public interface ChannelBufferIndexFinder
ChannelBuffer
.
This interface enables the sequential search for the data which meets more
complex and dynamic condition than just a simple value matching. Please
refer to ChannelBuffer.indexOf(int, int, ChannelBufferIndexFinder)
and
ChannelBuffer.bytesBefore(int, int, ChannelBufferIndexFinder)
for more explanation.
Modifier and Type | Field and Description |
---|---|
static ChannelBufferIndexFinder |
CR
Index finder which locates a
CR ('\r') byte. |
static ChannelBufferIndexFinder |
CRLF
Index finder which locates a
CR ('\r') or LF ('\n') . |
static ChannelBufferIndexFinder |
LF
Index finder which locates a
LF ('\n') byte. |
static ChannelBufferIndexFinder |
LINEAR_WHITESPACE
Index finder which locates a linear whitespace
(
' ' and '\t' ). |
static ChannelBufferIndexFinder |
NOT_CR
Index finder which locates a non-
CR ('\r') byte. |
static ChannelBufferIndexFinder |
NOT_CRLF
Index finder which locates a byte which is neither a
CR ('\r')
nor a LF ('\n') . |
static ChannelBufferIndexFinder |
NOT_LF
Index finder which locates a non-
LF ('\n') byte. |
static ChannelBufferIndexFinder |
NOT_LINEAR_WHITESPACE
Index finder which locates a byte which is not a linear whitespace
(neither
' ' nor '\t' ). |
static ChannelBufferIndexFinder |
NOT_NUL
Index finder which locates a non-
NUL (0x00) byte. |
static ChannelBufferIndexFinder |
NUL
Index finder which locates a
NUL (0x00) byte. |

The implementation should not perform an operation which raises an
exception such as IndexOutOfBoundsException
nor perform
an operation which modifies the content of the buffer.
