java.lang.Objectorg.apache.commons.compress.archivers.zip.NioZipEncoding
class NioZipEncoding
A ZipEncoding, which uses a java.nio Charset
to encode names.
This implementation works for all cases under java-1.5 or later. However, in java-1.4, some charsets don't have a java.nio implementation, most notably the default ZIP encoding Cp437.
The methods of this class are reentrant.

Examples for CP 437 (in pseudo-notation, right hand side is C-style notation):
encode("?_for_Dollar.txt") = "%U20AC_for_Dollar.txt" encode("?lf?sser.txt") = "\231lf\204sser.txt"

- A filename or ZIP comment.

. It is
assumed, that the byte buffer is positioned at the
beginning of the encoded result, the byte buffer has a
backing array and the limit of the byte buffer points
to the end of the encoded result.ZipEncoding.encode(java.lang.String)

- The byte values to decode.
