Constructors

o GenericFactory 
 public GenericFactory(String structureToCreate)
Class constructor. It sets up the factory to create instances of the object defined by structureTocreate.

Parameters:
stringToCreate - the fully qualified class name of the class that this factory should create.

Methods

o parser 
 public final TesterStringParser parser()
Gets the parser.

Returns:
the parser
o setParser 
 public void setParser(TesterStringParser pars)
Sets the parser

Parameters:
pars - The new Parser
o create 
 public Object create() throws InstantiationException
Returns an instance of the class this GenericFactory is creating. Requires that the specified class have a zero argument constructor.

Returns:
an instance of the class specified when the factory was created.
Throws: InstantiationException
if there was a problem creating the class.
o create 
 public Object create(String string) throws InstantiationException
Creates an instance of the class this GenericFactory is creating. Uses the string format defined in TesterStringParser to parse the parameters, except that the $ tags are not understood.

Parameters:
string - The parameters, in the format specified by TesterStringParser, to pass to the constructor.
Throws: InstantiationException
if there was a problem creating the class.
o findConstructor 
 public Constructor findConstructor(Class clazz,
                                    Class params[]) throws InstantiationException
Finds the Constructor of the class that should be used to create the object.

Parameters:
clazz - the class to create an instance of.
params - an array of Class objects that store the parameters to use.
Throws: InstantiationException
if the constructor could not be found
o reqClass 
 public final Class reqClass()
Gets the class that this factory creates.

Returns:
the Class this factory creates.
o clear 
 public final void clear()
Deletes the names for structures and locations that were stored, and prepares the factory for another call to generate.

o addStructureName 
 public final void addStructureName(String name)
Adds a names to the list of names for the structures being produced in this call to generate.

Parameters:
name - the name of the structure to append to the list.
o addLocationName 
 public final void addLocationName(String name)
Adds a names to the list of names for the locations being produced in this call to generate.

Parameters:
name - the name of the location to append to the list.
o addStructure 
 public final void addStructure(Object structure)
Adds a structure to the list of structures that were created in this call to generate.

Parameters:
structure - the structure that was created.
o addLocation 
 public final void addLocation(Object location)
Adds a location to the list of location that were created in this call to generate.

Parameters:
location - the location that was created.
o testStructure 
 public TestStructure testStructure()
Returns a TestStructure that contains all the information that was stored during this call to generate.

Returns:
a TestStructure that is suitable for use with a subclass of GenericTester.
