方法详细资料

bytes

public static byte[] bytes(java.lang.String str)

Convert a String to a UTF-8 byte array.

参数:

str - the string

返回:

the byte array.

memcmp

public static int memcmp(java.nio.ByteBuffer x,
                         java.nio.ByteBuffer y,
                         int count)

Compares the first count bytes of two areas of memory. Returns zero if they are the same, a value less than zero if x is lexically less than y, or a value greater than zero if x is lexically greater than y. Note that lexical order is determined as if comparing unsigned char arrays. Similar to memcmp.c.

参数:

x - the first value to compare with

y - the second value to compare against

count - the number of bytes to compare

返回:

the result of the comparison
