jdk.io.ObjectStreamClass
Serialization's descriptor for classes. It contains the name and serialVersionUID of the class. The ObjectStreamClass for a specific class loaded in this Java VM can be found/created using the lookup method.
The algorithm to compute the SerialVersionUID is described in Object Serialization Specification, Section 4.6, Stream Unique Identifiers.

Static Constant. serialPersistentFields value indicating no serializable fields type: java.io.ObjectStreamField[]
*lookupclj
(*lookup cl)Find the descriptor for a class that can be serialized. Creates an ObjectStreamClass instance if one does not exist yet for class. Null is returned if the specified class does not implement java.io.Serializable or java.io.Externalizable.
cl - class for which to get the descriptor - java.lang.Class
returns: the class descriptor for the specified class - java.io.ObjectStreamClass
Find the descriptor for a class that can be serialized. Creates an ObjectStreamClass instance if one does not exist yet for class. Null is returned if the specified class does not implement java.io.Serializable or java.io.Externalizable. cl - class for which to get the descriptor - `java.lang.Class` returns: the class descriptor for the specified class - `java.io.ObjectStreamClass`
*lookup-anyclj
(*lookup-any cl)Returns the descriptor for any class, regardless of whether it implements Serializable.
cl - class for which to get the descriptor - java.lang.Class
returns: the class descriptor for the specified class - java.io.ObjectStreamClass
Returns the descriptor for any class, regardless of whether it implements Serializable. cl - class for which to get the descriptor - `java.lang.Class` returns: the class descriptor for the specified class - `java.io.ObjectStreamClass`
for-classclj
(for-class this)Return the class in the local VM that this version is mapped to. Null is returned if there is no corresponding local class.
returns: the Class instance that this descriptor represents - java.lang.Class<?>
Return the class in the local VM that this version is mapped to. Null is returned if there is no corresponding local class. returns: the Class instance that this descriptor represents - `java.lang.Class<?>`
get-fieldclj
(get-field this name)Get the field of this class by name.
name - the name of the data field to look for - java.lang.String
returns: The ObjectStreamField object of the named field or null if
there is no such named field. - java.io.ObjectStreamField
Get the field of this class by name.
name - the name of the data field to look for - `java.lang.String`
returns: The ObjectStreamField object of the named field or null if
there is no such named field. - `java.io.ObjectStreamField`get-fieldsclj
(get-fields this)Return an array of the fields of this serializable class.
returns: an array containing an element for each persistent field of
this class. Returns an array of length zero if there are no
fields. - java.io.ObjectStreamField[]
Return an array of the fields of this serializable class.
returns: an array containing an element for each persistent field of
this class. Returns an array of length zero if there are no
fields. - `java.io.ObjectStreamField[]`get-nameclj
(get-name this)Returns the name of the class described by this descriptor. This method returns the name of the class in the format that is used by the Class.getName() method.
returns: a string representing the name of the class - java.lang.String
Returns the name of the class described by this descriptor. This method returns the name of the class in the format that is used by the Class.getName() method. returns: a string representing the name of the class - `java.lang.String`
get-serial-version-uidclj
(get-serial-version-uid this)Return the serialVersionUID for this class. The serialVersionUID defines a set of classes all with the same name that have evolved from a common root class and agree to be serialized and deserialized using a common format. NonSerializable classes have a serialVersionUID of 0L.
returns: the SUID of the class described by this descriptor - long
Return the serialVersionUID for this class. The serialVersionUID defines a set of classes all with the same name that have evolved from a common root class and agree to be serialized and deserialized using a common format. NonSerializable classes have a serialVersionUID of 0L. returns: the SUID of the class described by this descriptor - `long`
to-stringclj
(to-string this)Return a string describing this ObjectStreamClass.
returns: a string representation of the object. - java.lang.String
Return a string describing this ObjectStreamClass. returns: a string representation of the object. - `java.lang.String`
