What is an iterator pattern? Iterator design patterns can help construct specific objects that can provide a single standard interface loop or iterate over any type of data that can be counted. Iterator pattern problems and solutions: iterator design Patterns help style objects work with collections of data or other objects. When you create a class that is based on an iterator design pattern, we also create a set of interfaces to provide a uniform way to manage these collections. In some cases, datasets seem to be very simple. Programmers will not be able to anticipate what is going to change, so they choose not to modify the code and not create iterators. This is often the case when the database is called. At this point, the programmer creates the MySQL query and then executes a simple fetch array command. However, keeping such procedural methods in your code is not the best solution. You should create an iterator object when working with a MySQL result set. It is relatively straightforward to provide a MySQL query for the class constructor and then iterate through the loop result set by invoking the public method of the iterator object. A more complex iterator example might also have additional parameters to send to the iterator, which, depending on these conditions, might execute different sets of MySQL queries. But anyway, the external

2. Java String Explanation

Summary: In Java, strings are treated as objects of type string. The string class is in the Java.lang package, which is automatically imported into all programs by default.

3.. Net garbage collection Mechanism principle (ii)

Introduction: The previous article introduced the fundamentals of. Net garbage collection and the internal mechanism of garbage collection to perform a Finalize method; we look at weak reference objects, generation, multi-threaded garbage collection, large object processing, and performance counters related to garbage collection.

4.. Net garbage collection and large object handling

Summary: The CLR garbage collector divides objects by the amount of space they occupy. Large objects and small objects are handled in a very different way. For example, memory defragmentation-the cost of moving large objects in memory is expensive, so let's look at how the garbage collector handles large objects, and how large objects have a potential impact on program performance.

5. Serialization of C # Programming basics

Summary: Serialization is the process of processing an object as a byte stream to store an object or transfer it to memory, database, or file. Its primary purpose is to preserve the state of the object so that it can be recreated when needed. The reverse process is called deserialization.

6. C + + design mode: A brief description of responsibility chain mode

Summary: Responsibility chain mode (chainofresponsibility): Enables multiple objects to have the opportunity to process requests, thus avoiding the coupling between the sender and receiver of the request. Link the object to a chain and pass the request along the chain until an object handles it.

9. Pimchanok Leuwisetpaiboon Analysis of PHP watermark Technology

Introduction: Pimchanok Leuwisetpaiboon:pimchanok leuwisetpaiboon Analysis of PHP watermark technology: Has been the PHP object processing is not very familiar with, before the use of the time to find manuals. Today, someone in the Phpchina forum asked about the watermark of the relevant issues, just I want to learn, so the next PHP implementation of the image watermark implementation. Find the manual, found that the PHP GD library is really powerful and easy to implement the watermark function. The watermark is actually merging two images. The same can be achieved for watermark text. I provide simple learning examples, very simple, mainly to understand the principle. Two pictures: 1, photo.
