InflaterOutputStream (OutputStream out)
用默认的解压缩器和缓冲区大小创建一个新的输出流。
| 参数(Parameters) | |
|---|---|
out |
OutputStream: output stream to write the uncompressed data to |
| 抛出异常(Throws) | |
|---|---|
NullPointerException |
if out is null |
InflaterOutputStream (OutputStream out, Inflater infl)
使用指定的解压缩器和默认缓冲区大小创建新的输出流。
| 参数(Parameters) | |
|---|---|
out |
OutputStream: output stream to write the uncompressed data to |
infl |
Inflater: decompressor ("inflater") for this stream |
| 抛出异常(Throws) | |
|---|---|
NullPointerException |
if out or infl is null |
InflaterOutputStream (OutputStream out, Inflater infl, int bufLen)
用指定的解压缩器和缓冲区大小创建一个新的输出流。
| 参数(Parameters) | |
|---|---|
out |
OutputStream: output stream to write the uncompressed data to |
infl |
Inflater: decompressor ("inflater") for this stream |
bufLen |
int: decompression buffer size |
| 抛出异常(Throws) | |
|---|---|
IllegalArgumentException |
if bufLen is <= 0 |
NullPointerException |
if out or infl is null |
void close ()

| 抛出异常(Throws) | |
|---|---|
IOException |
if an I/O error occurs |
void finish ()

IOException |
if an I/O error occurs or this stream is already closed |
void flush ()
刷新此输出流，强制写入任何未决的缓冲输出字节。
| 抛出异常(Throws) | |
|---|---|
IOException |
if an I/O error occurs or this stream is already closed |
