Detailed Description

template<typename TValue>
struct itk::VariableLengthVector< TValue >::KeepOldValues

VariableLengthVector Invariability Policy: Always keep old values. This policy, when used from VariableLengthVector::SetSize(), always copies min(newSize,oldSize) previous values from the previous internal buffer to the new one

Precondition

This policy is only meant to be executed in case of reallocation, i.e. oldBuffer and newBuffer are expected to differ (unchecked).

This presumes TValue assignment is a noexcept operation.

newBuffer is not null (pre-conditions imposed by some implementations of std::copy())

[oldBuffer, oldBuffer+oldSize) is a valid range

This behaviour mimics std::vector<>::resize() behaviour. However, it makes to sense from VariableLengthVector::operator=()
