UTF7StyleCharset

• java.lang.Object
  • java.nio.charset.Charset

Fields Summary
private static final List	CONTAINED
final boolean	strict
Base64Util	base64

Constructors Summary

protected UTF7StyleCharset(String canonicalName, String[] aliases, String alphabet, boolean strict) Besides the name and aliases, two additional parameters are required. First the base 64 alphabet used; in modified UTF-7 a slightly different alphabet is used. Additionally, it should be specified if encoders and decoders should be strict about the interpretation of malformed encoded sequences. This is used since modified UTF-7 specifically disallows some constructs which are allowed (or not specifically disallowed) in UTF-7 (RFC 2152). param canonicalName The name as defined in java.nio.charset.Charset param aliases The aliases as defined in java.nio.charset.Charset param alphabet The base 64 alphabet used param strict True if strict handling of sequences is requested super(canonicalName, aliases); this.base64 = new Base64Util(alphabet); this.strict = strict;

Methods Summary
abstract boolean	canEncodeDirectly(char ch) Tells if a character can be encoded using simple (US-ASCII) encoding or requires base 64 encoding. param ch The character return True if the character can be encoded directly, false otherwise
public boolean	contains(java.nio.charset.Charset cs) return CONTAINED.contains(cs.name());
public java.nio.charset.CharsetDecoder	newDecoder() return new UTF7StyleCharsetDecoder(this, base64, strict);
public java.nio.charset.CharsetEncoder	newEncoder() return new UTF7StyleCharsetEncoder(this, base64, strict);
abstract byte	shift() Returns character used to switch to base 64 encoding. return The shift character
abstract byte	unshift() Returns character used to switch from base 64 encoding to simple encoding. return The unshift character
