类 NotificationSorting

java.lang.Object

ohos.event.notification.NotificationSorting

所有已实现的接口:

Sequenceable

public class NotificationSorting
extends Object
implements Sequenceable

Provides sorting information about an active notification.

When a new notification arrives, the sorting of existing active notifications such as their respective priority or time order will change, and the sorting information about the current notification will change accordingly. This information is only a snapshot and changes in real time. You can only obtain but cannot set information in this class.

public String getGroupKeyOverride()

Obtains the overridden notification group key. If the system has overridden the group key, a non-null value will be returned.

返回:

Returns the overridden notification group key used to bind notifications.

从以下版本开始:

getVisiblenessOverride

public int getVisiblenessOverride()

Obtains the visibility of the current notification on the lock screen set in the corresponding NotificationSlot.

返回:

Returns the visibility of the notification on the lock screen.

marshalling

public boolean marshalling(Parcel out)

Marshals a NotificationSorting object into a Parcel.

A process can call the unmarshalling(ohos.utils.Parcel) method to unmarshal a NotificationSorting object from a Parcel to implement inter-process communication (IPC).

指定者:

marshalling 在接口中 Sequenceable

参数:

out - Indicates the Parcel object for marshalling.

返回:

Returns true if the marshalling is successful; returns false otherwise.

从以下版本开始:

2

unmarshalling

public boolean unmarshalling(Parcel in)

Unmarshals a NotificationSorting object from a Parcel.

指定者:

unmarshalling 在接口中 Sequenceable

参数:

in - Indicates the Parcel object for unmarshalling.

返回:

Returns true if the unmarshalling is successful; returns false otherwise.

toString

public String toString()

从类复制的说明: Object

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

覆盖:

toString 在类中 Object

返回:

a string representation of the object.
