    DEREncodable obj) 
{
        this.explicit = true;
        this.tagNo = tagNo;
        this.obj = obj;
}

Create a tagged object in the explicit style.

Parameters:

tagNo - the tag number for this object.

obj - the tagged object.

 public ASN1TaggedObject(boolean explicit,
    int tagNo,
    DEREncodable obj) 
{
        if (obj instanceof ASN1Choice)
        {
            this.explicit = true;
        }
        else
        {
            this.explicit = explicit;
        }
        this.tagNo = tagNo;
        this.obj = 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.

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.

 public boolean isEmpty() 
{

}

 public boolean isExplicit() 
{
        return explicit;
}

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.
