structure, the "Hollywood Rule": "Don ' t call Me,i will calls you.", that is, a parent class invokes the operation of a subclass, not the other way around.(3). The type of the template invoke operation has specific operations, specific abstracclass operations, primitive operations, factory methods, hook operations. The primitive operation is less defined.(4). The name of these redefined actions in Android likes to prefix the method with a suffix on.

Disadvantages(1) The execution result of the subclass affects the parent class, which affects the readability of the code.5.

In the template method pattern, you can put the same code in the parent class and put different method implementat

parts can continue to be extended by inheritance.2. Extract the public part code for easy maintenance.3. The behavior is controlled by the parent class, the subclass is implemented, the basic method is implemented by subclasses, so the subclass can increase the corresponding function by extending the method, and conform to the open and closed principle.Template Method Pattern disadvantageThe template method pattern reverses the reading order, and we

The template method mode, I personally think, is still a design model that is more useful, and is also a more studious and understandable. We will continue to understand it by simulating a scenario. Now let's take a look at the tea process. First, we need to boil a pot of water, then put tea in the teapot, add the boiling water, and wait for the tea to soak. After the previous two discussions, you should ha

Template templates Schema Definition:Defines the skeleton of an algorithm in an operation, delaying execution of some steps into its subclasses. With Java's abstract classes, it is often used in template mode, so template mode usage is common. And it's easy to understand and use. Public abstract class benchmark{/** * The following action is what we want to comple

Template Method mode: defines the execution skeleton of an algorithm and delays the implementation of a specific algorithm to the completion of the subclass. The template method mode requires collaboration between designers who develop abstract classes and specific sub-classes. One designer is responsible for providing the outline and skeleton of an algorithm, while other designers are responsible for provi

Template method Mode:Defined:Defines an algorithmic framework in an operation, and delays some steps into subclasses. Enables subclasses to redefine some specific steps of the algorithm without altering the structure of an algorithm.The template method pattern is very simple and only uses the Java inheritance mechanism, but it is a very wide application pattern.In a software development project, if the same

Statement: This series of blog reference "Big Talk design mode", author Geoscience. The template schema prepares an abstract class, implements some of the logic in concrete ways and concrete constructs, and then declares some abstract methods to force subclasses to implement the remaining logic. Different subclasses can implement these abstract methods in different ways, thus having different implemen

indeterminate steps in the template function are replaced by abstract functions; When the client wants to use this template function, it needs to create a subclass and override the abstract function of the abstract class.When to use?When a similar function is used in more than one place, it is common practice to copy the code and change some places slightly. The reuse rate for this practice code is too low
