matcher

问题 The Documentation of OpenCV mentions the function "train()" within a DescriptorMatcher. "virtual void cv::cuda::DescriptorMatcher::train ( ) pure virtual Trains a descriptor matcher. Trains a descriptor matcher (for example, the flann index). In all methods to match, the method train() is run every time before matching."(docs) That's all is said there. Does someone know hot it works? Especially what the DescriptorMatcher needs to train itself. A short example in some OOP language would be

问题 This is a follow up to an original question I posted here, but I would appreciate help in expanding its capabilities a bit. I have the following string I am trying to capture from (let's call it output): ltm pool TEST_POOL { Some strings above headers records { baz:1 { ANY STRING HERE session-status enabled } foobar:23 { ALSO ANY STRING HERE session-status enabled } } members { qux:45 { ALSO ANY STRINGS HERE session-status enabled } bash:2 { AND ANY STRING HERE session-status user-disabled }

问题 Actually I have the following regex tokens (school duty): Identificator = [a-zA-Z_][a-zA-Z0-9_]* Integer = [0-9]+ ReservedKeywords = true|false|while|foreach|for|plus Symbols = *|/|-|\(|\)| Blank = \s+ I can't use the Scanner class because there may be no whitespaces between certain tokens. Note that Parser (given it receives correct tokens) is ready, and also typechecking and evaluation of the AST. Only the "simplest" part is missing so "Tokenizer" and there are not enough complete enough

问题 Is there a variant of the RSpec start_with matcher that will use regular expression matching instead of equality when examining arrays of strings? (I don't mind writing my own; but I don't want to re-invent the wheel.) Specifically, I want to have a spec that looks like this: it 'begins with the standard header' do output = method_under_test # output is an array of Strings expect(output).to start_with([/foo/, /bar/]) end This spec should pass if output[0] matches /foo/ and output[1] matches

问题 I am facing issue while expecting a setAttribute call from a mock. MyClass { public final void setAttribute(String name, Object value) { // Do Something } myClass.setAttribute("Key", "Value"); While invoking the setAttribute operation, String is passed as a value. I have a mock of the above class by the name mockMyClass and in my Expectations block I have the below code. oneOf(mockMyClass).setAttribute(with(equal("Key")), with(equal("Value"))); I have also tried using any, just to see if the

问题 What is the regular expression that can match the following 2 strings. Hi<Dog>Hi and <Dog> in a given text. Update: What regex will match this one? <FONT FACE="Verdana" SIZE="16" COLOR="#0B333C" LETTERSPACING="0" KERNING="0">If you access the web site click the link below:<FONT SIZE="12"></FONT></FONT> <FONT.*?<\/FONT> matches only till the first </FONT> 回答1: The pattern ^([a-z]*)<[A-Z]*>\1$ will match these strings (as seen on rubular.com): ab<XYZ>ab <XYZ> bleh<FOO>bleh <> It will not match

问题 In vanilla Scala the following assertions pass assert(1D > 0F) assert(1F > 0) assert(1L > 0) assert(1 > 0.toShort) assert(1.toShort > 0.toChar) however similar matchers in ScalaTest fail 1D shouldBe > (0F) 1F shouldBe > (0) 1L shouldBe > (0) 1 shouldBe > (0.toShort) 1.toShort shouldBe > (0.toChar) A workaround is to make both sides the same type, for example 1D shouldBe > (0D) Why does it work in Scala, but not in Scalatest, or what is it about the signature of > def >[T : Ordering] (right: T

问题 I'm new to Spring JPA. I has two questions about Example and ExampleMatcher API. Are there any ways to ignore all paths except some paths which I set matchers. Or are there any ways to ignore all paths if Example object's path has null value. It is quite annoying to set all path names like below: ExampleMatcher<Product> matcher =ExampleMatcher.matching().ignorePaths("field_a", "field_b"); How to match joined column using Example. For example. Product entity has User entity field as @ManyToOne

问题 String original = "This is a sentence.Rajesh want to test the application for the word split."; List matchList = new ArrayList(); Pattern regex = Pattern.compile(".{1,10}(?:\\s|$)", Pattern.DOTALL); Matcher regexMatcher = regex.matcher(original); while (regexMatcher.find()) { matchList.add(regexMatcher.group()); } System.out.println("Match List "+matchList); I need to parse text into an array of lines that do not exceed 10 characters in length and should not have a break in word at the end of

问题 I'm using hamcrest 1.3 . Its implementation of matches(Object o, Description mismatch) looks like that: @Override public boolean matches(Object o, Description mismatch) { for (Matcher<? super T> matcher : matchers) { if (!matcher.matches(o)) { mismatch.appendDescriptionOf(matcher).appendText(" "); matcher.describeMismatch(o, mismatch); return false; } } return true; } When describing mismatch, it first appends the description of matcher that failed, and only then the actual mismatch. This
