java.util.zip.DeflaterOutputStream类实现输出流过滤器，用于以“ deflate”压缩格式压缩数据。它还用作其他类型的压缩过滤器(例如GZIPOutputStream)的基础。
以下是java.util.zip.DeflaterOutputStream类的声明-
public class DeflaterOutputStream
extends FilterOutputStream
以下是java.util.zip.DeflaterOutputStream类的字段-
protected byte [] buf-用于写入压缩数据的输出缓冲区。
受保护的Deflater def-此流的压缩器。
| Sr.No. | Constructor & Description |
|---|---|
| 1 |
DeflaterOutputStream(OutputStream out) Creates a new output stream with a default compressor and buffer size. |
| 2 |
DeflaterOutputStream(OutputStream out, boolean syncFlush) Creates a new output stream with a default compressor, a default buffer size and the specified flush mode. |
| 3 |
DeflaterOutputStream(OutputStream out, Deflater def) Creates a new output stream with the specified compressor and a default buffer size. |
| 4 |
DeflaterOutputStream(OutputStream out, Deflater def, boolean syncFlush) Creates a new output stream with the specified compressor, flush mode and a default buffer size. |
| 5 |
DeflaterOutputStream(OutputStream out, Deflater def, int size) Creates a new output stream with the specified compressor and buffer size. |
| 6 |
DeflaterOutputStream(OutputStream out, Deflater def, int size, boolean syncFlush) Creates a new output stream with the specified compressor, buffer size and flush mode. |
| Sr.No. | Method & Description |
|---|---|
| 1 | void close()
Writes remaining compressed data to the output stream and closes the underlying stream. |
| 2 | void finish()
Finishes writing compressed data to the output stream without closing the underlying stream. |
| 3 | void flush()
Flushes the compressed output stream. |
| 4 | void write(byte[] b, int off, int len)
Writes an array of bytes to the compressed output stream. |
| 5 | void write(int b)
Writes a byte to the compressed output stream. |
