Marshals this ConversationalMessage object into a Parcel.

A process can call the unmarshalling(ohos.utils.Parcel) method to unmarshal this ConversationalMessage 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:

public boolean unmarshalling(Parcel in)

Unmarshals this ConversationalMessage object from a Parcel.

指定者:

unmarshalling 在接口中 Sequenceable

参数:

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.
