构造器详细资料

FastByteArrayInputStream

public FastByteArrayInputStream(FastByteArrayOutputStream outputStream)

Create a new FastByteArrayOutputStreamInputStream backed by the given FastByteArrayOutputStream.

方法详细资料

read

public int read()

指定者:

read 在类中 InputStream

read

public int read(@NonNull
 byte[] b)

覆盖:

read 在类中 InputStream

read

public int read(@NonNull
 byte[] b,
 int off,
 int len)

覆盖:

read 在类中 InputStream

skip

public long skip(long n)
          throws IOException

覆盖:

skip 在类中 InputStream

抛出:

IOException

available

public int available()

覆盖:

available 在类中 InputStream

updateMessageDigest

public void updateMessageDigest(MessageDigest messageDigest)

Update the message digest with the remaining bytes in this stream.

覆盖:

updateMessageDigest 在类中 FastByteArrayOutputStream.UpdateMessageDigestInputStream

参数:

messageDigest - the message digest to update

updateMessageDigest

public void updateMessageDigest(MessageDigest messageDigest,
 int len)

Update the message digest with the next len bytes in this stream. Avoids creating new byte arrays and use internal buffers for performance.

覆盖:

updateMessageDigest 在类中 FastByteArrayOutputStream.UpdateMessageDigestInputStream

参数:

messageDigest - the message digest to update

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

updateCurrentBufferLength

private void updateCurrentBufferLength()
