Abstract ClassAbstract class is supported in ZNOW. Creating an abstract class is similar to creating a class. The only difference is that there must be some abstract methods in an abstract class. var Person=Class({
init:function(name){
this.$name=name;
},
setJob:function(job, hrs){
if(hrs > 8) return false;
this.$job=job;
return true;
},
work:ABSTRACT(), //declare an abstract method
$job:false,
$name:false
});
Like many other programming languages, instances cannot be created from abstract classes. In ZNOW, it wont throw exceptions but it will log the error and return null; |
