Constructor Detail

FastByteArrayInputStream

public FastByteArrayInputStream(FastByteArrayOutputStream fastByteArrayOutputStream)

Create a new FastByteArrayOutputStreamInputStream backed by the given FastByteArrayOutputStream.

Method Detail

read

public int read()

Specified by:

read in class java.io.InputStream

read

public int read(byte[] b)

Overrides:

read in class java.io.InputStream

read

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

Overrides:

read in class java.io.InputStream

skip

public long skip(long n)
          throws java.io.IOException

Overrides:

skip in class java.io.InputStream

Throws:

java.io.IOException

available

public int available()

Overrides:

available in class java.io.InputStream

updateMessageDigest

public void updateMessageDigest(java.security.MessageDigest messageDigest)

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

Overrides:

updateMessageDigest in class UpdateMessageDigestInputStream

Parameters:

messageDigest - the message digest to update

updateMessageDigest

public void updateMessageDigest(java.security.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.

Overrides:

updateMessageDigest in class UpdateMessageDigestInputStream

Parameters:

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()
