Class SET
java.lang.Object org.mozilla.jss.asn1.SET
- All Implemented Interfaces:
- ASN1Value
- Direct Known Subclasses:
- SEQUENCE
public class SET
- extends java.lang.Object
- implements ASN1Value
- extends java.lang.Object
An ASN.1 SET, which is an unordered collection of ASN.1 values. It has an interface like a Java Vector, but the ordering is arbitrary. Null entries may be added; they will be skipped when encoding.

getTag
public Tag getTag()
- Description copied from interface:
ASN1Value
- Returns the base tag for this type, not counting any tags
that may be imposed on it by its context.
addElement
public void addElement(ASN1Value v)
- Adds an element to this SET.
addElement
public void addElement(Tag implicitTag, ASN1Value v)
- Adds an element to this SET with the given implicit tag. For example,
if the ASN.1 were:
MyType ::= SET { item [0] IMPLICIT INTEGER, ... }
then the "item" element could be added (with a sample value of 45) to the SET with:myTypeInstance.addElement( new Tag(0), new INTEGER(45) );
insertElementAt
public void insertElementAt(ASN1Value v, int index)
- Inserts an element at the given index.
insertElementAt
public void insertElementAt(Tag implicitTag, ASN1Value v, int index)
- Inserts an element with the given implicit tag at the given index.
elementAt
public ASN1Value elementAt(int index)
- Returns the element at the given index in the SET.
tagAt
public Tag tagAt(int index)
- Returns the tag of the element at the given index. If the element
has an implicit tag, that is returned. Otherwise, the tag of the
underlying type is returned.
elementWithTag
public ASN1Value elementWithTag(Tag tag)
- Returns the element with the given Tag, or null if no element exists
with the given tag.
size
public int size()
- Returns the number of elements in this SET.
removeAllElements
public void removeAllElements()
- Removes all elements from this SET.
removeElementAt
public void removeElementAt(int index)
- Removes the element from the specified index.
encode
public void encode(java.io.OutputStream ostream) throws java.io.IOException
- Writes the DER encoding to the given output stream.
- Throws:
java.io.IOException
encode
public void encode(Tag implicitTag, java.io.OutputStream ostream) throws java.io.IOException
- Writes the DER encoding to the given output stream,
using the given implicit tag. To satisfy DER encoding rules,
the elements will be re-ordered either by tag or lexicographically.
- Throws:
java.io.IOException
BERencode
public void BERencode(Tag implicitTag, java.io.OutputStream ostream) throws java.io.IOException
- Encodes this SET without re-ordering it. This may violate
DER, but it is within BER.
- Throws:
java.io.IOException
main
public static void main(java.lang.String[] args)
