Properties are a way to create attributes/fields/data for your object, which can also adhere to inheritance rules. They are almost the same as fields in Java. In CFML, they can also be used to describe further capabilities for RESTFul/SOAP web services and Hibernate ORM. If
accessors are enabled, CFML will track those properties in the
variables scope according to their name and create automatic getter and setter methods for those properties. (https://cfdocs.org/cfproperty)
property name="firstName" default="";property name="lastName" default="";property name="age" type="numeric" default="0";property name="address" type="array";
property construct can also have different name-value pair attributes that can enhance its functionality. You can find all of them here: https://cfdocs.org/cfproperty. Below are the most common ones:
type - A valid CFML type
default - Default value when the object is created, else defaults to
setter - Generate a setter method or not, defaults to true
getter - Generate a getter method or not, defaults to true
Please note that in CFML you can also declare these attributes via annotations in the comments section, weird, I know!
/*** The user age* @type numeric* @default 0*/property name="age"
