i have implemented outline view in application consist of 200 node. how can search specific node , expand ? i have looked breadthfirstenumeration() , depthfirstenumeration() method of defaultmutabletreenode not find equivalent method in outline. the approach depends on treemodel used construct outlinemodel . in filetreemodel cited, getroot() returns arbitrary file representing root of subtree in hierarchical file system. subtree can searched recursively shown here . instead of printing results, accumulate file instances representing path array. array used construct treepath . given such treepath , can reveal corresponding node in manner analogous shown here . outline.expandpath(treepath); outline.scrollrecttovisible(getpathbounds(treepath));

i'm using jdbc mysql. need iterate on every row in table (60,000 rows, table = innodb), , perform processing on each. will mysql accept query without limit that? in simplest implementation, select entire table, , keep iterating results while cursor gives me more results: preparedstatement stmt = conn.preparestatement("select * foo"); resultset rs = stmt.getresultset(); while (rs.next()) { .. stuff on each row .. } i can implement paging query of course in batches, it'd simpler stated in first approach. wonder if mysql internally, or tries load entire query result set memory first? thanks mysql gonna run , try best sure, or @ least try use our memory until runs out. it's interesting highlight in few other points: even using limit, mysql parser still gonna fullscan in table. limit runs in 1 level after process; mysql gonna try use memory , if not enough, parser swaps filesystem, more slower , expensive in terms of performance; try use i...

have custom table cell it's own .xib , .h , .m. nothing fancy. when device rotates, cell width not change. tables cell index path called, width not changes (say portrait landscape). preventing this? don't want hand set frame size. will post code if need to, maybe can answer out code on one. even if starting app in landscape not set larger width cell. [addition] also not work non-custom cells. self.tableviewselection.autoresizessubviews = true; self.tableviewselection.autoresizingmask = uiviewautoresizingflexiblewidth | uiviewautoresizingflexibleheight; self.view.autoresizessubviews = true; xib table has resizing seemed setup correctly (non-ios6 support). if overriding layoutsubviews or method, don't forget call it's super: override func layoutsubviews() { //... super.layoutsubviews() } not doing result in problem facing.

i have list<t> t custom object cow . right use following code split list based on color . cowgroups = x in cows group x x.color y select y.tolist().tolist(); then take cowgroups , run foreach on set of actions each cow . list comes out ienumerable<list<cow>> what i'm trying do double grouping on initial list<cow> can group base on color , size. result should still ienumerable<list<cow>> , each list<cow> made based on combined pair of color , size. a co-worker recommended tolookup approach, returns list of key/value pairs, , can't seem value part of pair. i guess i'm looking either way go straight collection of lists, or turn result of tolookup approach collection of lists. you can group class contains both attributes: group x new { x.color, x.size } y
