Example:-
// creating a generic object with some properties we need
myObj = {align:"left", color:0xFF0000, name:"arul", gender:"male"};
//creating a textformat object
myTextFormat = new TextFormat();
//method 1
myObj.copyProperties(myTextFormat, "#align#color#")
//myTextFormat now has align and color properties
//method 2
myObj.copyProperties(myTextFormat, "#name#gender#",true)
//myTextFormat now has all the properties copied except name and gender
