i'm looking build pipeline pattern scala. wish after write pipeline objects, connected this: pipeline1 :: pipeline2 :: pipeline3 ... i have experimented few ideas far. work , don't. none of them seems rid of boilerplate code. following closest i've got. first define pipeline , source abstract class: // input type , o output type of pipeline abstract class pipeline[i, +o](p: pipeline[_, _ <: i]) { val source = p val name: string def produce(): o def stats():string } abstract class source[+t] extends pipeline[anyref, t](null) next, created 2 pipelines , try link them together // creates random integer class randominteger extends source[int] { override val name = "randint" def produce() = { scala.math.round(scala.math.random.asinstanceof[float] * 10) } def stats()="this pipeline stateless" } // multiply ten class timesten(p: pipeline[_, int]) extends pipeline[int, int](p) { private var count = 0 // simple state o...

i have package r i've been developing under linux, , horrible time has come i'm testing under windows. the documentation done using roxygen, , using cygwin build package. the thing is, when roxygenise('test-package') , roxygen truncates \usage section of documentation 1 character. not of functions, , can't figure out pattern. this not occur when run same command (i.e. roxygenise('test-package') r prompt) under linux or windows - cygwin under windows (using r devtools + command prompt windows isn't option me - it's part of big project makefiles etc). in cases, using roxygen v2.2.2. update: this appears occur function default parameter. i've boiled down 1 reproducible example, trimmed down as possible isolate problem: from r: # function used trim strings, i've stripped right down # eliminate cause of problem trim <- function(x='asdf') { return( x ) } package.skeleton('test') modify trim.r (i...

i have noticed jquery , related keynote plugins jquery.ui pass undefined parameter anonymous functions used in module definitions, so: (function($, undefined) { ... })(jquery); alternatively, have noticed other plugins recommended jquery and/or others not pass undefined in parameter. this silly question, but... shouldn't available anyway? why pass in? there sort of other purpose or trick going on here? there 2 reasons that: 1) if undefined variable in function scope rather global object property, minifiers can reduce single letter achieving better compression rate. 2) before es5*, undefined property of global object without write-protection. overwritten, resulting in strange , unexpected behavior. this: var test = 123; undefined = 123; if (test === undefined){ // true, since undefined equals 123 } by having function argument undefined (the name not matter) don't pass parameter to, make sure have variable undefined can test "undefine...

i want add custom annotationview callout contains 1. title 2. subtitles 3. button the button can display on right ( rightcalloutaccessoryview ) or left leftcalloutaccessoryview sides of callout. want add button in middle of callout , under title->subtitle. how can do? there no api this. try not using standard callout (canshowcallout = no), catch taps , drags on annotationview manually , show own ui adding custom views based on position of annotationview. seems fragile, though.
