectively |
Returns | |
