Constructor Detail

• GZIPInputStream

  public GZIPInputStream​(InputStream in,                       int size)                throwsIOException

  Creates a new input stream with the specified buffer size.

  Parameters:

  in - the input stream

  size - the input buffer size

  Throws:

  ZipException - if a GZIP format error has occurred or the compression method used is unsupported

  IOException - if an I/O error has occurred

  IllegalArgumentException - ifsize <= 0

• GZIPInputStream

  public GZIPInputStream​(InputStream in)                throwsIOException

  Creates a new input stream with a default buffer size.

  Parameters:

  in - the input stream

  Throws:

  ZipException - if a GZIP format error has occurred or the compression method used is unsupported

  IOException - if an I/O error has occurred

Method Detail

• read

  public int read​(byte[] buf,                int off,                int len)         throwsIOException

  Reads uncompressed data into an array of bytes. Iflen is not zero, the method will block until some input can be decompressed; otherwise, no bytes are read and0 is returned.

  Overrides:

  read in class InflaterInputStream

  Parameters:

  buf - the buffer into which the data is read

  off - the start offset in the destination arrayb

  len - the maximum number of bytes read

  Returns:

  the actual number of bytes read, or -1 if the end of the compressed input stream is reached

  Throws:

  NullPointerException - Ifbuf isnull.

  IndexOutOfBoundsException - Ifoff is negative,len is negative, orlen is greater thanbuf.length - off

  ZipException - if the compressed input data is corrupt.

  IOException - if an I/O error has occurred.
