示例1: encode
import sun.nio.cs.ArrayEncoder; //导入依赖的package包/类
byte[] encode(char[] ca, int off, int len) {
int en = scale(len, ce.maxBytesPerChar());
byte[] ba = new byte[en];
if (len == 0)
return ba;
if (ce instanceof ArrayEncoder) {
int blen = ((ArrayEncoder)ce).encode(ca, off, len, ba);
return safeTrim(ba, blen, cs, isTrusted);
} else {
ce.reset();
ByteBuffer bb = ByteBuffer.wrap(ba);
CharBuffer cb = CharBuffer.wrap(ca, off, len);
try {
CoderResult cr = ce.encode(cb, bb, true);
if (!cr.isUnderflow())
cr.throwException();
cr = ce.flush(bb);
if (!cr.isUnderflow())
cr.throwException();
} catch (CharacterCodingException x) {
// Substitution is always enabled,
// so this shouldn't happen
throw new Error(x);
}
return safeTrim(ba, bb.position(), cs, isTrusted);
}
}
示例2: getBytes
import sun.nio.cs.ArrayEncoder; //导入依赖的package包/类
byte[] getBytes(String s) {
CharsetEncoder ce = encoder().reset();
char[] ca = s.toCharArray();
int len = (int)(ca.length * ce.maxBytesPerChar());
byte[] ba = new byte[len];
if (len == 0)
return ba;
// UTF-8 only for now. Other ArrayDeocder only handles
// CodingErrorAction.REPLACE mode.
if (isUTF8 && ce instanceof ArrayEncoder) {
int blen = ((ArrayEncoder)ce).encode(ca, 0, ca.length, ba);
if (blen == -1) // malformed
throw new IllegalArgumentException("MALFORMED");
return Arrays.copyOf(ba, blen);
}
ByteBuffer bb = ByteBuffer.wrap(ba);
CharBuffer cb = CharBuffer.wrap(ca);
CoderResult cr = ce.encode(cb, bb, true);
if (!cr.isUnderflow())
throw new IllegalArgumentException(cr.toString());
cr = ce.flush(bb);
if (!cr.isUnderflow())
throw new IllegalArgumentException(cr.toString());
if (bb.position() == ba.length) // defensive copy?
return ba;
else
return Arrays.copyOf(ba, bb.position());
}
示例3: StringEncoder
import sun.nio.cs.ArrayEncoder; //导入依赖的package包/类
private StringEncoder(Charset cs, String rcn) {
this.requestedCharsetName = rcn;
this.cs = cs;
this.ce = cs.newEncoder()
.onMalformedInput(CodingErrorAction.REPLACE)
.onUnmappableCharacter(CodingErrorAction.REPLACE);
this.isTrusted = (cs.getClass().getClassLoader0() == null);
this.isASCIICompatible = (ce instanceof ArrayEncoder) &&
((ArrayEncoder)ce).isASCIICompatible();
}
