Class StaticKeyInfoGenerator

java.lang.Object
  org.opensaml.xml.security.keyinfo.StaticKeyInfoGenerator

All Implemented Interfaces:

KeyInfoGenerator

public class StaticKeyInfoGenerator
extends Object
implements KeyInfoGenerator

Implementation of KeyInfoGenerator which always returns static KeyInfo data. Note that the argument to generate(Credential) is not used in generating the new KeyInfo, and so may be null. If the original KeyInfo that was passed to this instance is already the child of some other XMLObject at the time generate(Credential) is called, then a newly constructed KeyInfo object will be returned that contains the same data as the original. Otherwise, the original KeyInfo instance is returned directly.

Field Summary

private KeyInfo	keyInfo The KeyInfo object held by this generator instance.
private Marshaller	keyInfoMarshaller Marshaller used in cloning operation.
private Unmarshaller	keyInfoUnmarshaller Unmarshaller used in cloning operation.

Constructor Summary

StaticKeyInfoGenerator(KeyInfo newKeyInfo)
Constructor.

Method Summary

private KeyInfo	clone(KeyInfo origKeyInfo) Clone a KeyInfo and return the new object.
KeyInfo	generate(Credential credential) Generate a new KeyInfo object based on keying material and other information within a credential.
KeyInfo	getKeyInfo() Get the static KeyInfo object held by this generator.
private Marshaller	getMarshaller() Get a KeyInfo marshaller.
private Unmarshaller	getUnmarshaller() Get a KeyInfo unmarshaller.
void	setKeyInfo(KeyInfo newKeyInfo) Set the static KeyInfo object held by this generator.
