Parameters:

data - the storage.

Returns:

the buffer.

Throws:

BadParameterException

NoSuccessException

doCreateBuffer

protected abstract Buffer doCreateBuffer(int size)
                                  throws BadParameterException,
                                         NoSuccessException

data - the storage.

Returns:

the buffer.

Throws:

NoSuccessException - is thrown when the operation was not successfully performed, and none of the other exceptions apply.

BadParameterException - is thrown when the implementation cannot handle the specified data buffer.
