Create instances of classes using an object factory.
ObjectFactoryBase is used to create igtl objects. The base class ObjectFactoryBase contains a static method CreateInstance() that is used to create igtl objects from the list of registerd ObjectFactoryBase sub-classes. The first time CreateInstance() is called, all dll's or shared libraries in the environment variable IGTL_AUTOLOAD_PATH are loaded into the current process. The C function igtlLoad is called on each dll. igtlLoad should return an instance of the factory sub-class implemented in the shared library. IGTL_AUTOLOAD_PATH is an environment variable containing a colon separated (semi-colon on win32) list of paths.
This can be use to overide the creation of any object in IGTL.

This method is called when igtlExceptionMacro executes. It allows the debugger to break on error.
|
static |
Create and return all possible instances of the named igtl object. Each loaded ObjectFactoryBase will be asked in the order the factory was in the IGTL_AUTOLOAD_PATH. All created objects will be returned in the list.
|
virtualinherited |
Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.
Reimplemented from igtl::LightObject.
|
static |
Create and return an instance of the named igtl object. Each loaded ObjectFactoryBase will be asked in the order the factory was in the IGTL_AUTOLOAD_PATH. After the first factory returns the object no other factories are asked.
Referenced by igtl::ObjectFactory< T >::Create().
|
protectedvirtual |
This method is provided by sub-classes of ObjectFactoryBase. It should create the named igtl object or return 0 if that object is not supported by the factory implementation.
Delete an igtl object. This method should always be used to delete an object when the new operator was used to create it. Using the C delete method will not work with reference counting.
Set all enable flags for the given class to 0. This will mean that the factory will stop producing class with the given name.
|
virtual |
Return a list of descriptions for class overrides.
|
virtual |
Return a list of classes that this factory overrides.
|
virtual |
Return a list of the names of classes that override classes.
|

Get the value of the debug flag.
Return a descriptive string describing the factory.
|
virtual |
Get the Enable flag for the specific override of className.
Return a list of enable flags.
All sub-classes of ObjectFactoryBase should must return the version of IGTL they were built with. This should be implemented with the macro IGTL_SOURCE_VERSION and NOT a call to Version::GetIGTLSourceVersion. As the version needs to be compiled into the file as a string constant. This is critical to determine possible incompatible dynamic factory loads.
This returns the path to a dynamically loaded factory.
Return the name of this class as a string. Used by the object factory (implemented in New()) to instantiate objects of a named type. Also used for debugging and other output information.

Return the list of all registered factories. This is NOT a copy, do not remove items from this list!
Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Number of uses of this object by other objects.
Return this objects modified time.
Update the modification time for this object. Many filters rely on the modification time to determine if they need to recompute their data.
Increase the reference count (mark as used by another object).
Reimplemented from igtl::LightObject.

static |
Register a factory so it can be used to create igtl objects.
|
protected |
Register object creation information with the factory.
Re-check the IGTL_AUTOLOAD_PATH for new factory libraries. This calls UnRegisterAll before re-loading.
Set the value of the debug flag. A non-zero value turns debugging on.
|
virtual |
Set the Enable flag for the specific override of className.
This is a global flag that controls whether any debug, warning or error messages are displayed.
Sets the reference count (use with care)

Decrease the reference count (release by another object).
