Is it possible to dynamically set properties of an `Object` using Apex?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
Background
I would like to be able to dynamically set properties of an Object (not SObject).
Given this class:
public class Invoice {
public String Ref { get; set; }
}
I would like to be able to do this:
Invoice inv = new Invoice();
inv.put('Ref', 'REF123');
But when I do Execute Anonymous Apex with above code, I this error:
ERROR: Compilation failed.
! ERROR: Line: 3, Column: 12
! Method does not exist or incorrect signature: void put(String, String)
! from the type Invoice
ERROR: Execution failed.
Question
- Is it possible to dynamically set properties of an
Object(notSObject) using Apex? - How would I dynamically set a property of an
Objectusing Apex?

For some isolated cases - yours is one of them - there is this (ab)use of the serialize methods:
Invoice inv = (Invoice) JSON.deserialize(JSON.serialize(new Map<<String, Object>{
'Ref' => 'REF123'
})), Invoice.class);
Here, the capability of JSON.deserialize to create an instance of the specified type and set the properties of the instance is being used.
But in general, Apex is missing the map-like behavior for objects or a reflection API.
