Property access

Provides a reference for the syntax used to access properties in OPL.

There are two ways of accessing a property value.

Table 1. Property access syntax
Syntax	Effect
value.name	Returns the value of the `name` property of `value`, or the undefined value if this property is not defined. See Identifiers for the syntax of `name`. Examples: `str.length getCar().name` Because `name` must be a valid identifier, this form cannot be used to access properties which do not have a valid identifier syntax. For example, the numeric properties of an array cannot be accessed this way: myArray.10 // Illegal syntax For these properties, use the second syntax.
value[name]	Same as the previous syntax, except that this time `name` is an evaluated expression which gives the property name. Examples: str["length"] // Same as str.length getCar()[getPropertyName()] myArray[10] myArray[i+1]
