according solr's blog , lucene requires tokenfilter subclasses must declared final. advantage of final classes in context? makes impossible extend functionality of existing tokenfilter. tokenfilter extends tokenstream , , javadoc says: the tokenstream -api in lucene based on decorator pattern. therefore non-abstract subclasses must final or have @ least final implementation of incrementtoken() ! checked when java assertions enabled. for example, standardfilter not marked final (only incrementtoken() is). so if want extend existing tokenfilter it's best via delegation.

i'm looking behaviour similar pinned gmail tabs, tab head blinks when there's new email , tab not in focus. chrome.windows.update(..) has 'drawattention' option. chrome.tabs.update(..) has 'active' , 'highlight' options. i couldn't locate method of indicating updated tab in active window without switching it/or highlighting (which seems have similar behaviour active). i'm afraid highlighting far tabs api goes. you use content script show annoying animated favicon until tab gets visible possible workaround.

this might simple question i've been thinking lately. i've tried researching answer have yet find satisfactory one. basically, what's happening behind scene when call function? say:- function sayhello(){ console.log('hello'); } sayhello(); //what's happening here? i know doing sayhello.call(); or sayhello.apply(); same thing doing sayhello(); there more information on what's happening underneath or behind mysterious native code? here of things interpreter make js function call: a new scope object created. arguments object created , put scope object arguments passed function in it. any local variables in new function put scope object. a reference next line of code pushed onto execution stack (so interpreter knows go when function returns). the pointer set appropriate. execution transferred code of function. this managed internals of js interpreter (one of many jobs) native code. if want call function b() anytime functio...
