Class ASN1TaggedObject

    • Field Detail

      • tagNo

        int tagNo
      • empty

        boolean empty
      • explicit

        boolean explicit
    • Constructor Detail

      • ASN1TaggedObject

        public ASN1TaggedObject​(int tagNo,
                                DEREncodable obj)
        Create a tagged object in the explicit style.
        Parameters:
        tagNo - the tag number for this object.
        obj - the tagged object.
      • ASN1TaggedObject

        public ASN1TaggedObject​(boolean explicit,
                                int tagNo,
                                DEREncodable obj)
        Create a tagged object with the style given by the value of explicit.

        If the object implements ASN1Choice the tag style will always be changed to explicit in accordance with the ASN.1 encoding rules.

        Parameters:
        explicit - true if the object is explicitly tagged.
        tagNo - the tag number for this object.
        obj - the tagged object.
    • Method Detail

      • getInstance

        public static ASN1TaggedObject getInstance​(java.lang.Object obj)
      • isExplicit

        public boolean isExplicit()
        return whether or not the object may be explicitly tagged.

        Note: if the object has been read from an input stream, the only time you can be sure if isExplicit is returning the true state of affairs is if it returns false. An implicitly tagged object may appear to be explicitly tagged, so you need to understand the context under which the reading was done as well, see getObject below.

      • isEmpty

        public boolean isEmpty()
      • getObject

        public DERObject getObject()
        return whatever was following the tag.

        Note: tagged objects are generally context dependent if you're trying to extract a tagged object you should be going via the appropriate getInstance method.

      • getObjectParser

        public DEREncodable getObjectParser​(int tag,
                                            boolean isExplicit)
        Return the object held in this tagged object as a parser assuming it has the type of the passed in tag. If the object doesn't have a parser associated with it, the base object is returned.
