according wikipedia dependency relationship shows element, or set of elements, requires other model elements specification or implementation.[1] element dependent upon independent element, called supplier . so not same unidirectional association? use dependency when operation in 1 class uses object of other class parameter? how unidirectional association , dependency different. example helpful association means 2 associated entities linked semantically. dependency declares there a... well, dependency of sort. associations dependencies, while dependency not mean association. example, class 'a' depends on class 'b' if has method takes 'b' , passes argument function in class. if 'a' calls method of class 'b', should modeled association. disclaimer have read uml specification , asked myself question number of times. arrived @ at definition above, i'm still not sure 100% correct.

hej folks, i wondering faster. suggest have big database table 50 columns , class handles these columns. the class constructor loads fields - , here starts question. is useful store every column in own class variable or juts unperformant? in case have array, e.g. $result keys table columns. or irrelevant? i tried write benchmark have vserver test results not clear. is 1 time function stores values in class vars faster searching whole array every 'get' method? thanks in advance :) p.s. php 5 i think answer question "it doesn't matter". in terms of application performance, code you're talking - iterating on loop in memory 50 times , manipulating data in memory, retrieving class data, or retrieving data associative array - blazingly fast. fast it's impossible measure differences under normal circumstances. in order notice difference between employee::$id, employee::$name vs employee::$result['id'], employee::$result[

i want highlight nodes covered given xpath in html page source. i looked in htmlunit, not find thing in api. at present, thinking of doing following way: get xpath , page-source. break xpath smaller chunks , store them in xpath_chunk[]. apply chunk xpath_chunk[] starting 0. update css property of each node found each chunk(any change distinguishes text). now add next chunk , concate current. go step 3. in way, visit nodes covered xpath. more changes can remove elements unnecessarily highlighted. this complicated. there way ? i made rudimentary implementation using javafx's webengine + webview. register dom listener nodes of loaded website's document, can listen clicks on nodes. when clicking, change style of node , add css. webview reflect changes , render page correctly. the document webengine returns can accessed using xpath (it's w3d document), can traverse , modify nodes encounter (or use node furthest down, travel upwards using getparent
