CreateObject

Creates a new object representation according to the {@code type} and {@code className} arguments.

Available types are:

  • class/component - Creates a new instance of a BoxLang class (Default if not used)

  • java - Creates a new instance of a Java class

  • {anything} - Passes the request to the {@code BoxEvent.ON_CREATEOBJECT_REQUEST} event for further processing

If the type requested is not supported, then it passes to an interception call to the {@code BoxEvent.ON_CREATEOBJECT_REQUEST} event, so any listeners can contribute to the object creation request (if any). If there are no listeners, an exception is thrown.

You can also target an explicit class from a loaded BoxLang module by using the {@code @moduleName} suffix. Example: {@code createObject( 'class', 'class.name.path@module' )}

The properties is an optional argument that can be used to pass to the object creation process according to the type.

  • class/component - The properties are not used

  • java - The properties can be a single or an array of absolute path(s) to a directory containing Jars/Classes, or absolute path(s) to specific Jars/Classes to classload

  • {anything} - The properties can be any object that the listener can use to create the object

IMPORTANT: This does NOT create an instance of the class, for that you will need to call the {@code init()} method on the returned object.
