Class GeneralSubtree

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

All Implemented Interfaces:

DEREncodable

public class GeneralSubtree
extends ASN1Encodable

Class for containing a restriction object subtrees in NameConstraints. See RFC 3280.

       
       GeneralSubtree ::= SEQUENCE 
       {
         base                    GeneralName,
         minimum         [0]     BaseDistance DEFAULT 0,
         maximum         [1]     BaseDistance OPTIONAL 
       }

Constructor Detail

GeneralSubtree

public GeneralSubtree(ASN1Sequence seq)

GeneralSubtree

public GeneralSubtree(GeneralName base,
                      java.math.BigInteger minimum,
                      java.math.BigInteger maximum)

Constructor from a given details. According RFC 3280, the minimum and maximum fields are not used with any name forms, thus minimum MUST be zero, and maximum MUST be absent.

If minimum is null, zero is assumed, if maximum is null, maximum is absent.

Parameters:

base - A restriction.

minimum - Minimum

maximum - Maximum

toASN1Object

public DERObject toASN1Object()

Produce an object suitable for an ASN1OutputStream. Returns:

         maximum         [1]     BaseDistance OPTIONAL 
       }
 

Specified by:

toASN1Object in class ASN1Encodable

Returns:

a DERObject
