isValidUTF8

public static boolean isValidUTF8(java.nio.ByteBuffer data,
                                  int off)

Check if the provided BytebBuffer contains a valid utf8 encoded string.

Using the algorithm "Flexible and Economical UTF-8 Decoder" by Björn Höhrmann (http://bjoern.hoehrmann.de/utf-8/decoder/dfa/)

参数:

data - the ByteBuffer

off - offset (for performance reasons)

返回:

does the ByteBuffer contain a valid utf8 encoded string

isValidUTF8

public static boolean isValidUTF8(java.nio.ByteBuffer data)

Calling isValidUTF8 with offset 0

参数:

data - the ByteBuffer

返回:

does the ByteBuffer contain a valid utf8 encoded string
