### AbstractAssociator

    public AbstractAssociator()

Method Detail

### forName

    public static Associator forName(java.lang.String associatorName,
                                     java.lang.String[] options)
                              throws java.lang.Exception

  Creates a new instance of a associator given it's class name and (optional) arguments to pass to it's setOptions method. If the associator implements OptionHandler and the options parameter is non-null, the associator will have it's options set.

  Parameters:
    `associatorName` - the fully qualified class name of the associator
    `options` - an array of options suitable for passing to setOptions. May be null.
  Returns:
    the newly created associator, ready for use.
  Throws:
    `java.lang.Exception` - if the associator name is invalid, or the options supplied are not acceptable to the associator

### makeCopy

    public static Associator makeCopy(Associator model)
                               throws java.lang.Exception

  Creates a deep copy of the given associator using serialization.

  Parameters:
    `model` - the associator to copy
  Returns:
    a deep copy of the associator
  Throws:
    `java.lang.Exception` - if an error occurs

### makeCopies

    public static Associator[] makeCopies(Associator model,
                                          int num)
                                   throws java.lang.Exception

  Creates copies of the current associator. Note that this method now uses Serialization to perform a deep copy, so the Associator object must be fully Serializable. Any currently built model will now be copied as well.

  Parameters:
    `model` - an example associator to copy
    `num` - the number of associators copies to create.
  Returns:
    an array of associators.
  Throws:
    `java.lang.Exception` - if an error occurs

### getCapabilities

    public Capabilities getCapabilities()

  Returns the Capabilities of this associator. Maximally permissive capabilities are allowed by default. Derived associators should override this method and first disable all capabilities and then enable just those capabilities that make sense for the scheme.

  Specified by:
    `getCapabilities` in interface `Associator`
  Specified by:
    `getCapabilities` in interface `CapabilitiesHandler`
  Returns:
    the capabilities of this object
  See Also:
    `Capabilities`

### getRevision

    public java.lang.String getRevision()

  Returns the revision string.

  Specified by:
    `getRevision` in interface `RevisionHandler`
  Returns:
    the revision
