checkIndex(int index)
Convenience method for checking if we can get the byte at the specified
index.
|
Buffer |
clone()
Performs a deep clone of this object.
|
String |
dumpAsHex()
Dump the content of this buffer as a hex dump ala Wireshark.
|
boolean |
equals(Object other)
Check whether to buffers are considered to be equal.
|
boolean |
equalsIgnoreCase(Object other) |
byte[] |
getArray()
Get the backing array.
|
byte |
getByte(int index)
Get the byte at the index.
|
void |
getBytes() |
void |
getBytes(Buffer dst)
Same as calling
Buffer.getBytes(int, Buffer) where the index is
Buffer.getReaderIndex(). |
void |
getBytes(byte[] dst) |
void |
getBytes(int index,
Buffer dst)
Transfer this buffer's data to the destination buffer.
|
int |
getInt(int index)
Get a 32-bit integer at the specified absolute index.
|
int |
getReadableBytes()
Returns the number of available bytes for reading without blocking.
|
short |
getShort(int index) |
short |
getUnsignedByte(int index) |
long |
getUnsignedInt(int index) |
int |
getUnsignedShort(int index) |
int |
getWritableBytes()
Get the number of writable bytes.
|
int |
hashCode() |
boolean |
hasReadableBytes()
Checks whether this buffer has any bytes available for reading without
blocking.
|
boolean |
hasWritableBytes()
Checks whether this
Buffer has any space left for writing. |
boolean |
isEmpty()
Check whether this buffer is empty or not.
|
byte |
peekByte()
Peak a head to see what the next byte is.
|
byte |
readByte()
Read the next byte, which will also increase the readerIndex by one.
|
Buffer |
readBytes(int length)
Read the requested number of bytes and increase the readerIndex with the
corresponding number of bytes.
|
int |
readInt()
Read an int and will increase the reader index of this buffer by 4
|
short |
readShort() |
long |
readUnsignedInt()
Read an unsigned int and will increase the reader index of this buffer by
4
|
int |
readUnsignedShort() |
void |
setByte(int index,
byte value)
Set the byte at given index to a new value
|
void |
setInt(int index,
int value) |
void |

short value) |
void |
setUnsignedInt(int index,
long value) |
void |
setUnsignedShort(int index,
int value) |
Buffer |
slice(int start,
int stop)
Get a slice of the buffer starting at
start (inclusive)
ending at stop (exclusive). |
String |
toString() |
void |
write(byte[] bytes) |
void |
write(int value) |
void |
write(long value) |
void |
writeAsString(int value)
Write the integer value to this
Buffer as a String. |
void |
writeAsString(long value)
Write the long value to this
Buffer as a String. |

InputStreamBuffer gets its bytes off of a InputStream so
let's say you have read 10 bytes off of the stream already but ask to
access the byte at index 20, we will try and ready an additional 10 bytes
from the InputStream so we can return the byte at index 20.IndexOutOfBoundsException - in case the index is greater than the capacity of this bufferIOExceptionprotected void checkIndex(int index)

InputStream. If that fails, e.g. we don't ready
enough bytes off of the stream, then we will eventually throw an
