Example 6 with ArrayDecoder

use of sun.nio.cs.ArrayDecoder in project Bytecoder by mirkosertic.

the class ZipCoder method toString.

String toString(byte[] ba, int off, int length) {
    CharsetDecoder cd = decoder().reset();
    int len = (int) (length * cd.maxCharsPerByte());
    char[] ca = new char[len];
    if (len == 0)
        return new String(ca);
    // REPORT mode.
    if (isUTF8 && cd instanceof ArrayDecoder) {
        int clen = ((ArrayDecoder) cd).decode(ba, off, length, ca);
        if (// malformed
        clen == -1)
            throw new IllegalArgumentException("MALFORMED");
        return new String(ca, 0, clen);
    }
    ByteBuffer bb = ByteBuffer.wrap(ba, off, length);
    CharBuffer cb = CharBuffer.wrap(ca);
    CoderResult cr = cd.decode(bb, cb, true);
