Member Function Documentation

void add ( TransformBase * ) [inherited]

Adds a prototype object to the list of prototypes.

TransformBase * create ( const std::string & name ) [inherited]

Creates a new object from a prototype named name.

If found, returns a new object by invoking the clone() member function of the prototype. If not found, throws a FactoryException object with the name not found.

TransformBase * createTransform ( const std::string & name )

If the name contains a non-alphanumeric character, then an XYTransform is cnstructed by parsing the two alphanumeric parts of the name as names of UnaryTransform names.

Note that this functions name differs from the other Factory function nams becasue I (pfkeb) couldn't figure out how to override the function and yet be able to call the base class function.

Attention:: Do not try to use the given name first and if it fails catch the exception and parse the name for space. Doing so will break the Java version based on jdk-1.3.1 because of apparent incompatiblities in exception handling between the version of gcc used to compile the Java VM and gcc 2.95.3.
