implements Serializable

java.lang.Object
↳	java.io.ObjectStreamClass

Class Overview

Represents a descriptor for identifying a class during serialization and deserialization. Information contained in the descriptor includes the name and SUID of the class as well as field names and types. Information inherited from the superclasses is also taken into account.

Summary

Fields
public static final ObjectStreamField[]	NO_FIELDS	Constant indicating that the class has no Serializable fields.

Public Methods
Class<?>	forClass() Returns the class (java.lang.Class) for this descriptor.
ObjectStreamField	getField(String name) Gets a field descriptor of the class represented by this class descriptor.
ObjectStreamField[]	getFields() Returns a collection of field descriptors for the serialized fields of the class represented by this class descriptor.
String	getName() Returns the name of the class represented by this descriptor.
long	getSerialVersionUID() Returns the Serial Version User ID of the class represented by this descriptor.
static ObjectStreamClass	lookup(Class<?> cl) Returns the descriptor for a serializable class.
static ObjectStreamClass	lookupAny(Class<?> cl) Returns the descriptor for any class, whether or not the class implements Serializable or Externalizable.
String	toString() Returns a string containing a concise, human-readable description of this descriptor.

Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Constant indicating that the class has no Serializable fields.

Public Methods

public Class<?> forClass ()

Added in API level 1

Returns the class (java.lang.Class) for this descriptor.

Returns

the class in the local VM that this descriptor represents; null if there is no corresponding class.

public ObjectStreamField getField (String name)

Added in API level 1

Gets a field descriptor of the class represented by this class descriptor.

Parameters

name	the name of the desired field.

Returns

the field identified by name or null if there is no such field.

public ObjectStreamField[] getFields ()

Added in API level 1

Returns a collection of field descriptors for the serialized fields of the class represented by this class descriptor.

Returns
