Interface ZipEncoding
public interface ZipEncoding
An interface for encoders that do a pretty encoding of ZIP
 filenames.
 
There are mostly two implementations, one that uses java.nio
 Charset and one implementation,
 which copes with simple 8 bit charsets, because java-1.4 did not
 support Cp437 in java.nio.
The main reason for defining an own encoding layer comes from
 the problems with String.getBytes, which encodes unknown characters as ASCII
 quotation marks ('?'). Quotation marks are per definition an
 invalid filename on some operating systems  like Windows, which
 leads to ignored ZIP entries.
All implementations should implement this interface in a reentrant way.

Method SummaryModifier and TypeMethodDescriptionbooleanCheck, whether the given string may be losslessly encoded using this encoding.decode(byte[] data) Encode a filename or a comment to a byte array suitable for storing it to a serialized zip entry.

Method Details- 
canEncodeCheck, whether the given string may be losslessly encoded using this encoding.- Parameters:
- name- A filename or ZIP comment.
- Returns:
- Whether the given name may be encoded with out any losses.
 
- 
encodeEncode a filename or a comment to a byte array suitable for storing it to a serialized zip entry.Examples for CP 437 (in pseudo-notation, right hand side is C-style notation): encode("€_for_Dollar.txt") = "%U20AC_for_Dollar.txt" encode("Ölfässer.txt") = "\231lf\204sser.txt"- Parameters:
- name- A filename or ZIP comment.
- Returns:
- A byte buffer with a backing array containing the
         encoded name.  Unmappable characters or malformed
         character sequences are mapped to a sequence of utf-16
         words encoded in the format %Uxxxx. 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.
- Throws:
- IOException- if something goes wrong
 
- 
decode- Parameters:
- data- The byte values to decode.
- Returns:
- The decoded string.
- Throws:
- IOException- if something goes wrong
