What is executor design pattern?
Executor Design pattern can be defined as a particular type of design pattern that serves the purpose of decoupling the execution of a task from the real task taken by the user with the help of executors. It decouples the submission of a command from the execution of that very command.
What is the motivation behind using the Command design pattern?
The main motivation for using the Command pattern is that the executor of the command does not need to know anything at all about what the command is, what context information it needs on or what it does. All of that is encapsulated in the command.
What are the advantages of Executor framework?
ExecutorService abstracts away many of the complexities associated with the lower-level abstractions like raw Thread . It provides mechanisms for safely starting, closing down, submitting, executing, and blocking on the successful or abrupt termination of tasks (expressed as Runnable or Callable ).
How to create an instance of a Command Executor?
In your plugin’s onEnable () method, you need to create an instance of your new command executor class, and then make a call like getCommand (“basic”).setExecutor (myExecutor);, where “basic” is the command we want to handle, and myExecutor is the instance we created. //
How to create a class for a commandexecutor?
If im correct (probably not) you need to make a new class and make a new method with an appropriate name. Put the code from your onEnable that you want in the other class in the method (maybe needs tweaked) and then in your onEnable call upon that method. What do you mean? Click to expand… Click to expand… He wants all that in another class.
Which is a characteristic of a command pattern?
Identification: The Command pattern is recognizable by behavioral methods in an abstract/interface type (sender) which invokes a method in an implementation of a different abstract/interface type (receiver) which has been encapsulated by the command implementation during its creation. Command classes are usually limited to specific actions.
How does the UML class implements the command interface?
The Command1 class implements the Command interface by performing an action on a receiver ( receiver1.action1 () ). The UML sequence diagram shows the run-time interactions: The Invoker object calls execute () on a Command1 object. Command1 calls action1 () on a Receiver1 object, which performs the request.
