java.util.zip
Class GZIPOutputStreamjava.lang.Object
public class GZIPOutputStream extends DeflaterOutputStreamThis class implements a stream filter for writing compressed data in the GZIP file format. 实现以GZIP格式写入压缩数据的流过滤器的类。
Field Summary
protected CRC32
CRC-32 of uncompressed data. 用于解压数据的CRC-32。
Fields inherited from class java.util.zip.DeflaterOutputStream
Fields inherited from class java.io.FilterOutputStream
Constructor Summary
GZIPOutputStream(OutputStream out)
Creates a new output stream with a default buffer size. 使用默认缓冲大小创建输出流。
GZIPOutputStream(OutputStream out, int size)
Creates a new output stream with the specified buffer size. 使用指定缓冲大小创建输出流。
Method Summary
void
finish()
Finishes writing compressed data to the output stream without closing the underlying stream. 完成已压缩数据对输出流的写入但不关闭底层流。
void
,]write(byte[] buf, int off, int len)
Writes array of bytes to the compressed output stream. 将字节数组写入压缩输出流。

Constructor Detail
GZIPOutputStreampublic GZIPOutputStream(OutputStream out,
int size)
throws IOException
Creates a new output stream with the specified buffer size. 使用指定缓冲大小创建输出流。
Parameters: out - the output stream 输出流 size - the output buffer size 输出缓冲大小 Throws: IOException - If an I/O error has occurred. 如果发生I/O错误抛出。 IllegalArgumentException - if size is <= 0 如果大小<= 0抛出GZIPOutputStreampublic GZIPOutputStream(OutputStream out)
throws IOException
Creates a new output stream with a default buffer size. 使用默认缓冲大小创建输出流。
Parameters: out - the output stream 输出流 Throws: IOException - If an I/O error has occurred. 如果发生I/O错误抛出。Method Detail
writepublic void write(byte[] buf,
int off,
int len)
throws IOException
Writes array of bytes to the compressed output stream. This method will block until all the bytes are written. 将字节数组写入压缩输出流。方法阻塞直到所有字节被写入。
Overrides: ,]write in class DeflaterOutputStreamParameters: buf - the data to be written 要写入的数据 off - the start offset of the data 数据的起始偏移 len - the length of the data 数据大小 Throws: IOException - If an I/O error has occurred. 如果发生I/O错误抛出。finishpublic void finish()
throws IOException
Finishes writing compressed data to the output stream without closing the underlying stream. Use this method when applying multiple filters in succession to the same output stream. 完成已压缩数据对输出流的写入但不关闭底层流。当在同一个输出流上连续应用多个过滤器时使用此方法。
