Description

The list of methods to do GZip are organized into topic(s).

Method

byte[] gzip(final T o)
passed object convert to gziped byte array.

if (o == null) {
 return null;
try (final ByteArrayOutputStream baos = new ByteArrayOutputStream();
 final GZIPOutputStream gzip = new GZIPOutputStream(baos);) {
 gzip.write(MAPPER.writeValueAsBytes(o));
 ;
 gzip.close();
...

byte[] gzip(String s)
gzip

ByteArrayOutputStream bos = new ByteArrayOutputStream();
GZIPOutputStream gzip = new GZIPOutputStream(bos);
OutputStreamWriter osw = new OutputStreamWriter(gzip, StandardCharsets.UTF_8);
osw.write(s);
osw.close();
return bos.toByteArray();

String gzip(String str)
gzip

if (null == str || str.length() < 1) {
 return str;
ByteArrayOutputStream out = new ByteArrayOutputStream();
try (GZIPOutputStream gzip = new GZIPOutputStream(out)) {
 gzip.write(str.getBytes());
return out.toString(CHARSET_ZIP.name());
...

String gzipDecompress(byte[] compressed)
gzip Decompress

byte[] bytes = gzipDecompressBytes(compressed);
return new String(bytes, StandardCharsets.UTF_8);

BufferedReader gzipFileReader(String file)
gzip File Reader

return new BufferedReader(new InputStreamReader(new GZIPInputStream(new FileInputStream(file)), UTF8));

BufferedReader gzipReader(final InputStream inputStream)
gzip Reader

return reader(new GZIPInputStream(inputStream));

byte[] gzipString(String src, byte default_value[])
gzip String

if (src == null)
 return default_value;
return gzip(src.getBytes(utf8), default_value);
