6th Chapter 3 "Monkeyrunner Source Analysis" Monkey principle-Event Source-Event Source Overview-command translation class

Each string command from the network needs to be parsed, but some are executed directly in the parsing process, while others need to create the corresponding event class instance after parsing and add it to the command queue for execution. This part of the job is to command the translation class. So we're going to go down here. What is the Monkeycommand class in the Monkeysourcenetwork category:

Figure 6-3-1 Monkeycommand Genealogy

The Monkeycommand in the middle of the diagram is an interface that defines the Translatecommand method, which is a string command, a list of parameters, and a command queue that all implementation classes must implement to parse the command string:

• If the command string needs to establish a corresponding monkeyevent instance, the command string is translated into the corresponding Monkeyevent instance and added to the incoming command queue
• If the command string does not need to establish the corresponding Monkeyevent instance, then parse the command string directly and then return

command string format	command Translation class	MR support	comments
Touch down X Y	Touchcommand	Is	x Representative x coordinates, y Representative y coordinates
Touch Up X Y	Touchcommand	Is	Ditto
Touch Move x Y	Touchcommand	Is	Ditto
Tap x Y	Tapcommand	Is	Ditto
Press Name	Presscommand	Is	Name represents a key name, such as "Menu", "HOME", "SEARCH" wait
Key down Name	Keycommand	Is	Ditto
Key up Name	Keycommand	Is	Ditto
GetVar Name	Getvarcommand	Is	name represents a property name
Listvar	Listviewscommand	Is
Type line	Typecommand	Is	Line represents the input string
Wake	Wakecommand	Is
ListViews	Listviewscommand	Is
QueryView	Queryviewcommand	Is
Getrootview	Getrootviewcommand	Is
Getviewwithtext	Getviewswithtextcommand	Is
Done	N/A	Is	test Complete, Monkey will stop when the command is received Socket Monitor
Quit	N/A	Is	test request exits, Monkey will not stop when received Socket Monitoring,
Flip Open	Monkeyflipevent	Whether	Monkeyrunner sending these two commands is not supported
Flip Close	Monkeyflipevent	Whether
Trackball DX dy		Whether
Deferredreturn	Deferreturncommand	Whether	This command is more special, and the thing to do is to wait for one command to complete and then execute another command. However , there is no support in the Monkeyrunner framework.

Table 6-3-1 command string and corresponding command translation class reference table

All the classes in Monkeycommand are actually internal classes, such as command translation classes related to network commands, or subclasses of Monkeysourcenetwork, or subclasses of Monkeysourcenetworkvars, Otherwise it is Monkeysourcenetworkviews's subclass:

Figure 6-3-2 Command translation class as the inner class of the event source

Once the event source gets to the string command it is convenient to call the internal command translation class through Command_map to translate the command, so we can also think that the event source relies on the corresponding command translation class to do things:

Figure 6-3-3 Event source Dependent command translation class

In the next section we go through an example to see how the event translation class translates the string commands sent by Monkeyrunner and translates them into event instances.
