-//  UVector64 is a class implementing a vector of 64 bit integers.
-//            It is similar to UVector32, but holds int64_t values rather than int32_t.
-//            Most of the code is unchanged from UVector.

-/**
- * <p>Ultralightweight C++ implementation of an <tt>int64_t</tt> vector
- * that has a subset of methods from UVector32
- *
- * <p>This is a very simple implementation, written to satisfy an
- * immediate porting need.  As such, it is not completely fleshed out,
- * and it aims for simplicity and conformity.  Nonetheless, it serves
- * its purpose (porting code from java that uses java.util.Vector)
- * well, and it could be easily made into a more robust vector class.
- *
- * <p><b>Design notes</b>
- *
- * <p>There is index bounds checking, but little is done about it.  If
- * indices are out of bounds, either nothing happens, or zero is
- * returned.  We <em>do</em> avoid indexing off into the weeds.
- *
- * <p>There is detection of out of memory, but the handling is very
- * coarse-grained -- similar to UnicodeString's protocol, but even
- * coarser.  The class contains <em>one static flag</em> that is set
- * when any call to <tt>new</tt> returns zero.  This allows the caller
- * to use several vectors and make just one check at the end to see if
- * a memory failure occurred.  This is more efficient than making a
- * check after each call on each vector when doing many operations on
- * multiple vectors.  The single static flag works best when memory
- * failures are infrequent, and when recovery options are limited or
- * nonexistent.
- *
- * <p><b>To do</b>
- *
- * <p>Improve the handling of index out of bounds errors.
