forName
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 associatoroptions
- an array of options suitable for passing to setOptions. May be null.- Returns:
- the newly created associator, ready for use.
- Throws:
Exception
- if the associator name is invalid, or the options supplied are not acceptable to the associator
-
makeCopy
Creates a deep copy of the given associator using serialization.- Parameters:
model
- the associator to copy- Returns:
- a deep copy of the associator
- Throws:
Exception
- if an error occurs
-
makeCopies
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 copynum
- the number of associators copies to create.- Returns:
- an array of associators.
- Throws:
Exception
- if an error occurs
-
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:

- Specified by:

in interfaceCapabilitiesHandler
- Returns:
- the capabilities of this object

getRevision
Returns the revision string.- Specified by:
getRevision
in interfaceRevisionHandler
- Returns:
- the revision
