To use a custom schema, all you need to do is implement one of the SerializationSchema or DeserializationSchema interface. public class MyMessageSchema implements DeserializationSchema<MyMessage>, SerializationSchema<MyMessage> { @Override public MyMessage deserialize(byte[]...

Three different methods of insertion can used with sets. First, a simple insert of the value. This method returns a pair allowing the caller to check whether the insert really occurred. Second, an insert by giving a hint of where the value will be inserted. The objective is to optimize the inser...

All the insertion methods from sets also apply to multisets. Nevertheless, another possibility exists, which is providing an initializer_list: auto il = { 7, 5, 12 }; std::multiset<int> msut; msut.insert(il);

set and multiset have default compare methods, but in some cases you may need to overload them. Let's imagine we are storing string values in a set, but we know those strings contain only numeric values. By default the sort will be a lexicographical string comparison, so the order won't match the n...

There are several ways to search a given value in std::set or in std::multiset: To get the iterator of the first occurrence of a key, the find() function can be used. It returns end() if the key does not exist. std::set<int> sut; sut.insert(10); sut.insert(15); sut.insert(22); ...

The most obvious method, if you just want to reset your set/multiset to an empty one, is to use clear: std::set<int> sut; sut.insert(10); sut.insert(15); sut.insert(22); sut.insert(3); sut.clear(); //size of sut is 0 Then the erase method can be used.  It offers some poss...

/** * requestdata - the data packet expected to be passed in by external system * JSON - data format exchange * stringify() convert javascript object into a string with JSON.stringify() * nlobjError - add in catch block to log exceptions */ function GetCustomerData(requestdata) { ...

workSheet.Cells[1,5,100,5].Copy(workSheet.Cells[1,2,100,2]); Copies column 5 into column 2 Basically Source.Copy(Destination) This would only copy the first 100 rows. Cells[RowStart, ColumnStart, RowEnd, ColumnEnd ] is the format so to copy a row into another row you would just switch the ind...

Adding dependcy To use a gruntplugin, you first need to add it as a dependency to your project. Let's use the jshint plugin as an example. npm install grunt-contrib-jshint --save-dev The --save-dev option is used to add the plugin in the package.json, this way the plugin is always installed aft...

import numpy as np import matplotlib.pyplot as plt # create some data x = np.arange(-2, 20, 0.5) # values of x y1 = map(lambda x: -4.0/3.0*x + 16, x) # values of y1(x) y2 = map(lambda x: 0.2*x**2 -5*x + 32, x) # svalues of y2(x) fig = plt.figure() ax1 = fig.add_subplo...

Import ReactiveFormsModule, and then import { Component, OnInit, OnDestroy } from '@angular/core'; import { FormControl } from '@angular/forms'; import { Subscription } from 'rxjs'; @Component({ selector: 'component', template: ` <input [formControl]="control" /> ...

For those of you that are new to programming in Swift and those of you coming from different programming bases, such as Python or Java, this article should be quite helpful. In this post, we will discuss a simple solution for implementing swift algorithms. Fizz Buzz You may have seen Fizz Buzz wri...

Recall that every transaction contains multiple sublists of data. Now that we can show only sublist data using Main Line, we can further refine our search results to specific sublist data. Most of the sublists included in Transaction results have a corresponding search filter to toggle whether they...

Recoding missing values Regularly, missing data isn't coded as NA in datasets. In SPSS for example, missing values are often represented by the value 99. num.vec <- c(1, 2, 3, 99, 5) num.vec ## [1] 1 2 3 99 5 It is possible to directly assign NA using subsetting num.vec[num.vec == 99]...

A simple GET request. Let's assume the Model from the example above is in the file ./db/models/Article.js. const express = require('express'); const Articles = require('./db/models/Article'); module.exports = function (app) { const routes = express.Router(); routes.get('/articles', (r...

The BigDecimal class contains an internal cache of frequently used numbers e.g. 0 to 10. The BigDecimal.valueOf() methods are provided in preference to constructors with similar type parameters i.e. in the below example a is preferred to b. BigDecimal a = BigDecimal.valueOf(10L); //Returns cached O...

You can create custom dialogs which contains many component and perform many functionality on it. It behaves like second stage on owner stage. In the following example an application that shows person in the main stage tableview and creates a person in a dialog (AddingPersonDialog) prepared. GUIs c...

Making a sequence of HTTP requests has two primary reasons: Requests are depending on each other (the result from one requests is required for a consecutive request). We want to spread server load into multiple requests. 1. Making multiple dependent requests This can be performed usi...
