        Specified by:
        close in interface java.lang.AutoCloseable
        Specified by:
        close in interface java.io.Closeable
        Overrides:
        close in class java.io.FilterOutputStream

      • flush

        public void flush()
           throws java.io.IOException
        Flushes this output stream, forcing any pending buffered output bytes to be written.
        Specified by:
        flush in interface java.io.Flushable
        Overrides:
        flush in class java.io.FilterOutputStream

        Throws:
        java.io.IOException - if an I/O error occurs or this stream is already closed

      • write

        public void write​(int b)
           throws java.io.IOException
        Writes a byte to the uncompressed output stream.
        Overrides:
        write in class java.io.FilterOutputStream
        Parameters:
        b - a single byte of compressed data to decompress and write to the output stream
        Throws:
        java.io.IOException - if an I/O error occurs or this stream is already closed
        java.util.zip.ZipException - if a compression (ZIP) format error occurs

      • write

        public void write​(byte[] b,
                  int off,
                  int len)
           throws java.io.IOException
        Writes an array of bytes to the uncompressed output stream.
        Overrides:
        write in class java.io.FilterOutputStream
        Parameters:
        b - buffer containing compressed data to decompress and write to the output stream
        off - starting offset of the compressed data within b
        len - number of bytes to decompress from b
        Throws:
        java.lang.IndexOutOfBoundsException - if off < 0, or if len < 0, or if len > b.length - off
        java.io.IOException - if an I/O error occurs or this stream is already closed
        java.lang.NullPointerException - if b is null
        java.util.zip.ZipException - if a compression (ZIP) format error occurs
