Class DisplayText

java.lang.Object
  org.gudy.bouncycastle.asn1.ASN1Encodable
      org.gudy.bouncycastle.asn1.x509.DisplayText

All Implemented Interfaces:

ASN1Choice, DEREncodable

public class DisplayText
extends ASN1Encodable
implements ASN1Choice

DisplayText class, used in CertificatePolicies X509 V3 extensions (in policy qualifiers).

It stores a string in a chosen encoding.

 DisplayText ::= CHOICE {
      ia5String        IA5String      (SIZE (1..200)),
      visibleString    VisibleString  (SIZE (1..200)),
      bmpString        BMPString      (SIZE (1..200)),
      utf8String       UTF8String     (SIZE (1..200)) }
