static byte[] |
copyAllBytesFrom(ByteBuffer bb)
Returns a copy of all the bytes from the given
ByteBuffer ,
from the beginning to the buffer's limit; or null if the input is null. |
static byte[] |
copyBytesFrom(ByteBuffer bb)
Returns a copy of the bytes from the given
ByteBuffer ,
ranging from the the buffer's current position to the buffer's limit; or
null if the input is null. |
static byte[] |
fromBase64(String b64Data)
Converts a Base64-encoded string to the original byte data.
|
static byte[] |
fromHex(String hexData)
Converts a Hex-encoded data string to the original byte data.
|
static String |
toBase64(byte[] data)
Converts byte data to a Base64-encoded string.
|
static String |
toHex(byte[] data)
Converts byte data to a Hex-encoded string in lower case.
|

from the beginning to the buffer's limit; or null if the input is null.
The internal states of the given byte buffer will be restored when this method completes execution.
When handling ByteBuffer
from user's input, it's typical to
call the copyBytesFrom(ByteBuffer)
instead of
copyAllBytesFrom(ByteBuffer)
so as to account for the position
of the input ByteBuffer
. The opposite is typically true,
however, when handling ByteBuffer
from withint the
unmarshallers of the low-level clients.
