Public constructors
UserHandle
UserHandle(in: Parcel!)
Instantiate a new UserHandle from the data in a Parcel that was previously written with writeToParcel(android.os.Parcel,int). Note that you must not use this with data written by writeToParcel(android.os.UserHandle,android.os.Parcel) since it is not possible to handle a null UserHandle here.
| Parameters | |
|---|---|
in |
Parcel!: The Parcel containing the previously written UserHandle, positioned at the location in the buffer where it was written. |
Public methods
describeContents
fun describeContents(): Int
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.
| Return | |
|---|---|
Int |
a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or
|
equals
fun equals(other: Any?): Boolean
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 | |
|---|---|
obj |
This value may be null. |
| Return | |
|---|---|
Boolean |
true if this object is the same as the obj argument; false otherwise. |
getUserHandleForUid
static fun getUserHandleForUid(uid: Int): UserHandle!
Returns the user for a given uid.
| Parameters | |
|---|---|
uid |
Int: A uid for an application running in a particular user. |
| Return | |
|---|---|
UserHandle! |
A UserHandle for that user. |
hashCode
fun hashCode(): Int
Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by java.util.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.
| Return | |
|---|---|
Int |
a hash code value for this object. |
readFromParcel
static fun readFromParcel(in: Parcel!): UserHandle!
Read a UserHandle from a Parcel that was previously written with writeToParcel(android.os.UserHandle,android.os.Parcel), returning either a null or new object as appropriate.
| Parameters | |
|---|---|
in |
Parcel!: The Parcel from which to read the UserHandle |
| Return | |
|---|---|
UserHandle! |
Returns a new UserHandle matching the previously written object, or null if a null had been written. |

toString
fun toString(): String
Returns a string representation of the object.
| Return | |
|---|---|
String |
a string representation of the object. |
writeToParcel
fun writeToParcel(
out: Parcel,
flags: Int
): Unit
Flatten this object in to a Parcel.
| Parameters | |
|---|---|
dest |
The Parcel in which the object should be written. This value cannot be null. |
flags |
Int: Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE. Value is either 0 or a combination of the following:
|
writeToParcel
static fun writeToParcel(
h: UserHandle!,
out: Parcel!
): Unit
Write a UserHandle to a Parcel, handling null pointers. Must be read with readFromParcel(android.os.Parcel).
| Parameters | |
|---|---|
h |
UserHandle!: The UserHandle to be written. |
out |
Parcel!: The Parcel in which the UserHandle will be placed. |
