oracle.security.crypto.cert
Class X509ExtensionSet

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

All Implemented Interfaces:

java.io.Externalizable, java.io.Serializable, oracle.security.crypto.asn1.ASN1Object, oracle.security.crypto.util.Streamable

public class X509ExtensionSet

extends java.lang.Object

implements oracle.security.crypto.asn1.ASN1Object, java.io.Externalizable

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.

X509Extension, Serialized Form

Constructor Summary

X509ExtensionSet()
Create a new, empty X509ExtensionSet.

X509ExtensionSet(java.io.InputStream is)
Create a new X509ExtensionSet from the given input stream.

X509ExtensionSet(java.util.Vector exts)
Create a new X509ExtensionSet containing the X509Extensionss in the given vector.

Method Summary

X509Extension	addExtension(X509Extension ext) Add an extension to this extension set.
X509Extension	getExtension(oracle.security.crypto.asn1.ASN1ObjectID type) Returns the extension with the given type.
java.util.Vector	getExtensions() Returns a vector of all the extensions contained in this X509ExtensionSet.
boolean	hasExtension(oracle.security.crypto.asn1.ASN1ObjectID type) Returns true if this X509ExtensionSet contains an extension of the given type, otherwise returns false.
boolean	hasUnrecognizedCriticalExtension() Returns true if this X509ExtensionSet contains a critical extension that is not recognized by this implementation.
void	input(java.io.InputStream is)
int	length() Returns the length in bytes of the ASN.1 representation of this X509ExtensionSet.
void	output(java.io.OutputStream os)
void	readExternal(java.io.ObjectInput is)
int	size() Returns the number of extensions in this X509ExtensionSet.
java.lang.String	toString()
java.util.Enumeration	types() Returns an enumeration of the types of all the extensions contained in this X509ExtensionSet.
