Method Summary

Modifier and Type	Method and Description
static char[]	readUtf8(ByteBuf byteBuf, int length)
static int	utf8Bytes(char[] seq) Returns the exact bytes length of UTF8 character sequence.
static int	utf8Bytes(char[] seq, int start, int end) This method is producing the exact length according to writeUtf8(ByteBuf, char[], int, int).
static int	writeUtf8(ByteBuf buf, char[] seq) Encode a char[] in UTF-8 and write it into ByteBuf.
static int	writeUtf8(ByteBuf buf, char[] seq, int start, int end) Equivalent to writeUtf8(buf, seq.subSequence(start, end), reserveBytes) but avoids subsequence object allocation if possible.

Method Detail

utf8Bytes

public static int utf8Bytes(char[] seq)

Returns the exact bytes length of UTF8 character sequence.

This method is producing the exact length according to writeUtf8(ByteBuf, char[]).

utf8Bytes

public static int utf8Bytes(char[] seq,
                            int start,
                            int end)

This method is producing the exact length according to writeUtf8(ByteBuf, char[], int, int).

writeUtf8

public static int writeUtf8(ByteBuf buf,
                            char[] seq)

Encode a char[] in UTF-8 and write it into ByteBuf.

This method returns the actual number of bytes written.

writeUtf8

public static int writeUtf8(ByteBuf buf,
                            char[] seq,
                            int start,
                            int end)

Equivalent to writeUtf8(buf, seq.subSequence(start, end), reserveBytes) but avoids subsequence object allocation if possible.

Returns:

actual number of bytes written

readUtf8

public static char[] readUtf8(ByteBuf byteBuf,
                              int length)
