An Engine is a Container that represents the entire Catalina servlet engine. It is useful in the following types of scenarios:
The child containers attached to an Engine are generally implementations of Host (representing a virtual host) or Context (representing individual an individual servlet context), depending upon the Engine implementation.
If used, an Engine is always the top level Container in a Catalina
hierarchy. Therefore, the implementation's setParent()
method
should throw IllegalArgumentException
.
