问题 WSO2 ESB has Mediation Sequences and Proxy Services for implementing EAI patterns. I am currently new and couldn't distinguish when to use a Mediation Sequence or Proxy Service. Both seem to work well in most of the use cases. When should I use each? 回答1: Sequence (Mediation Sequence) is a sequence of Mediators. A message comes into the sequence, passes through the each mediator, in the order they are located in the sequence. So a Mediation Sequence is the generic building material of WSO2

问题 I'm a trying to compare fingerprints. Here's what I got so far. Get the raw image from a digitalPersona sensor. image Binarize it. image Skeletonize it. I used Hall's algorithm because that is the only one I got to work more or less properly. You can still see some flaws. image Strip the convex hull (inverted Jarvis algorithm) and get all the ridge endings as an array of (i, j) coordinates (points with one neighbour only). I also have a script to get the bifurcations (3 neighbours).

问题 Lets say I have a list of Vendors : Asda, Tesco, Spar. And I have a list of Sources (or suppliers in this analogy): Kellogg, Cadbury, Nestle, Johnsons, Pampers, Simple, etc. (there is a defined list of around 20). Elsewhere in the flow of data. I am returning a result, which is Yes/No for each vendor, for multiple different things. For example: Asda: ukOnly = "Yes"; Spar: ukOnly = "No" etc. In this specific section, I am collating results. Mostly it doesn't matter if the sources from the

问题 Consider this code: int a = 0; short b = 0; int c = 0; object a1 = a; object b1 = b; object c1 = c; Console.WriteLine(1); //comparing primitives - int vs. short Console.WriteLine(a == b); Console.WriteLine(b == a); Console.WriteLine(a.Equals(b)); Console.WriteLine(b.Equals(a)); Console.WriteLine(2); //comparing objects - int vs. int Console.WriteLine(c1 == a1); Console.WriteLine(a1 == c1); Console.WriteLine(c1.Equals(a1)); Console.WriteLine(a1.Equals(c1)); Console.WriteLine(3); //comparing

问题 I'm trying to make a method that can compare any two lists for equality. I'm trying to compare them in a way that validates that every element of one list has the same value as every element of another list. My Equals method below always returns false , can anyone see why that is? using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; public class IEnumerableComparer<T> : IEqualityComparer<IEnumerable<T>> { public bool Equals

问题 I've seen some sites where they show two random items from a list, and users pick which one they prefer, and then based on the results of the user preferences, a ranking is generated for the entire data set. Does anyone know what this ranking algorithm is called and how it works? Thank you. 回答1: I believe you're referring to the ELO rating system. 回答2: A simple implementation would be to always choose two random items for the comparison and give the preferred item a point. Then rank in order

问题 I have the following query in SQLite: SELECT * FROM t1 ORDER BY t1.field Where t1.field is a text column containing numbers. Is it posible to force SQLite to consider the values of t1.field as numbers instead of strings (whithout doing ALTER TABLE )? Right now the sort is a pure string one, so 10 goes before 2. Thank you. 回答1: Well, found a solution: SELECT * FROM t1 ORDER BY t1.field + 0 The + 0 part seems to force conversion to number 来源： https://stackoverflow.com/questions/4204319/compare

问题 This question already has answers here : How to read and write excel file (20 answers) Closed 5 years ago . I want to write a program that compares two Microsoft Excel sheets using Java. Is there any existing library (and its documentation) that can help me get started with basic stuffs like reading all the rows and columns of the excel ? 回答1: Have a look at Apache POI, which is a Java API for Microsoft Documents. And here is a tutorial on how to setup and get started with Excel files. 回答2: 1
