DERTaggedObject
ASN.1 TaggedObject - in ASN.1 nottation this is any object proceeded by
a [n] where n is some number - these are assume to follow the construction
rules (as with sequences).

ASN1TaggedObject
Create a tagged object in the explicit style.- Parameters:
tagNo
- the tag number for this object.obj
- the tagged object.
-
ASN1TaggedObject
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.

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
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
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.- Specified by:
