public class ErrorExtension

extends V3Extension

This class can be used to show extensions which can not be initialized because of an error.

An ErrorExtension only may be created when calling a listExtensions method that is based on the listExtensions() method of the X509Extensions class for obtaining an enumeration listing all the extensions included in, for instance, some particular certificate. The returned enumeration will contain an ErrorExtension for any extension which cannot be initialized because of some error (the DER encodig of the extension value is wrong, or the implementation is unable to parse the extension value).

An ErrorExtension always will be marked as being critical. It will contain the OID of the appertaining extension and can be queried for a message trying to explain the reason for the error.

Method Detail

toASN1Object

public ASN1Object toASN1Object()
                        throws X509ExtensionException

Only throws a X509ExtensionException, since an ErrorExtension only may be used for displaying information about some broken extension.

Overrides:

toASN1Object in class V3Extension

Throws:

X509ExtensionException - since an ErrorExtension only may be used for displaying information about some broken extension

init

public void init(ASN1Object obj)

Implements the V3Extension Interface. This method does nothing.

Overrides:

init in class V3Extension

Tags copied from class: V3Extension

Parameters:

obj - the extension value as ASN1Object

Throws:

X509ExtensionException - if the extension could not parse the ASN1Object

hashCode

public int hashCode()

Returns a hashcode for this identity.

Overrides:

hashCode in class V3Extension

Returns:

a hash code for this identity

getObjectID

public ObjectID getObjectID()

Returns the ObjectID of the broken extension.

Overrides:

getObjectID in class V3Extension

Returns:

the ObjectID of the broken extension

toString

public java.lang.String toString()

Returns a string that represents the contents of this ErrorExtension.

Overrides:

toString in class java.lang.Object

Returns:

the string representation
