At the beginning of the use of asana, because of the blind enthusiasm, feel it can completely replace 2 and 3, so a
, XDoclet has developed into a fully functional and Attribute-oriented code generation framework. J2EE code generation is only an application of XDoclet, and the tasks it can accomplish far surpass the generation of J2EE and project documents.
2.2.1 XDoclet taskSo far, we have been discussing how to use XDoclet to generate code. But in fact, we should say that we use a specific task of XDoclet to generate code, such as [Definition: task is a high-level concept for generating applications using c
Parallel programming mode-Master-Worker mode and masterworker Mode
Introduction
The Master-Worker mode is a commonly used parallel design mode. Its core idea is that the system has two process protocols: Master process and Worker process. The Master process is responsible for receiving and allocating tasks, and the Worker process is responsible for processing subtasks. After the Worker processes process the sub-tasks, the results are returned to th

Then, the Task Scheduler (plan) is used to reorganize the subtasks to outline the user's actual operation process.When designing a brand new product, hierarchical task analysis allows you to explore the different ways in which users can accomplish the same tasks. The design needs to be able to meet the behavioral paths of these
these instructions, you can see the fundamental importance of forkjoinpool.

How to understand the efficiency of mobile product interaction?
We can understand the interaction efficiency from the task model. The general mobile end of the use of behavior can be simplified to the following figure: the user through the interactive operation to complete a series of tasks, consumption

fork-join Framework (Java 7)
Java after JDK7 joined the framework of parallel computing fork/join,fork/join is divided, Fork is a large task split into several subtasks, subtasks are calculated separately, and join is to obtain the results of the subtasks, and then merge, this is a recursive process. When subtasks are
Master-worker mode is one of the common parallel patterns, its core idea is that the system has two processes working together: master process, responsible for receiving and assigning tasks, and worker processes, responsible for handling subtasks. When the worker process completes the subtasks, the results are returned to the master process, summed up by the master process, and the final results are obt

Overview
The previous article "JDK": The executor framework refers to the executor framework, while the Fork-join framework also relates to the executor framework for multithreaded parallel operations.
The Fork-join framework has its own scope of application. If an application can be decomposed into multiple subtasks, and the result of combining multiple sub-tasks can get the final answer, then this application is suitable to be solved with fork-join
