Interface TimeStampDigestInput

public interface TimeStampDigestInput

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.

Method Summary

Modifier and Type	Method	Description
void	addNode(Node n)	Adds a Node to the input.
void	addReference(org.apache.xml.security.signature.Reference r)	Adds a Reference to the input.
byte[]	getBytes()	Gets the octet-stream corresponding to the actual state of the input.

Method Details

addReference

void addReference(org.apache.xml.security.signature.Reference r)
           throws CannotAddDataToDigestInputException

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

addNode

void addNode(Node n)
      throws CannotAddDataToDigestInputException

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

getBytes

byte[] getBytes()

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

Returns:

the octet-stream (always a new instance)
