HashingOutputStream

public HashingOutputStream(StreamingHasher hasher,
                           OutputStream out)

Creates an output stream that hashes using the given StreamingHasher, and forwards all data written to it to the underlying OutputStream.

The OutputStream should not be written to before or after the hand-off.

HashingOutputStream

public HashingOutputStream(StreamingHasher hasher,
                           Integer seed,
                           OutputStream out)

方法详细资料

write

public void write(int b)
           throws IOException

覆盖:

write 在类中 FilterOutputStream

抛出:

IOException

write

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

覆盖:

write 在类中 FilterOutputStream

抛出:

IOException

getHash

public long getHash()

Returns the hash code based on the data written to this stream. The result is unspecified if this method is called more than once on the same instance.

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 FilterOutputStream

抛出:

IOException
