MembershipSampleGenerator generates a MembershipSample object using a class mask sample.
You can see it as a filter that takes two samples as input and generates a MembershipSample. There are two class template arguments first one is the type of basic sample that has measurement vectors in it, and the second one is the type of sample that its measurement vectors has only one component - class label. What it does is that it merges measurement vectors and class labels in a single MembershipSample object.
To get the MembershipSample object you should plug in the input sample and the class mask sample using SetInput and SetClassMask methods respectively.
NOTE: This generator expects the class labels in the class mask sample to be integer value where the value starts 0 and increases without any missing value between 0 to the last class label value.

unsigned long itk::Object::AddObserver | ( | const EventObject & | event, | |
Command * | ||||
) | [inherited] |
Allow people to add/remove/invoke observers (callbacks) to any ITK object. This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and an itk::Command to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command. The memory for the Command becomes the responsibility of this object, so don't pass the same instance of a command to two different objects

static void itk::LightObject::BreakOnError | ( | ) | [static, inherited] |
This method is called when itkExceptionMacro executes. It allows the debugger to break on error.
virtual LightObject::Pointer itk::Object::CreateAnother | ( | ) | const [virtual, inherited] |
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.

virtual void itk::Object::DebugOn | ( | ) | const [virtual, inherited] |
Turn debugging output on.
virtual void itk::LightObject::Delete | ( | ) | [virtual, inherited] |
Delete an itk 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.
