Examples of simtools.data.buffer.DelayedBuffer

simtools.data.buffer.DelayedBuffer
Unlike parent's, this buffer deletes old elements and give priority to the newly set elements. The Simple and Resizeable buffre only sets new values if possible, this buffer always takes in account new values, even if old ones are dropped in the process. Also, setSlice will bound the buffer size.
