Intercept method calls

阅读更多关于 Intercept method calls

Is there a way of intercepting some method calls without making any code changes around the method itself? I don't need to inject any custom behaviour at runtime, only add custom performance logging to an existing project. You want Aspect Oriented Programming. There are 4 main flavours of AOP Runtime RealProxy based AOP Runtime subclass/virtual method AOP Post Compile IL weave AOP Precompile source code AOP The above are ordered in order of speed of execution (slowest to fastest). Note the last two "should" be the same speed. However I expect the compiler to produce better IL than a Post

How to vary between child and parent view group touch events

阅读更多关于 How to vary between child and parent view group touch events

I decided to post this question and answer in response to this comment to this question: How to handle click in the child Views, and touch in the parent ViewGroups? I will paste the comment here: Suppose I want to override the touch events only for handling some of the children, what can I do inside this function to have it working ? I mean, for some children it would work as usual, and for some, the parent-view will decide if they will get the touch events or not. So the question is this: How do I prevent the parent onTouchEvent() from overriding some child elements' onTouchEvent() , while

Highcharts - Get crossing point of crossing series

阅读更多关于 Highcharts - Get crossing point of crossing series

问题 I am currently trying to extract the points of multiple crossings of series (a,b,c,d) of a specific series (x). I can't seem to find any function that can aid me in this task. My best bet is to measure the distance of every single point in x with every single point in a,b,c,d... and assume when the distance reaches under some threshold, the point must be a crossing point. I think this approach is far too computational heavy and seems "dirty". I believe there must be easier or better ways,
