Detailed Description

Common context for GraalVM Languages.

Encloses the following global routines/components:

• Initialization/TearDown of the GraalVM Isolate.
• Registration of global logging callbacks.
• Setup of the global engine.
• Provides access to the garbage collector for event registration.

This class can be specialized to:

• Provide custom callbacks for the global logging functions.
• Create a custom Engine to be used in the contexts created from this class.
• Provide custom configuration for the garbage collector.
