class TMeshAttributeArrayBase

Remarks

This defines the container used to hold mesh element attributes of a particular name and index. It is a simple TArray, so that all attributes are packed contiguously for each element ID.

that the container may grow arbitrarily as new elements are inserted, but it will never be shrunk as elements are removed. The only operations that will shrink the container are Initialize() and Remap().
