The ObjectStreamClass for a specific class loaded in this Java VM can
be found using the lookup method.
- Since:
- JDK1.1
forClass()
- Return the class in the local VM that this version is mapped to.
getField(String)
- Get the field of this class by name.
getFields()

public Class forClass()
- Return the class in the local VM that this version is mapped to.
Null is returned if there is no corresponding local class.
getFields
public ObjectStreamField[] getFields()
- Return an array of the fields of this serializable class.
- Returns:
