Class ASN1TaggedObject
java.lang.Object
com.lowagie.bc.asn1.DERObject
com.lowagie.bc.asn1.ASN1TaggedObject
- All Implemented Interfaces:
- DEREncodable, DERTags
- Direct Known Subclasses:
- DERTaggedObject
public abstract class ASN1TaggedObject
- extends DERObject
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)
- Parameters:
tagNo
- the tag number for this object.obj
- the tagged object.
ASN1TaggedObject
public ASN1TaggedObject(boolean explicit,
int tagNo,
DEREncodable obj)
- 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)
equals
public boolean equals(java.lang.Object o)
- Overrides:
equals
in class java.lang.Object
hashCode
public int hashCode()
- Overrides:
hashCode
in class java.lang.Object
getTagNo
public int getTagNo()
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.
encode
abstract void encode(DEROutputStream out)
throws java.io.IOException
- Specified by:
encode
in class DERObject
- Throws:
java.io.IOException
