- Direct Known Subclasses:
- BERTaggedObject, DERTaggedObject, DLTaggedObject
- public abstract class ASN1TaggedObject
- extends ASN1Primitive
- implements ASN1TaggedObjectParser
ASN.1 TaggedObject - in ASN.1 notation this is any object preceded by
a [n] where n is some number - these are assumed to follow the construction
rules (as with sequences).
Constructor Summary |
ASN1TaggedObject(boolean explicit,
int tagNo,
ASN1Encodable obj)
Create a tagged object with the style given by the value of explicit. |

ASN1TaggedObject
public ASN1TaggedObject(boolean explicit,
int tagNo,
ASN1Encodable 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)
hashCode
public int hashCode()
- Overrides:
hashCode
in class ASN1Primitive
getTagNo
public int getTagNo()
- Return the tag number associated with this object.
- Specified by:
getTagNo
in interface ASN1TaggedObjectParser
- Returns:
- the tag number.
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.
getObject
public ASN1Primitive 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 ASN1Encodable getObjectParser(int tag,
boolean isExplicit)
throws java.io.IOException
- 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
- Following copied from interface:
org.bouncycastle.asn1.ASN1TaggedObjectParser
- Parameters:
tag
- the primitive tag value for the object tagged originally.isExplicit
- true if the tagging was done explicitly.- Returns:
- a parser for the tagged object.
- Throws:
java.io.IOException
- if a parser cannot be constructed.
getLoadedObject
public ASN1Primitive getLoadedObject()
- Description copied from interface:
InMemoryRepresentable
- Get the in-memory representation of the ASN.1 object.
- Specified by:
getLoadedObject
in interface InMemoryRepresentable
- Following copied from interface:
org.bouncycastle.asn1.InMemoryRepresentable
- Returns:
- an ASN1Primitive representing the loaded object.
- Throws:
java.io.IOException
- for bad input data.
toString
public java.lang.String toString()
- Overrides:
toString
in class java.lang.Object
