方法详细资料

close

public void close()
           throws IOException

指定者:

close 在接口中 Closeable

指定者:

close 在接口中 AutoCloseable

覆盖:

close 在类中 OutputStream

抛出:

IOException

flush

public void flush()
           throws IOException

指定者:

flush 在接口中 Flushable

覆盖:

flush 在类中 OutputStream

抛出:

IOException

write

public abstract void write(byte[] b,
         int off,
         int len)
                    throws IOException

Write compressed bytes to the stream. Made abstract to prevent leakage to underlying stream.

覆盖:

write 在类中 OutputStream

抛出:

IOException

finish

public abstract void finish()
                     throws IOException

Finishes writing compressed data to the output stream without closing the underlying stream.

抛出:

IOException

resetState

public abstract void resetState()
                         throws IOException

Reset the compression to the initial state. Does not reset the underlying stream.

抛出:

IOException
