close
public void close() throws IOException
Writes any remaining uncompressed data to the output stream and closes the underlying output stream.- Specified by:
close
in interfaceCloseable
- Specified by:
close
in interfaceAutoCloseable
- Overrides:
close
in classFilterOutputStream
- Throws:
IOException
- if an I/O error occurs- See Also:
FilterOutputStream.flush()
,FilterOutputStream.out
-
flush
public void flush() throws IOException
Flushes this output stream, forcing any pending buffered output bytes to be written.- Specified by:
flush
in interfaceFlushable
- Overrides:
flush
in classFilterOutputStream
- Throws:
IOException
- if an I/O error occurs or this stream is already closed- See Also:
FilterOutputStream.out
-
finish
public void finish() throws IOException
Finishes writing uncompressed data to the output stream without closing the underlying stream. Use this method when applying multiple filters in succession to the same output stream.- Throws:
IOException
- if an I/O error occurs or this stream is already closed
-
write
public void write(int b) throws IOException
Writes a byte to the uncompressed output stream.- Overrides:
write
in classFilterOutputStream
- Parameters:
b
- a single byte of compressed data to decompress and write to the output stream- Throws:
IOException
- if an I/O error occurs or this stream is already closedZipException
- if a compression (ZIP) format error occurs
-
write
public void write(byte[] b, int off, int len) throws IOException
Writes an array of bytes to the uncompressed output stream.- Overrides:
write
in classFilterOutputStream

- starting offset of the compressed data withinb
len
- number of bytes to decompress fromb
- Throws:
IndexOutOfBoundsException
- ifoff
< 0, or iflen
< 0, or iflen
>b.length - off
IOException
- if an I/O error occurs or this stream is already closedNullPointerException
