X509ExtensionSet (Oracle® Fusion Middleware Java API Reference for Oracle Security Developer Tools)

java.lang.Object
- oracle.security.crypto.cert.X509ExtensionSet

All Implemented Interfaces:

java.io.Externalizable, java.io.Serializable, java.security.cert.X509Extension
```
public class X509ExtensionSet
extends java.lang.Object
implements java.io.Externalizable, java.security.cert.X509Extension
```
A list of X.509 Extensions, as defined in RFC 2459.
The list has hashtable semantics in that at most one extension of a given type may be defined at any given time, but has vector semantics in that order of input is preserved.
