Objects
Some Asterisk configuration files also create objects. The syntax for objects is slightly different than for settings. To create an object, you specify the type of object, an arrow formed by the equals sign and a greater-than sign (=>), and the settings for that object.
Tip
Confused by Object Syntax?
In order to make life easier for newcomers to the Asterisk configuration files, the developers have made it so that you can also create objects with an equal sign. Thus, the two lines below are functionally equivalent.
some_object => settings
some_object=settings
It is common to see both versions of the syntax, especially in online Asterisk documentation and examples. This book, however, will denote objects by using the arrow instead of the equals sign.
[section-name]
label1=value1
label2=value2
object1 => name1
label1=value0
label3=value3
object2 => name2
In this example, object1 inherits both label1 and label2. It is important to note that object2 also inherits label2, along with label1 (with the new overridden value value0) and label3.
In short, objects inherit all the settings defined above them in the current section, and later settings override earlier settings.
