- Does not derives from Object anymore, now it derives from DataObject.
- typedef for InstanceIdentifier was replaced from unsigned long to std::vector<MeasurementVectorType>::size_type
- Size() method now returns InstanceIdentifier type, before it returned unsigned int, which was inconsistent with the declaration of InstanceIdentifier as unsigned long. The return type of Size() must be the same use for Id of the elements, since it may reach the same maximum number.
- Removing unnecessary const in identifiers
- GetMeasurementVector( const InstanceItentifier & id ) is now GetMeasurementVector( InstanceItentifier id )
- GetFrequency( const InstanceItentifier & id ) is now GetFrequency( InstanceItentifier id )
- SetMeasurementVectorSize( const MeasurementVectorSizeType s ) is now SetMeasurementVectorSize( MeasurementVectorSizeType s )
|
- const-correctness is now enforced.
- It now derives from DataObject
|
| Subsample |
Refactored |
- The concept of Indices and InstanceIdentifiers was fixed. InstanceIdentifiers were previously referring to the original Sample, they are now referring to the current Subsample set of measurement vectors.
- It now derives from its template argument. Before, it was deriving from an explicit itk::Statistics::Sample<> whose template argument MeasurementVector was taken as a trait from the Subsample template argument. The current derivation is more consistent with the notion that the Subsample should behave as the sample from which the instances are taken.
- FrequencyType GetFrequencyByIndex(int index) const : was removed. This method becomes obsolete when the inconsistencies between index and identifier are removed.
- InstanceIdentifier GetInstanceIdentifier(int index) const; was removed. This method becomes obsolete when the inconsistencies between index and identifier are removed.
- Iterators
- Common
- GetInstanceIdentifier() now returns the integer distance to the Begin() element. Before it used to return the index of the instance in the real sample.
- Iterator& operator+(int n) and Iterator& operator-(int n) were removed. The methods were not used, and they were not consistent with other containers. They were also unsafe, given that with Begin() and End() there is no way to verify if an iterator has moved before Begin() or after End() (unless we rely on being aware of the underlying pointer implementation of the Iterators, which would be a violation of the class encapsulation).
- Constructor ConstIterator(typename InstanceIdentifierHolder::const_iterator iter, const Self* classSample) was made protected, since this constructor must only be called by the Sample owner class.
- ConstIterator
- removing Friendship to the Iterator
- non-const Iterator
- removing Friendship to the ConstIterator
|
- The basic principle followed now in the design of the Subsample class is that the subsample should behave as a sample. That is, a user should be able to use a Subsample class in any algorithm that is expecting a Sample.
- AddInstance( InsitanceIdentifier Id )
- Now throws an exception if the Id is larger than the Size of the Sample.
- Now it calls Modified()
- Iterators
- Now the non-const Iterator derives from the ConstIterator
- Methods declared protected and purposely not implemented
- Default constructor: This was a safety risk since it contained uninitialized variables
- The following method are in this category to enforce const correctness. All of them could have offered ways of removing constness without warning
- Iterator(const Self * sample);
- Iterator(typename InstanceIdentifierHolder::const_iterator iter, const Self* classSample);
- Iterator(const ConstIterator & it);
- ConstIterator& operator=(const ConstIterator& it);

| ListSampleBase |
Deprecated. The class was unecessary, it was providing only a Search() method that should in fact be provided by a process class, not a data container.
|
- If you were deriving a class from the itk::Statistics::ListSampleBase, you should now derive directly from the itk::Statistics::Sample class.
- If you were using the Search() method you can get that functionality now from the itkStatisticsAlgorithm Search() algorithm.
