1. Scenario Mode
When discussing the factory method mode, I mentioned an application framework for exporting data, but I didn't discuss how to implement each method for exporting text. Now let's solve this problem.Assume that the exported file is divided into three parts, the file header, the end of the file, and the file body, regardless of the format.Document Header: Number of the branch or outlet, date of data exportEnd of file: outputFile body: Table NameExport data to text files and XML fil
Builder Mode
The builder model can separate the internal appearance of a product from the product generation process, so that a building process can generate product objects with different internal appearances.
Object Construction
In some cases, an object has some important properties and cannot be used as a complete product until they have no proper values. For example, an email contains the send
Recently learned Angularjs, found using its own $http.post back to PHP to send data, PHP received the problem. Like what:
$http. Post ("php/getroleright.php", {rr: $scope. Currselect}). Success (function (response) {·});PHP usage
$_post[' RR ']Cannot receive the passed-over parameters.
Open Firebug found actually success, tossing the long time only found that it is only the format of transmission and ordinary transmission format such as the $.post

Freely scale your project: Builder mode, extended builder
Because a complex object has many components, such as a car, a wheel, a steering wheel, an engine, and various small parts, how can we assemble these components into a car, this assembly process is long and complex. In this case, in order to hide implementation details from the outside during the construction process, you can use the

Builder mode
Separating the construction of a complex object from its representation allows the same build process to create different representations.
OverviewWhen the system is ready to provide users with an internally complex object, you can use the generator patt
Builder mode Definition: separates the construction of a complex object from its representation so that the same build process can create different representations.The builder pattern is a step-by-step creation of a complex object that allows the user to build them only by specifying the type and content of the complex objects. The user is not aware of the specifics of the build internals. The
Key points of the builder mode:
The builder mode is mainly used"Build a complex object in steps ". In this case, "step-by-step" is a stable multiplication, while all parts of complex objects change frequently.
The builder mode mainly dealsFrequent demand changes for "various parts of complex objects. ItsDisadvantage:It is difficult to cope with changes in the dem

The builder pattern is somewhat similar to the previous abstract factory pattern, but more powerful than the abstract factory pattern, the builder pattern can be seen as two parts, one builder, and the other is that the basic idea of Director,builder is the abstract factory, While the director exists to make the use of
Idea: Since the interstellar picture is made up of several parts: the map (the terrain and the minerals), the building, the troops. Then we think of them as parts, assembled to be the final product (the whole picture).

What is
the created object to be inconsistent in its state. This will appear in multithreaded programs. For example, Cocacola.setsodium (35); Before executing this code, the object CocaCola has already been used by other threads, which results in the use of a CocaCola object that is not in the correct state. simply put, the object is created, and the code that sets the state of the object is not atomized. --------------------------------------------------------------------------------------------------
