## Package com.install4j.api.context Description

This package contains classes that allow you to interact with the installer and its environment.

See the API overview for general remarks on how to use the install4j API.

The `Context` interface contains all methods that are available in both installer and uninstaller. Concrete interfaces are `InstallerContext` and `UninstallerContext`.

Context objects are available as parameters in all script/expression properties in the install4j GUI.

Context objects are passed to the `install` and `uninstall` methods of actions. Screens and form components receive an appropriate context via a setter method after they are constructed.
