Usage

From source file:divconq.ctp.stream.UngzipStream.java

@Override
public void close() {
    Inflater inf = this.inflater;

    if (inf != null)
        inf.end();

    this.inflater = null;

    ByteBuf rem = this.remnant;

    if (rem != null) {
        rem.release();// w  w w . ja va  2 s.  co  m

        this.remnant = null;
    }

    // not truly thread safe, consider
    for (ByteBuf bb : this.outlist)
        bb.release();

    this.outlist.clear();
