CHOICE.Template
public CHOICE.Template()
- Creates an empty CHOICE template
Method Detail |

addElement
public void addElement(ASN1Template template)
- Adds a new sub-template to this CHOICE template with no implicit tag.
addElement
public void addElement(Tag implicitTag, ASN1Template template)
- Adds a new sub-template to this CHOICE template with an implicit tag.
size
public int size()
- Returns the number of elements in this CHOICE template.
elementAt
public ASN1Template elementAt(int index)
- Retrieves the element at the specified index.
implicitTagAt
public Tag implicitTagAt(int index)
- Retrieves the implicit tag of the element at the specified index.
Returns null if there is no implicit tag for this element.
removeAllElements
public void removeAllElements()
- Empties this CHOICE template.
removeElementAt
public void removeElementAt(int index)
- Removes the element at the specified index.
tagMatch
public boolean tagMatch(Tag t)
- Determines whether the given tag will satisfy this template.
For a CHOICE, this is true if the tag satisfies any sub-template.
- Specified by:
tagMatch
in interfaceASN1Template
decode
public ASN1Value decode(java.io.InputStream istream) throws java.io.IOException, InvalidBERException
- Description copied from interface:
ASN1Template
- Decodes an ASN1Value from the InputStream without an implicit tag.
- Specified by:
decode
in interfaceASN1Template
- Parameters:
istream
- Must support marking (markSupported() == true). For example, ByteArrayInputStream and BufferedInputStream support marking, but FileInputStream does not. If your source does not support marking, you can wrap it in a BufferedInputStream.- Throws:
java.io.IOException
InvalidBERException
decode
public ASN1Value decode(Tag implicitTag, java.io.InputStream istream) throws java.io.IOException, InvalidBERException
- Decodes a CHOICE.
- Specified by:
decode
in interfaceASN1Template
- Parameters:
implicitTag
- This parameter is ignored. A choice cannot have an implicit tag.istream
- Must support marking (markSupported() == true). For example, ByteArrayInputStream and BufferedInputStream support marking, but FileInputStream does not. If your source does not support marking, you can wrap it in a BufferedInputStream.- Throws:
java.io.IOException
InvalidBERException
