InflaterOutputStream
public InflaterOutputStream(OutputStream out)
Creates a new output stream with a default decompressor and buffer size.- Parameters:
out- output stream to write the uncompressed data to- Throws:
NullPointerException- ifoutis null
-
InflaterOutputStream
public InflaterOutputStream(OutputStream out, Inflater infl)
Creates a new output stream with the specified decompressor and a default buffer size.- Parameters:
out- output stream to write the uncompressed data toinfl- decompressor ("inflater") for this stream- Throws:
NullPointerException- ifoutorinflis null
-
InflaterOutputStream

close
public void close() throws IOExceptionWrites any remaining uncompressed data to the output stream and closes the underlying output stream.- Specified by:
closein interfaceAutoCloseable- Specified by:
closein interfaceCloseable- Overrides:
closein classFilterOutputStream- Throws:
IOException- if an I/O error occurs- See Also:
FilterOutputStream.flush(),FilterOutputStream.out
-
flush
public void flush() throws IOExceptionFlushes this output stream, forcing any pending buffered output bytes to be written.- Specified by:
flushin interfaceFlushable- Overrides:
flushin classFilterOutputStream- Throws:
IOException- if an I/O error occurs or this stream is already closed- See Also:
FilterOutputStream.out
-
finish
public void finish() throws IOExceptionFinishes 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 IOExceptionWrites a byte to the uncompressed output stream.- Overrides:
writein 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 IOExceptionWrites an array of bytes to the uncompressed output stream.- Overrides:
writein classFilterOutputStream- Parameters:
b- buffer containing compressed data to decompress and write to the output streamoff- starting offset of the compressed data withinblen- number of bytes to decompress fromb- Throws:
IndexOutOfBoundsException- ifoff < 0, or iflen < 0, or iflen > b.length - offIOException- if an I/O error occurs or this stream is already closedNullPointerException- ifbis nullZipException- if a compression (ZIP) format error occurs- See Also:
