This implementation is thread safe. author:    Gianluca Brigandi version:    $Id$ Field Summary final protected static  String DEFAULT_ALGORITHM      The default message digest algorithm to use if we cannot use the requested one. protected  String _randomClass      The Java class name of the random number generator class to be used when generating assertion identifiers. Method Summary public  String getAlgorithm()      Return the digest algorithm for the id generator. String the algorithm name (i.e. public  int getAssertionIdLength()      public synchronized  MessageDigest getDigest()      Return the MessageDigest object to be used for calculating assertion identifiers. public  String getEntropy()      Return the entropy increaser value, or compute a semi-useful value if this String has not yet been set. public synchronized  Random getRandom()      Return the random number generator instance we should use for generating assertion identifiers. protected  void getRandomBytes(byte[] bytes)      public  String getRandomClass()      Gets the random number generator class name. public  void setAlgorithm(String algorithm)      Set the message digest algorithm for the id generator. public  void setAssertionIdLength(int idLength)      public  void setEntropy(String entropy)      Set the entropy increaser value. public  void setRandomClass(String randomClass)      Sets the random number generator class name. Field Detail DEFAULT_ALGORITHM final protected static String DEFAULT_ALGORITHM(Code) The default message digest algorithm to use if we cannot use the requested one. _randomClass protected String _randomClass(Code) The Java class name of the random number generator class to be used when generating assertion identifiers. Method Detail getAlgorithm public String getAlgorithm()(Code) Return the digest algorithm for the id generator. String the algorithm name (i.e. MD5). getAssertionIdLength public int getAssertionIdLength()(Code) Gets the assertion id length (in bytes) for Assertions created by this Generator getDigest public synchronized MessageDigest getDigest()(Code) Return the MessageDigest object to be used for calculating assertion identifiers. If none has been created yet, initialize one the first time this method is called. getEntropy public String getEntropy()(Code) Return the entropy increaser value, or compute a semi-useful value if this String has not yet been set. getRandom public synchronized Random getRandom()(Code) Return the random number generator instance we should use for generating assertion identifiers. If there is no such generator currently defined, construct and seed a new one. getRandomBytes protected void getRandomBytes(byte[] bytes)(Code) Generate a byte array containing a assertion identifier getRandomClass public String getRandomClass()(Code) Gets the random number generator class name. setAlgorithm public void setAlgorithm(String algorithm)(Code) Set the message digest algorithm for the id generator. Parameters:   algorithm - The new message digest algorithm setAssertionIdLength public void setAssertionIdLength(int idLength)(Code) Sets the assertion id length (in bytes) for Assertions created by this Generator Parameters:   idLength - The assertion id length setEntropy public void setEntropy(String entropy)(Code) Set the entropy increaser value. Parameters:   entropy - The new entropy increaser value setRandomClass public void setRandomClass(String randomClass)(Code) Sets the random number generator class name.
