      public class GeneralSubtree
      extends ASN1Object

  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(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

    - #### getInstance

          public static GeneralSubtree getInstance(java.lang.Object obj)

    - #### getBase

          public GeneralName getBase()

    - #### getMinimum

          public java.math.BigInteger getMinimum()

    - #### getMaximum

          public java.math.BigInteger getMaximum()

    - #### toASN1Primitive
