Class CHOICE
java.lang.Object org.mozilla.jss.asn1.CHOICE
- All Implemented Interfaces:
- ASN1Value
public class CHOICE
- extends java.lang.Object
- implements ASN1Value
- extends java.lang.Object
Objects of this class are generated by CHOICE.Template.decode(). It is not necessary to use them to encode a CHOICE. Since the encoding of a CHOICE is simply the encoding of the chosen element, it is easier to just write out the chosen element.

CHOICE(ASN1Value val)

CHOICE
public CHOICE(Tag implicitTag, ASN1Value val)
- Create a CHOICE whose chosen element has an implicit tag.
CHOICE
public CHOICE(ASN1Value val)
- Create a CHOICE whose chosen element has no implicit tag.
Method Detail |
---|
getTag
public Tag getTag()
- Returns the tag that the chosen element is encoded with, which is
either the underlying tag of the element or an implicit tag.
getValue
public ASN1Value getValue()
- Returns the chosen value.
getTemplate
public static CHOICE.Template getTemplate()
encode
public void encode(java.io.OutputStream ostream) throws java.io.IOException
- Encodes this CHOICE. This merely consists of encoding the chosen
element with an implicit tag, if one was given in the constructor,
or with its own underlying tag.
- Throws:
java.io.IOException
encode
public void encode(Tag implicitTag, java.io.OutputStream ostream) throws java.io.IOException
- Encodes this CHOICE. This merely consists of encoding the chosen
element with an implicit tag, if one was given in the constructor,
or with its own underlying tag.
- Parameters:
implicitTag
- This value is ignored. The tag of a CHOICE is merely the tag of the chosen element of the CHOICE. A CHOICE cannot itself have an implicit tag.- Throws:
java.io.IOException
