  • Method Details

    • getInstance

      public static ASN1Sequence getInstance(Object obj)
      return an ASN1Sequence from the given object.
      Parameters:
      obj - the object we want converted.
      Throws:
      IllegalArgumentException - if the object cannot be converted.

    • getInstance

      public static ASN1Sequence getInstance(ASN1TaggedObject obj, boolean explicit)
      Return an ASN1 sequence from a tagged object. There is a special case here, if an object appears to have been explicitly tagged on reading but we were expecting it to be implictly tagged in the normal course of events it indicates that we lost the surrounding sequence - so we need to add it back (this will happen if the tagged object is a sequence that contains other sequences). If you are dealing with implicitly tagged sequences you really should be using this method.
      Parameters:
      obj - the tagged object.
      explicit - true if the object is meant to be explicitly tagged, false otherwise.
      Throws:
      IllegalArgumentException - if the tagged object cannot be converted.

    • getObjects

      public Enumeration getObjects()

    • parser

      public ASN1SequenceParser parser()

    • getObjectAt

      public DEREncodable getObjectAt(int index)
      return the object at the sequence postion indicated by index.
      Parameters:
      index - the sequence number (starting at zero) of the object
      Returns:
      the object at the sequence postion indicated by index.

    • size

      public int size()
      return the number of objects in this sequence.
      Returns:
      the number of objects in this sequence.
