构造器

构造器	说明
InflaterOutputStream(OutputStream out)	Creates a new output stream with a default decompressor and buffer size.
InflaterOutputStream(OutputStream out, Inflater infl)	Creates a new output stream with the specified decompressor and a default buffer size.
InflaterOutputStream(OutputStream out, Inflater infl, int bufLen)	Creates a new output stream with the specified decompressor and buffer size.

方法概要

限定符和类型	方法	说明
void	close()	Writes any remaining uncompressed data to the output stream and closes the underlying output stream.
void	finish()	Finishes writing uncompressed data to the output stream without closing the underlying stream.
void	flush()	Flushes this output stream, forcing any pending buffered output bytes to be written.
void	write(byte[] b, int off, int len)	Writes an array of bytes to the uncompressed output stream.
void	write(int b)	Writes a byte to the uncompressed output stream.

构造器详细资料

InflaterOutputStream

public InflaterOutputStream(OutputStream out)

Creates a new output stream with a default decompressor and buffer size.

参数:

out - output stream to write the uncompressed data to

抛出:

NullPointerException - if out is null

InflaterOutputStream

public InflaterOutputStream(OutputStream out,
                            Inflater infl)

Creates a new output stream with the specified decompressor and a default buffer size.

参数:

out - output stream to write the uncompressed data to

infl - decompressor ("inflater") for this stream

抛出:

NullPointerException - if out or infl is null

InflaterOutputStream

public InflaterOutputStream(OutputStream out,
                            Inflater infl,
                            int bufLen)

Creates a new output stream with the specified decompressor and buffer size.

参数:

out - output stream to write the uncompressed data to

infl - decompressor ("inflater") for this stream

bufLen - decompression buffer size

抛出:

IllegalArgumentException - if bufLen <= 0

NullPointerException - if out or infl is null

方法详细资料

close

public void close()
           throws IOException

Writes any remaining uncompressed data to the output stream and closes the underlying output stream.

指定者:

close 在接口中 AutoCloseable

指定者:

close 在接口中 Closeable

覆盖:

close 在类中 FilterOutputStream

抛出:

IOException - if an I/O error occurs

另请参阅:

FilterOutputStream.flush(), FilterOutputStream.out

flush

public void flush()
           throws IOException

Flushes this output stream, forcing any pending buffered output bytes to be written.

指定者:

flush 在接口中 Flushable

覆盖:

flush 在类中 FilterOutputStream

抛出:

IOException - if an I/O error occurs or this stream is already closed

另请参阅:

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.

抛出:

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.

覆盖:

write 在类中 FilterOutputStream

参数:

b - a single byte of compressed data to decompress and write to the output stream

抛出:

IOException - if an I/O error occurs or this stream is already closed

ZipException - 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.

覆盖:

write 在类中 FilterOutputStream

参数:

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

抛出:

IndexOutOfBoundsException - if off < 0, or if len < 0, or if len > b.length - off

IOException - if an I/O error occurs or this stream is already closed

NullPointerException - if b is null

ZipException - if a compression (ZIP) format error occurs
