getZipEncoding
public static ZipEncoding getZipEncoding(java.lang.String name)
Instantiates a zip encoding. An NIO based character set encoder/decoder will be returned. As a special case, if the character set is UTF-8, the nio encoder will be configured replace malformed and unmappable characters with '?'. This matches existing behavior from the older fallback encoder.If the requested characer set cannot be found, the platform default will be used instead.
- Parameters:
name
- The name of the zip encoding. Specifynull
for the platform's default encoding.- Returns:
- A zip encoding for the given encoding name.
-
isUTF8
static boolean isUTF8(java.lang.String charsetName)
Returns whether a given encoding is UTF-8. If the given name is null, then check the platform's default encoding.- Parameters:
charsetName
- If the given name is null, then check the platform's default encoding.

growBufferBy
static java.nio.ByteBuffer growBufferBy(java.nio.ByteBuffer buffer, int increment)
