public Class<?> resolveClass(ObjectStreamClass classDesc) throws ClassNotFoundException, IOException Overrides java.io.ObjectInputStream.resolveClass. Doc from java.io.ObjectInputStream.resolveClass. Load the local class equivalent of the specified stream class description. Subclasses may implement this method to allow classes to be fetched from an alternate source. The corresponding method in `ObjectOutputStream` is `annotateClass`. This method will be invoked only once for each unique class in the stream. This method can be implemented by subclasses to use an alternate loading mechanism but must return a `Class` object. Once returned, if the class is not an array class, its serialVersionUID is compared to the serialVersionUID of the serialized class, and if there is a mismatch, the deserialization fails and an `InvalidClassException` is thrown. The default implementation of this method in `ObjectInputStream` returns the result of calling `Class.forName(desc.getName(), false, loader)` Class.forName(desc.getName(), false, loader) where `loader` is the first class loader on the current thread's stack (starting from the currently executing method) that is neither the platform class loader nor its ancestor; otherwise, `loader` is the platform class loader. If this call results in a `ClassNotFoundException` and the name of the passed `ObjectStreamClass` instance is the Java language keyword for a primitive type or void, then the `Class` object representing that primitive type or void will be returned (e.g., an `ObjectStreamClass` with the name `"int"` will be resolved to `Integer.TYPE`). Otherwise, the `ClassNotFoundException` will be thrown to the caller of this method. Parameters classDesc:ObjectStreamClass an instance of class `ObjectStreamClass` Returns:Class<?> a `Class` object corresponding to `desc` Annotations @Override Exceptions ClassNotFoundException: if class of a serialized object cannot be found.

public Class<?> resolveClass(ObjectStreamClass classDesc) throws ClassNotFoundException, IOException

Overrides java.io.ObjectInputStream.resolveClass.

Doc from java.io.ObjectInputStream.resolveClass.

Load the local class equivalent of the specified stream class description. Subclasses may implement this method to allow classes to be fetched from an alternate source.

The corresponding method in ObjectOutputStream is annotateClass. This method will be invoked only once for each unique class in the stream. This method can be implemented by subclasses to use an alternate loading mechanism but must return a Class object. Once returned, if the class is not an array class, its serialVersionUID is compared to the serialVersionUID of the serialized class, and if there is a mismatch, the deserialization fails and an InvalidClassException is thrown.

The default implementation of this method in ObjectInputStream returns the result of calling

Class.forName(desc.getName(), false, loader)

where loader is the first class loader on the current thread's stack (starting from the currently executing method) that is neither the platform class loader nor its ancestor; otherwise, loader is the platform class loader. If this call results in a ClassNotFoundException and the name of the passed ObjectStreamClass instance is the Java language keyword for a primitive type or void, then the Class object representing that primitive type or void will be returned (e.g., an ObjectStreamClass with the name "int" will be resolved to Integer.TYPE). Otherwise, the ClassNotFoundException will be thrown to the caller of this method.

Parameters

classDesc:ObjectStreamClass: an instance of class ObjectStreamClass

Returns:Class<?>

a Class object corresponding to desc

@Override

Exceptions

ClassNotFoundException:: if class of a serialized object cannot be found.
IOException:: any of the usual Input/Output exceptions.
