I wrote a function that makes a deep copy of any type. I started from
franco's function for arrays. posting it in case it helps anyone. and
in case someone sees something wrong with it. it's 5x faster than my
first attempt... haxe.Unserializer.run(haxe.Serializer.run(v)).
/**
deep copy of anything
**/
public static function deepCopy<T>( v:T ) : T
{
if (!Reflect.isObject(v)) // simple type
{
return v;
}
else if( Std.is( v, Array ) ) // array
{
var r = Type.createInstance(Type.getClass(v), []);
untyped
{
for( ii in 0...v.length )
r.push(deepCopy(v[ii]));
}
return r;
}
else if( Type.getClass(v) == null ) // anonymous object
{
var obj : Dynamic = {};
for( ff in Reflect.fields(v) )
Reflect.setField(obj, ff, deepCopy(Reflect.field(v, ff)));
return obj;
}
else // class
{
var obj = Type.createEmptyInstance(Type.getClass(v));
for( ff in Reflect.fields(v) )
Reflect.setField(obj, ff, deepCopy(Reflect.field(v, ff)));
return obj;
}
return null;
}
