方法详细资料

updateMessageDigest

public void updateMessageDigest(java.security.MessageDigest messageDigest)
                         throws java.io.IOException

Update the message digest with the rest of the bytes in this stream.

Using this method is more optimized since it avoids creating new byte arrays for each call.

参数:

messageDigest - The message digest to update

抛出:

java.io.IOException - when propagated from InputStream.read()

updateMessageDigest

public void updateMessageDigest(java.security.MessageDigest messageDigest,
                                int len)
                         throws java.io.IOException

Update the message digest with the next len bytes in this stream.

Using this method is more optimized since it avoids creating new byte arrays for each call.

参数:

messageDigest - The message digest to update

len - how many bytes to read from this stream and use to update the message digest

抛出:

java.io.IOException - when propagated from InputStream.read()
