TimeStampDigestInput

xades4j.utils.TimeStampDigestInput

Class Overview

Builder of inputs for time-stamps. The digests for time-stamps are usually calculated over a concatenations of byte-streams, resulting from nodes and/or References (processed or not), with the proper canonicalization if needed. This interface provides methods to build a sequential input by adding DOM Nodes or References.

Summary

Public Methods
abstract void addNode(Node n)
Adds a Node to the input.
abstract void addReference(Reference r)
Adds a Reference to the input.
abstract byte[] getBytes()
Gets the octet-stream corresponding to the actual state of the input.

Public Methods

public abstract void addNode (Node n)

Adds a Node to the input. The node is canonicalized.

Parameters
n the node to be added
Throws
CannotAddDataToDigestInputException if there is an error adding the node
NullPointerException if n is null

public abstract void addReference (Reference r)

Adds a Reference to the input. It is processed and the result is canonicalized if it is a node-set.

Parameters
r the reference to be added
Throws
CannotAddDataToDigestInputException if there is an error adding the reference
NullPointerException if r is null

public abstract byte[] getBytes ()

Gets the octet-stream corresponding to the actual state of the input.

Returns
  • the octet-stream (always a new instance)
