Member Function Documentation

template<class E> void oln::utils::buffer::add (  const E &  e, bool  count = true )  [inline]

Add every bits of e in data. e Element to work on. count Tell if you want to count e size in the buffer size. Definition at line 167 of file buffer.hh.

void oln::utils::buffer::push_back (  bool  bit, bool  is_padding = false )  [inline]

Push back a bit at the end of the buffer. true -> push back a 1 false -> push back a 0 bit Bit to push. is_padding Are you adding padding bytes ? Definition at line 181 of file buffer.hh.

buffer::value_type oln::utils::buffer::reorder (  value_type  x  )  const [inline, protected]

Change order of data in a word. x Data to reorder. Definition at line 211 of file buffer.hh.
