Setting a value into a object using reflection
- by marionmaiden
Hello
I have an object that has a lot of attributes, each one with it's getter and setter. Each attribute has a non primitive type, that I don't know at runtime.
For example, what I have is this:
public class a{
private typeA attr1;
private typeB attr2;
public typeA getAttr1(){ return attr1; }
public typeB getAttr2(){ return attr2; }
public void setAttr1(typeA at){ attr1 = at; }
public void setAttr2(typeB at){ attr2 = at; }
}
public class typeA{
public typeA(){
// doesn't matter
}
}
public class typeB{
public typeB(){
// doesn't matter
}
}
So, using reflection, I obtained the setter method for an attribute. Setting a value in the standard way is something like this:
a test = new a();
a.setAttr1(new typeA());
But how can I do this using reflection? I already got the setAttr1() method using reflection, but I don't know how to create a new typeA object to be inserted in the setter.
