I have seen a article on the memory release of memory in Flash, so I did the following experiment.
Var newPerson: Person = New Person ("Nate", 32);
Var Person_1: Person = New Person ("Nate", 32);
Var Person_2: Person = New Person ("Jane", 28);
Trace (Person_1.ShowInfo ());
//out.print: My name is: Nate, my age is: 32 years old
Trace (Person_2.showinfo ());
//out.print: My name is: Jane, my age is: 28 years old
TRACE (NewPerson.ShowInfo ());
//out.print: My name is: Nate, my age is: 32 years old
VAR PRESON_0 = NewPerson;
NewPerson.age = 26;
NewPerson.name = "RERD";
TRACE (NewPerson.ShowInfo ());
//out.print: My name is: RD, my age is: 26 years old
TRACE (Preson_0.showinfo ());
//out.print: My name is: RD, my age is: 26 years old
TRACE (PRESON_0.AGE);
//out.print:26
Trace (PRESON_0.NAME);
//out.print:rerd
// *** You can see a copy of the copy from it, just point the new object to an address of the memory.
//
DELETE NewPerson;
TRACE (NewPerson.ShowInfo ());
//out.print:undefined
TRACE (Preson_0.showinfo ());
//out.print: My name is: RD, my age is: 26 years old
// *** Although the first object is deleted, because there is still an object pointing to the memory address, the memory is still not released.
TRACE (PRESON_0.AGE);
TRACE (PRESON_0.NAME); So delete does not necessarily release memory
