Direct Access

The simplest way to make property data available is direct access. That is, the read and write parts of the property declaration specify that assigning or reading the property value goes directly to the internal-storage field without calling an access method. Direct access is useful when you want to make a property available in the Object Inspector but changes to its value trigger no immediate processing.

It is common to have direct access for the read part of a property declaration but use an access method for the write part. This allows the status of the component to be updated when the property value changes.
