public class CharBuffer

extends Object

implements Sequence

The implementation store elements in a contiguous linear memory space so that index-based access is very quick. When an CharBuffer's originally allocated memory space is exceeded, its elements are copied into a new memory space that is large enough to accomodate everything.

If an insertion causes reallocation, all iterators and references are invalidated; otherwise, only the iterators and references after the insertion point are invalidated.

A remove invalidates all of the iterators and references after the point of the remove.
