With these initialization, we will enter the first scenario. Let's look at MainScene. lua. local MainScene = class("MainScene", function() return display.newScene("MainScene")end)function MainScene:ctor() ui.newTTFLabel({text = "Hello, World", size = 64, ali

object in seed. There is only one seed in a CDB. This is similar to the model database in SQL Server. 3, PDBs CDB can have one or more Pdbs,pdbs backwards compatible, and can operate PDBs as before in the database, where only the majority of operations. Each of these components can be called a container. Therefore, root (root) is a container, and seed (seed) is a container, and each PDB is a container. Each container has a unique ID and name in the C

In fact, the New Keyword of JavaScript only does five things. 1. Create an object2. Search for all the methods and attributes on the prototype of the class and copy them to the created

by using arrays we can make a collection of many objects, and we can create a hash table with a name and a worthy index relationship, and when we manage an object with multiple properties, or even create a new object entirely, these methods are somewhat inadequate. To this e

There are two simple ways to create an empty object: var New Object (); and: var obj = {}; The two methods are semantically identical. The second more convenient method is called the "object literal literal" method. This is also the core syntax in JSON format, generally we p

ProgressBar ProgressBar = new ProgressBar (context); Lineanerlayout layout = new LinearLayout (context); Layout.addview (ProgressBar, New Layoutparam (Layoutparam.fill_parent, layoutparam.fill_parent)); .... This creates a ProgressBar

The PHP Data Object (PDO) Extension defines a lightweight and consistent database access interface. each driver that implements the PDO interface shows database-related features like general extension functions. you cannot use the PDO function to execute any database function. You must use a database driver to access the database server.PDO provides a data access abstraction layer, which means that you can use the same function to publish and query da
