From commit ENH: Make index type of VectorContainer SizeValueType by default · InsightSoftwareConsortium/ITK@4b5e5be · GitHub (merged to the “master” branch for ITK 6.0), it is no longer necessary to explicitly specify the index type (“ElementIdentifier”) of an itk::VectorContainer. The index type is now itk::SizeValueType by default. So for example, in user code, itk::VectorContainer<itk::SizeValueType, float> may be replaced with itk::VectorContainer<float>.
With the following pull request, I’m proposing to remove those explicit template arguments from a few VectorContainer use cases in the ITK source tree itself. Please have a look:
