- All Implemented Interfaces:
- ASN1TaggedObjectParser, DEREncodable, DERTags
- Direct Known Subclasses:
- DERTaggedObject
public abstract class ASN1TaggedObject
- extends ASN1Object
- implements ASN1TaggedObjectParser
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).

tagNo
int tagNo
empty
boolean empty
explicit
boolean explicit
obj
DEREncodable obj
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.
getInstance
public static ASN1TaggedObject getInstance(ASN1TaggedObject obj,
boolean explicit)
getInstance
public static ASN1TaggedObject getInstance(java.lang.Object obj)
asn1Equals
boolean asn1Equals(DERObject o)
- Specified by:
asn1Equals
in class ASN1Object
hashCode
public int hashCode()
- Specified by:
hashCode
in class ASN1Object
getTagNo
public int getTagNo()
- Specified by:
getTagNo
in interface ASN1TaggedObjectParser
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.
- Specified by:
getObjectParser
in interface ASN1TaggedObjectParser
encode
abstract void encode(DEROutputStream out)
throws java.io.IOException
- Specified by:

in class ASN1Object
- Throws:
java.io.IOException
