Field Summary

static java.nio.charset.Charset	ASCII_CHARSET
static java.lang.String	DEFAULT_CHARACTER_ENCODING
static java.nio.charset.Charset	DEFAULT_CHARSET
static java.nio.charset.Charset	UTF8_CHARSET

Constructor Summary

Charsets()

Method Summary

static void	drainAllCharsets() Removes all the charsets preloaded before.
static java.nio.charset.Charset	lookupCharset(java.lang.String charsetName) Lookup a Charset by name.
static void	preloadAllCharsets() Preloads all JVM available Charsets, which makes charset search faster (for memory cost), especially non-existed charsets, because it lets us avoid pretty expensive Charset.forName(java.lang.String) call.
