Represents an operator that obtains a Map entry, an indexed value, a property value, or an indexed property value of an object. The following are the rules for evaluating this operator:
Evaluating a[b] (assuming a.b == a["b"]) a is null return null b is null return null a is Map !a.containsKey (b) return null a.get(b) == null return null otherwise return a.get(b) a is List or array coerce b to int (using coercion rules) coercion couldn't be performed error a.get(b) or Array.get(a, b) throws ArrayIndexOutOfBoundsException or IndexOutOfBoundsException return null a.get(b) or Array.get(a, b) throws other exception error return a.get(b) or Array.get(a, b) coerce b to String b is a readable property of a getter throws an exception error otherwise return result of getter call otherwise error@author Nathan Abramson - Art Technology Group @author Shawn Bayern @version $Change: 181177 $$DateTime: 2001/06/26 08:45:09 $$Author: luehe $
