Class w3c.www.dsig.SigBlockExtension 

java.lang.Object
   |
   +----w3c.www.dsig.SigBlockExtension
public class SigBlockExtension
extends Object
DSig SigBlockExtension class.

This class is a representation of the DSig SigBlock as defined in the DSig label specification. A SigBlock consists of some AttribInfo and zero or more signatures.

The class allows to get and set the sigblock's attribinfo, add remove, etc. signature suites, and to verify the signatures contained in the signatures suites.

Variable Index

o EXTENSION_ID
The name of the extension identifier

Constructor Index

o SigBlockExtension()
Create an empty Signature Block

Method Index

o addSigSuite(SignatureSuite)
Add a SigSuite to this SigBlock's list of signatures suite.
o getAttribInfo()
Returns this SigBlock's AttribInfo object.
o getSigSuiteAt(int)
Return the signature at position index in this SigBlock.
o getSigSuites(String)
Get all signature suites with the identifying URL suitename; Returns an array of size 0 if none are found.
o parse(Vector)
parse a UserOptionValue into a SigBlock
o removeAllSigSuites()
Remove all signature suites from the sigblock.
o removeSigSuite(SignatureSuite)
Removes a SigSuite from the SigBlock
o setAttribInfo(AttribInfo)
Sets the SigBlock's AttribInfo to the given object.
o sigSuites()
Return an enumeration of all signature suites in this sigblock.
o size()
Returns the number of SigSuites that are stored in this SigBlock object.
o toString()
Return an S-Expression string representation of this SigBlock extension.
o toVector()
Return an S-Expression Vector representation of this SigBlock extension.
o verify(DSigLabelInterface)
Verify the signature suites in this sigblock according to the user's default policy.
o verify(DSigLabelInterface, String)
Verify if all signatures suites with the identifying URL suitename in this sigblock correctly sign the given label.
o verifyAll(DSigLabelInterface)
Verify if all signatures suites in this sigblock correctly sign the given label.

Variables

o EXTENSION_ID 
 public static final String EXTENSION_ID
The name of the extension identifier

Constructors

o SigBlockExtension 
 public SigBlockExtension()
Create an empty Signature Block

Methods

o verify 
 public Trivalue verify(DSigLabelInterface label)
Verify the signature suites in this sigblock according to the user's default policy. Currently hardcoded to be equivalent to verifyAll(label).

o verifyAll 
 public Trivalue verifyAll(DSigLabelInterface label)
Verify if all signatures suites in this sigblock correctly sign the given label.

o verify 
 public Trivalue verify(DSigLabelInterface label,
                        String suiteName)
Verify if all signatures suites with the identifying URL suitename in this sigblock correctly sign the given label.

o parse 
 public void parse(Vector v) throws DSigException
parse a UserOptionValue into a SigBlock

Throws: DSigException
if the data cannot be parsed correctly.
o getAttribInfo 
 public AttribInfo getAttribInfo()
Returns this SigBlock's AttribInfo object.

o setAttribInfo 
 public void setAttribInfo(AttribInfo ainfo)
Sets the SigBlock's AttribInfo to the given object.

o addSigSuite 
 public void addSigSuite(SignatureSuite suite)
Add a SigSuite to this SigBlock's list of signatures suite.

o removeSigSuite 
 public boolean removeSigSuite(SignatureSuite suite)
Removes a SigSuite from the SigBlock

Returns:
true if the SigSuite was found and removed, false otherwise.
o removeAllSigSuites 
 public void removeAllSigSuites()
Remove all signature suites from the sigblock. Usefull when the label has been modified so that the signatures would be invalid anyway.

o getSigSuites 
 public SignatureSuite[] getSigSuites(String suiteName)
Get all signature suites with the identifying URL suitename; Returns an array of size 0 if none are found.

o sigSuites 
 public Enumeration sigSuites()
Return an enumeration of all signature suites in this sigblock.

o size 
 public int size()
Returns the number of SigSuites that are stored in this SigBlock object.

o getSigSuiteAt 
 public SignatureSuite getSigSuiteAt(int index) throws ArrayIndexOutOfBoundsException
Return the signature at position index in this SigBlock.

Throws: ArrayIndexOutOfBoundsException
if the index is not valid.
o toVector 
 public Vector toVector()
Return an S-Expression Vector representation of this SigBlock extension.

o toString 
 public String toString()
Return an S-Expression string representation of this SigBlock extension.

Overrides:
toString in class Object
