Alternative to simulink transparent subsystem -

-

i need organize set of elements in simulink. first method create subsystem. problem subsystem elements inside no longer visible. alternative method create colorized box , put behind set of elements background. makes lot of troubles during selection of elements.

the ideal method have subsystem transparent can see elements inside it. can make large , see inside without opening it.

what feasible alternative method?

enter image description here

knowing there no support simulink doing this, possibility use mask icon shows content. following rough prototype mask code:

model='s1/subsystem'; loc=fullfile(pwd,[model,'.png']); print(['-s' model], ['-dpng'], '-r300', loc); image(loc); port_label('input',1,'in1'); port_label('output',1,'out1');

enter image description here

obviously prototype has multiple issues must addressed when using code:

  • remove hard-coded directory.
  • set in- , outports automatically.
  • create required folder structure. (folder s1 must created once manually)
  • scale subsystem block make image good
  • work if pwd not directory model stored in

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
