[scopehal-apps] azonenberg e2b4881 - Initial serialization support for MemoryFilter
<azonenberg>
ok sooo thinking a bit more about the trend filter, i know i was talking about this with lain and juh: i think the new idea is to make a new class for a "pausable" filter
<azonenberg>
PausableFilter will inherit from ActionProvider and Filter, and will have actions for run, run single, and pause
<azonenberg>
and have a method that the filter can call which determines if the current refresh call should do anything or return immediately without changing state
<azonenberg>
TrendFilter will then inherit from PausableFilter and update the trend whenever the PausableFilter API says we want to update
<azonenberg>
It will also be serialized just like a memory filter, so you can load the previous trend data when you open the file
<azonenberg>
And then we'll have trigger groups support PausableFilter's so you can start/stop them with the trigger group
