WireData class

WireData is the base data-storage class used by many ProcessWire object types and most modules.

WireData is very much like its parent Wire class with the fundamental difference being that it is designed for runtime data storage. It provides this primarily through the built-in get() and set() methods for getting and setting named properties to WireData objects. The most common example of a WireData object is Page, the type used for all pages in ProcessWire.

Properties set to a WireData object can also be set or accessed directly, like $item->property or using array access like $item[$property]. If you foreach() a WireData object, the default behavior is to iterate all of the properties/values present within it.
