| resetBuffer | | public void resetBuffer()(Code) | | Clears the buffer by setting the size of the filled area to zero.
The reading marker's position is not affected by this method so if
the reading marker was not positioned to the beginning of the buffer
it'll become to be in invalid position.
|
| resetParser | | public void resetParser()(Code) | | Moves the reading marker to the beginning of the buffer.
Typically the process of reading data from the buffer is
organized as follows: at first move the reading marker to the
some start position (for example, in the beginning of the buffer)
and then consequently read the data using get methods (for example,
getInt()). So the process of reading data from the byte
buffer is looks like reading data from generic stream (for example,
from file).

Parameters:
i - index of the buffer where reading marker should point |
| toString | | public String toString(int start)(Code) | | Returns string representation of the contents of the buffer from
the specified index. This method is invoked by KJDB when JDWP reply
packet is not received (usually it's a fatal error)and this information
is useful for localizing the problem.

start - the first index that should be printed string representation of a part of the byte buffer
See Also: jdwp.BackEndTest.printReplies |
| toString | | public String toString()(Code) | | Returns string representation of the object. Currently this method is
not used by KJDB but it may be useful for debugging purposes.
