What is the best method to deep clone objects in actionscript?
989
A shallow copy of an object references the original. So any changes made to the original object will be reflected in the copy. A deep copy is a copy of all elements of the original object. Changes made to the original object will not be reflected in the copy.
Copy an Object With Object.assign() was the most popular way to deep copy an object. Object. assign() will copy everything into the new object, including any functions. Mutating the copied object also doesn't affect the original object.
Deep Copy: It is a process of creating a new object and then copying the fields of the current object to the newly created object to make a complete copy of the internal reference types. If the specified field is a value type, then a bit-by-bit copy of the field will be performed.
Deep copy is creating a new object and then copying the nonstatic fields of the current object to the new object. If a field is a value type --> a bit-by-bit copy of the field is performed. If a field is a reference type --> a new copy of the referred object is performed.
The best method to do this is by using the ByteArray with the method writeObject. Like this:
function clone(source:Object):* {
var copier:ByteArray = new ByteArray();
copier.writeObject(source);
copier.position = 0;
return(copier.readObject());
}
