Introduction
Java.io SerializablePermission - The serializable is the class which represents a target name and it is the name of Java.io SerializablePermission. Java.io SerializablePermission class is declared below:
Public final class SerializablePermission extends Basic Permission Table
| Constructor | Description |
|---|---|
| SerializablePermission(String name) | The function of this constructor is to create a new Java.io SerializablePermission with represented name. |
| SerializablePermission(String name, String actions) | The function of this constructor is to create a new Java.io SerializablePermission instance with represented name and action. |
Description
From the following classes, methods are inherited to the Java.io SerializablePermission class.
- Java.io.Object
- Java.io.BasicPermission
- Java.io.Permission
Example
Following is an source code for Java.io SerializablePermission.
SerializablePermission.java
[java]import java.security.BasicPermission;
/**
* This class models permissions related to serialization. As a subclass
* of <code>BasicPermission</code>, this class has permissions that have
* a name only. There is no associated action list.
* <p>
* There are currently two allowable permission names for this class:
* <ul>
* <li><code>enableSubclassImplementation</code> - Allows a subclass to
* override the default serialization behavior of objects.
* <li><code>enableSubstitution</code> - Allows substitution of one object
* for another during serialization or deserialization.
