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 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 | |
---|---|
obj |
Object : This value may be null . |
Returns | |
---|---|
boolean |
true if this object is the same as the obj
argument; false otherwise. |
getSessionId
public String getSessionId ()
Retrieves the Session Key
The session key is an ephemeral key uniquely identifying the session for a Platform VPN. The lifetime of this key is tied to the lifetime of the VPN session. In other words, reprovisioning of the VPN profile, restarting of the device, or manually restarting the platform VPN session will result in a new VPN session, and a new key.
Returns | |
---|---|
String |
the unique key for the platform VPN session, or null if it is not running. |
getState
public int getState ()
Returns the state of the Platform VPN
This state represents the internal connection state of the VPN. This state may diverge from the VPN Network's state during error and recovery handling.
Returns | |
---|---|
int |
Value is STATE_CONNECTED , STATE_CONNECTING , STATE_DISCONNECTED , or STATE_FAILED |
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. |
isAlwaysOn
public boolean isAlwaysOn ()
Returns the always-on status of the PlatformVpnProfile.
If the PlatformVpnProfile is set to be running in always-on mode, the system will ensure that the profile is always started, and restarting it when necessary (e.g. after reboot).
Always-on can be set by an appropriately privileged user via the Settings VPN menus, or by the Device Policy Manager app programmatically. See DevicePolicyManager#setAlwaysOnVpnPackage(ComponentName, String, boolean, Set)
Returns | |
---|---|
boolean |
isLockdownEnabled
public boolean isLockdownEnabled ()
Returns the lockdown mode status of the PlatformVpnProfile.
In lockdown mode, the system will ensure that apps are not allowed to bypass the VPN, including during startup or failure of the VPN.
Lockdown mode can be set by an appropriately privileged user via the Settings VPN menus, or by the Device Policy Manager app programmatically. See DevicePolicyManager#setAlwaysOnVpnPackage(ComponentName, String, boolean, Set)
Returns | |
---|---|
boolean |
toString
public String toString ()
Returns a string representation of the object.
Returns | |
---|---|
String |
a string representation of the object. |
writeToParcel
public void writeToParcel (Parcel out, int flags)
Implement the Parcelable interface
Parameters | |
---|---|
out |
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 Parcelable.PARCELABLE_WRITE_RETURN_VALUE , and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
