public Inflater() 
{
        this(false);
}

Creates a new decompressor.

 public Inflater(boolean nowrap) 
{
        zsRef = new ZStreamRef(init(nowrap));
}

Creates a new decompressor. If the parameter 'nowrap' is true then the ZLIB header and checksum fields will not be used. This provides compatibility with the compression format used by both GZIP and PKZIP.

Note: When using the 'nowrap' option it is also necessary to provide an extra "dummy" byte as input. This is required by the ZLIB native library in order to support certain optimizations.

Parameters:

nowrap - if true then support GZIP compatible compression

 public  void end() 
{
        synchronized (zsRef) {
            long addr = zsRef.address();
            zsRef.clear();
            if (addr != 0) {
                end(addr);
                buf = null;
            }
        }
}

Closes the decompressor and discards any unprocessed input. This method should be called when the decompressor is no longer being used, but will also be called automatically by the finalize() method. Once this method is called, the behavior of the Inflater object is undefined.

 boolean ended() 
{
        synchronized (zsRef) {
            return zsRef.address() == 0;
        }
}

 protected  void finalize() 
{
        end();
}

Closes the decompressor when garbage is collected.

 public boolean finished() 
{
        synchronized (zsRef) {
            return finished;
        }
}

Returns true if the end of the compressed data stream has been reached.

 public int getAdler() 
{
        synchronized (zsRef) {
            ensureOpen();
            return getAdler(zsRef.address());
        }
}

Returns the ADLER-32 value of the uncompressed data.

 public long getBytesRead() 
{
        synchronized (zsRef) {
            ensureOpen();
            return getBytesRead(zsRef.address());
        }
}

Returns the total number of compressed bytes input so far.

 public long getBytesWritten() 
{
        synchronized (zsRef) {
            ensureOpen();
            return getBytesWritten(zsRef.address());
        }
}

Returns the total number of uncompressed bytes output so far.

 public int getRemaining() 
{
        synchronized (zsRef) {
            return len;
        }
}

Returns the total number of bytes remaining in the input buffer. This can be used to find out what bytes still remain in the input buffer after decompression has finished.

 public int getTotalIn() 
{
        return (int) getBytesRead();
}

Returns the total number of compressed bytes input so far.

Since the number of bytes may be greater than Integer.MAX_VALUE, the #getBytesRead() method is now the preferred means of obtaining this information.

 public int getTotalOut() 
{
        return (int) getBytesWritten();
}

Returns the total number of uncompressed bytes output so far.

Since the number of bytes may be greater than Integer.MAX_VALUE, the #getBytesWritten() method is now the preferred means of obtaining this information.

 public int inflate(byte[] b) throws DataFormatException 
{
        return inflate(b, 0, b.length);
}

Uncompresses bytes into specified buffer. Returns actual number of bytes uncompressed. A return value of 0 indicates that needsInput() or needsDictionary() should be called in order to determine if more input data or a preset dictionary is required. In the latter case, getAdler() can be used to get the Adler-32 value of the dictionary required.

 public int inflate(byte[] b,
    int off,
    int len) throws DataFormatException 
{
        if (b == null) {
            throw new NullPointerException();
        }
        if (off <  0 || len <  0 || off  > b.length - len) {
            throw new ArrayIndexOutOfBoundsException();
        }
        synchronized (zsRef) {
            ensureOpen();
            return inflateBytes(zsRef.address(), b, off, len);
        }
}

Uncompresses bytes into specified buffer. Returns actual number of bytes uncompressed. A return value of 0 indicates that needsInput() or needsDictionary() should be called in order to determine if more input data or a preset dictionary is required. In the latter case, getAdler() can be used to get the Adler-32 value of the dictionary required.

 public boolean needsDictionary() 
{
        synchronized (zsRef) {
            return needDict;
        }
}

Returns true if a preset dictionary is needed for decompression.

 public boolean needsInput() 
{
        synchronized (zsRef) {
            return len < = 0;
        }
}

Returns true if no data remains in the input buffer. This can be used to determine if #setInput should be called in order to provide more input.

 public  void reset() 
{
        synchronized (zsRef) {
            ensureOpen();
            reset(zsRef.address());
            buf = defaultBuf;
            finished = false;
            needDict = false;
            off = len = 0;
        }
}

Resets inflater so that a new set of input data can be processed.

 public  void setDictionary(byte[] b) 
{
        setDictionary(b, 0, b.length);
}

Sets the preset dictionary to the given array of bytes. Should be called when inflate() returns 0 and needsDictionary() returns true indicating that a preset dictionary is required. The method getAdler() can be used to get the Adler-32 value of the dictionary needed.

 public  void setDictionary(byte[] b,
    int off,
    int len) 
{
        if (b == null) {
            throw new NullPointerException();
        }
        if (off <  0 || len <  0 || off  > b.length - len) {
            throw new ArrayIndexOutOfBoundsException();
        }
        synchronized (zsRef) {
            ensureOpen();
            setDictionary(zsRef.address(), b, off, len);
            needDict = false;
        }
}

Sets the preset dictionary to the given array of bytes. Should be called when inflate() returns 0 and needsDictionary() returns true indicating that a preset dictionary is required. The method getAdler() can be used to get the Adler-32 value of the dictionary needed.

 public  void setInput(byte[] b) 
{
        setInput(b, 0, b.length);
}

Sets input data for decompression. Should be called whenever needsInput() returns true indicating that more input data is required.

 public  void setInput(byte[] b,
    int off,
    int len) 
{
        if (b == null) {
            throw new NullPointerException();
        }
        if (off <  0 || len <  0 || off  > b.length - len) {
            throw new ArrayIndexOutOfBoundsException();
        }
        synchronized (zsRef) {
            this.buf = b;
            this.off = off;
            this.len = len;
        }
}

Sets input data for decompression. Should be called whenever needsInput() returns true indicating that more input data is required.
