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.

Public Methods
public
Class<?>
forClass
()
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.
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.
Returns a collection of field descriptors for the serialized fields of
the class represented by this class descriptor.
Returns
- an array of field descriptors or an array of length zero if there
are no fields in this descriptor's class.
public
String
getName
()
Returns the name of the class represented by this descriptor.
Returns
- the fully qualified name of the class this descriptor represents.
public
long
getSerialVersionUID
()
Returns the Serial Version User ID of the class represented by this
descriptor.
Returns
- the SUID for the class represented by this descriptor.
Returns the descriptor corresponding to the class cl. If the
class is not serializable or externalizable then null is
returned.
Parameters
| cl
| a java.langClass for which to obtain the corresponding
descriptor |
Returns
- the corresponding descriptor if the
cl is serializable or
externalizable; null otherwise.
