public class ObjectStreamField extends Object implements Comparable
A description of a Serializable field from a Serializable class. An array of ObjectStreamFields is used to declare the Serializable fields of a class.
Constructor Summary | |
---|---|
ObjectStreamField(String name, Class type) Create a Serializable field with the specified type. |
|
ObjectStreamField(String name, Class type, boolean unshared) Creates an ObjectStreamField representing a serializable field with the given name and type. |
Method Summary | |
---|---|
int |
Compare this field with another ObjectStreamField .
|
String |
getName() Get the name of this field. |
int |
Offset of field within instance data. |
Class |
getType() Get the type of the field. |
char |
Returns character encoding of field type. |
String |
Return the JVM type signature. |
boolean |
Return true if this field has a primitive type. |
boolean |
Returns boolean value indicating whether or not the serializable field represented by this ObjectStreamField instance is unshared. |

public int compareTo(Object obj)
ObjectStreamField
. Return
-1 if this is smaller, 0 if equal, 1 if greater. Types that are
primitives are "smaller" than object types. If equal, the field names
are compared.
