Thanks. It would need to be specified so that it's clear that the method is not a "hook" to expand the capacity, it's simply a connivance method for subclasses override the existing methods or adding new write methods that are not based on the write methods in the superclass.

> What would you think about renaming the method to `setMinCapacity` in order to reduce conflict risk? Roger's point about reduced visibility conflicts is a good one, given the established use of the `ensureCapacity` name.

I think it would be useful some static analysis to get a sense for how many libraries extend BAOS and have their own ensureCapacity method.
